The pod borer [Helicoverpa armigera Hubner (Lepidoptera: Noctuidae)] is responsible for causing up to 90% damage in chickpea due to its regular occurrence from the vegetative growth to the pod formation stage. In order to manage this problem, growers are tempted to increase the amounts of pesticides, but indiscriminate or injudicious use of pesticides has resulted in residues in the food chain, pesticide resistance, and pest resurgence, in addition to causing harm to non-targeted beneficial organisms and the environment. Here, we reviewed the sustainable approaches to reduce the incidence of pod borer and achieve sustainability in chickpea production systems through the adoption of an integrated approach involving host plant resistance, good agronomic practices, and judicious use of chemical and biological methods. We found that the following major points have been reported to reduce the survival and damage of pod borer: (1) use of resistant varieties (the cheapest and the best method of pod borer management); (2) implementing a number of good agronomic practices, such as early sowing with optimum planting density and fertilizer levels, including inter/trap crops (coriander, mustard, linseed, sunflower, sorghum, and marigold) and installing animated bird perches and T-perches at 2 m distance of predatory zones; and (3) monitoring pod borer through pheromone traps (which is also necessary to understand the major factors influencing pest population and to make the pest control program more effective). Integrating all of these approaches with biological control has shown some encouraging results for sustainable pod borer management and has resulted in high chickpea yields. This review highlights examples of successful management approaches from past studies that were implemented in experimental and farmers’ fields. These approaches can be explored as reproducible practices for managing the pest in locations with similar H. armigera concerns. We conclude that an integrated approach is most effective for long-term sustainable management programs.

Chickpea (Cicer arietinum L.) is a legume crop of the Fabaceae family, Faboideae subfamily. It is also known as gram or Bengal gram, garbanzo, or garbanzo bean, and is sometimes known as Egyptian pea, or chana. Its seeds are high in protein. There are two different kinds of chickpea, Desi and Kabuli, based on the size, shape, and color of the seeds. Nutritionally, it contains 24% protein, 59.6% carbohydrates, and 3.2% minerals (Bakr et al. 2004). It has the ability to fix atmospheric nitrogen and can also tolerate high temperatures during and after flowering (Cumming and Jenkins 2011). It is one of the earliest cultivated legumes: 7500-year-old remains have been found in the Middle East (Bell 2014).
Eleven different insect-pests have been reported as the main damaging pests of the chickpea crop (Rahman et al. 1982). Among these, the pod borer, Helicoverpa armigera (Hubner), is considered to be the most serious insect-pest (Anwar and Shafique 1993), causing on average 30–40% damage to pods (Luckmann and Metcalf 1975; Saleem and Younis 1982; Rahman 1990; Hashmi 1994), which may increase to 80–90% in conducive environments (Sehgal and Ujagir 1990; Sachan and Katti 1994). The chickpea’s economic threshold is one pod borer larva per meter row length (Sharma 1985; Zahid et al. 2008). The past decade has seen three major pod borer outbreaks, causing 10–80% yield losses due to pod damage (Yelshetty 1999). Monetary losses result from the direct reduction in crop yield and the cost of monitoring and controlling insect-pests, particularly the cost of insecticides. The extent of chickpea losses has been estimated at over US$328 million in the semi-arid tropics (ICRISAT 1992). Worldwide, losses due to Helicoverpa in cotton, legumes, vegetables, cereals, etc., exceed US$2 billion and the cost of insecticides used to control these pests is over US$1 billion annually (Reed and Pawar 1982).
2 Biology of pod borer
The pod borer exhibits a facultative diapause, which allows it to survive adverse weather conditions in both winter and summer seasons (Hackett and Gatehouse 1982; CABI 2007) Crop Protection Compendium, 2007 Edition. © CAB International Publishing, Wallingford. The winter diapause is induced by exposure of the larvae to short photoperiods and low temperatures. In China and India, pod borer populations are composed of tropical, sub-tropical, and temperate ecotypes. In subtropical Australia, the pod borer undergoes diapause during the winter, when temperatures are low. High temperatures can also induce diapause. It enters a true summer diapause when the larvae are exposed to very high temperatures (43 °C for 8 h daily), although the proportion of females entering diapause is nearly half compared with that of males. At these temperatures, non-diapausing males are sterile.
3 Nature of damage
The 1st, 2nd, and 3rd instar larvae initially feed on the foliage (young leaves) of chickpeas and a few other legumes, but mostly on the flowers and flower buds of cotton, pigeon pea, etc. Larvae shift from foliar feeders to developing seeds and fruits as larval instar development progresses (Reed and Pawar 1982). The young chickpea seedlings may be destroyed completely, particularly under tropical climates in southern India. Larger larvae bore into pods/bolls and consume the developing seeds inside the pod. In Australia, where the climate is cooler, the pod borer populations build up in spring, attacking chickpea in late spring before moving on to summer crops growing in the sub-tropical regions.
The most important host crops of H. armigera are tomato, cotton, pigeon pea, chickpea, sorghum, and cowpea. Other hosts include dianthus, pelargonium, chrysanthemum, groundnut, okra, peas, field beans, soybeans, lucerne, Phaseolus spp., other Leguminosae, tobacco, potatoes, maize, flax, a number of fruits (Prunus, Citrus), forest trees, and a range of vegetable and flower crops (Chandra and Rai 1974; Gahukar 2002; Multani and Sohi 2002; Kakimoto et al. 2003; CABI 2006). The pod borer attacks crops from seedling to maturity, damaging all parts of the plant (leaves, flowers, and pods). Initially, the larvae feed on the leaves and tender twigs of the chickpea plant, and later, when the pods are formed, the larvae bore into the pods and feed, resulting in low yield.
The young pod borer larvae (1st, 2nd, and 3rd instar) occasionally enter the pod and feed upon the developing chickpea grains, but more often they feed from outside the pod with only the anterior part of its body in the pod (Saxena 1978; Singh and Singh 1987). A detailed study done by Patel et al. (2010) indicated that pod borer caused maximum entry holes at the basal region of chickpea pods irrespective of the genotypes.
4 Management approaches
Detailed knowledge of the life cycle of an insect-pest, and how it is affected by the environment, provides a scope for adjusting the agronomic practices of a crop so as to lessen the effect of the pest. Farmers mainly rely on insecticides for pod borer management. Insecticides are costly, and their indiscriminate use has induced pesticide resistance and caused environmental pollution (Phokela et al. 1990; Armes et al. 1996; Tabashnik et al. 2009; Cothran et al. 2013; Singh and Mandal 2013). In view of the above, it is necessary to manage the pest in a more ecofriendly manner. Efforts have been made towards exploiting the sustainable pest management options such as varietal resistance, agronomic practices, biological control measures, and integrated approaches.
4.1 Pod characteristics and varietal resistance to H. armigera
Many morphological characteristics which contribute to antixenosis have been used to breed pod borer-resistant varieties. Morphological traits such as pod trichome length and density, pod wall thickness, pod length, breadth and area, and number of pods per plant showed influence on pod borer resistance in chickpea (Ujagir and Khere 1987; Hossain et al. 2008a). Trichomes and trichome exudates on plant surfaces play an important role in the host selection process of insect herbivores. The types of trichomes and their orientation, density, and length have been correlated with reduced insect damage in several crops (Jeffree 1986; David and Easwaramoorthy 1988; Peter et al. 1995). The relationship between pod wall thickness and pod borer damage indicated a negative correlation, which suggested that the chickpea genotypes with a thicker pod wall received less pod borer damage. The pod length, breadth, and area of respective genotypes showed a significant effect on the resistance mechanism against pod borer damage. It showed a negative correlation between the pod length, breadth and area, and pod borer damage. However, a positive correlation was found between pods per plant and pod borer damage.
4.2 Breeding resistant varieties
Developing resistant varieties provides a foundation on which to build an integrated control system against any insect-pest. The reduction in pest number through the use of resistant plants is constant and cumulative and incurs almost no additional cost to the farmers. Therefore, the breeding goal should be to identify, characterize, and utilize a genetic mechanism that confers a durable resistance to pod borer (i.e., multiple factor resistance). Developing improved cultivars with resistance to pod borer is simple if a good source of resistance is available and an efficient and practical screening procedure exists that can provide good selection pressure. Depending on the crop’s reproductive system, standard selection procedures can be adopted. Pedigree, bulk, and mass selection approaches have been successfully employed to develop tolerant or resistant cultivars in chickpea. As many traits of quantitative inheritance are sought after in the breeding process, a recurrent selection scheme is very often recommended due to its potential for breaking up undesirable linkage blocks and for accumulating desirable alleles in a single genotype. Such schemes initially require the buildup of sufficiently large populations from repeated selection and intermating between the selected parents. Mutation breeding may be used to create new variability for the characters showing a positive effect on pod borer resistance. Breeding for resistance to insect-pests results in a net return of $300 per $1 of investment in research (Dua et al. 2005).

Earliness with cold tolerance
Parents ICC 506, ICC 10619, and ICCL 84205 with low borer damage were found to be useful in the breeding programs for pod borer resistance (Singh et al. 1991). Pedigree selection was effective in differentiating low vs. high borer damage. Progenies of plants selected as low borer (15.1%) showed significantly greater tolerance (less susceptible) compared to those selected as high borer (16.1%). Correlation between pod borer damage in F2 and F3 progenies was low, but positive (0.26, p < 0.01) (ICRISAT 1981). Pedigree selection for low borer damage under pesticide-free conditions was found effective in identifying borer-resistant lines. Singh et al. (1997) developed ICCV 7 from a cross between H208 and BEG 482 and registered it as resistant to pod borer. Some of the varieties released, such as Vishal and Vijay, showed higher resistance to pod borer damage (Deshmukh et al. 1996a, 1996b). The screening of wild relatives of C. arietinum showed that the incidence of Helicoverpa larvae on C. echinospermum, C. judaicum, C. pinnatifidum, and C. reticulatum was significantly less than the cultivated species (Kaur et al. 1999).
Considering that the resistance to pod borer is polygenic and the loci may vary in different segments on different resistance sources, efforts were made to pyramid genes from several resistant sources. Eight resistant parents were involved in a multiple cross (four single crosses and two double crosses, leading to one eight-way cross) at ICRISAT. The F2 of the multiple crosses was screened in non-sprayed field conditions to select resistant plants. From these, 300 F3–F5 progenies were evaluated in an unsprayed field in 1994–95, and 42 F5 lines were selected for further evaluation. The best F5 progeny (ICCV 95992) showed less than 1% damage compared to 7% damage in the resistant control ICC 506. In the yield test (under unsprayed and rain-fed conditions), ICCV 95992 suffered 8% damage and produced a seed yield of 0.93 t ha−1. The resistant control (ICC 506) showed 8.5% damage and yielded 0.65 t ha−1 (ICRISAT 1996). Although complete resistance is not available, ICC 506 has shown consistently lower pod damage over the years and improved yields under unsprayed conditions (Gowda et al. 1983). However, most of the pod borer-resistant lines are highly susceptible to wilt caused by Fusarium oxysporum f. sp. ciceri. The problem of the linkage between pod borer resistance and susceptibility to fusarium wilt has been overcome with the identification of the lines ICCL 86102, ICCL 86111, ICPX 730020-1-1-1H, IPC 94-93, IPC 94-94, and IPC 94-102 (Singh et al. 1990; Rheenen and Van Rheenen 1991; Chaturvedi et al. 1998), which combine resistance to both wilt and pod borer.

In India, Rajput et al. (2003) evaluated eight chickpea genotypes against pod borer and observed that its larval population ranged from 1 to 50 larvae per plant, with pod damage from 8 to 90% and grain yield from 23 to 1920 g per plot. The genotype C-727 was found to be relatively resistant against chickpea pod borer among the eight tested genotypes. Shafique et al. (2009) screened 13 advanced lines of kabuli chickpea and reported that pod damage ranged from 13.3 to 22.7% on the most and least susceptible lines, respectively. The kabuli chickpea genotype CH 73/02 was a highly resistant genotype showing the lowest pod damage (8.2%). Genotypes CH 72/02, CH 77/02, and CH 80/02 showed moderate resistance and CH 79/02, B 17/03, CH 65/02, and CH 60/02 showed the least resistance in Faisalabad, Pakistan (Nadeem et al. 2011). In Sudan, genotypes Atmore and Flip03-139c recorded a higher level of resistance against pod borer than the Mattama, Hawata, Selwa, Wad Hamed, Jebel Marra, Flip03-127c, and Flip04-9c genotypes, which showed moderately resistant to pod borer (Mansour and Mohamed 2014).
4.3 Agronomic manipulations (cultural practices)
4.3.1 Sowing time
Sowing chickpea at the optimum time is one of the most important factors affecting crop yield. Weather factors, such as maximum and minimum temperatures, sunshine hours, and wind speed, are important in regulating the pod borer population. It was reported that the pod borer larval population is positively correlated with temperature, whereas relative humidity and rainfall inhibit the larval population (Kumar and Bisht 2013; Shinde et al. 2013). The crop sown later suffered most from the pod borer infestation, as compared with that which was sown earlier. Early sowing of chickpea resulted in low pod borer larval population and pod damage percentage in Pakistani (Akhtar et al. 2014) and Indian conditions (Garg 1990; Choudhary et al. 2015; Parmar et al. 2015). The grain yield was also decreased as sowing was delayed, indicating a direct correlation with pest incidence (Borah 1998; Singh et al. 2002). In general, the pod borer larvae population was less in the crops sown in October in comparison to the crops sown in November under Indian conditions (Anonymous 2013). In northern India, larval peaks of Helicoverpa occur during 10–16 standard weeks and, hence, early sowing or use of short duration chickpea cultivars should permit crop maturity before peak pest load. Late-sown chickpeas can also provide a host for the next generation of Helicoverpa and allow a continuous buildup of resistance (Cumming and Jenkins 2011). In the hilly regions with prolonged crop duration, low infestation of the pest in early-sown crops can be attributed to the fact that the Helicoverpa moths generally emerge from diapausing pupae in late March or early April, when the weather starts warming up. The egg laying and development of early instar larvae take place during the 2nd and 3rd weeks of April. The early instars generally remain confined strictly to leaves, while the later instars, which usually cause substantial damage, emerge towards the 3rd to 4th weeks of April. By that time, the pods on the early-sown crops are almost fully developed and very little damage can be inflicted on them. Thus, the early-sown crops escape the period when the later instar larvae infest the pods, whereas the late-sown crops suffer considerably.
In contrast, in Bangladesh the pod borer population was higher in the early-sown crops (October 15 to November 1) and in those with delayed sowing dates from November 1 to 30, where the pest population decreased and then increased again. It was observed that both the early (October 15 to November 1) and late-sown (December and onward) crops received higher pod borer damage and produced lower yield. However, the mid-sown (November 8 to 30) crops received less pod borer damage and produced higher yield. Hence, to ensure higher yield with less pod borer damage, chickpea should be sown within the range of November 8 to 30, and the best sowing date seems to be November 15 (Hossain et al. 2008b).
4.3.2 Plant density/planting geometry
Plant density also affects the extent of damage caused by pod borer. In general, a denser plant population favors increased pod damage (Reed et al. 1987; Naresh et al. 1989; Qadeer and Singh 1989; Begum et al. 1992). However, higher plant densities may not necessarily result in yield loss due to compensation in the total pod number per unit area (Sithanantham and Reed 1979; Pimbert 1990). In any case, farmers have a limited ability to manipulate plant population due to such factors as unreliable seed viability, seedling diseases, and adverse physical soil conditions at crop establishment. Higher plant density and planting geometry likely favor pest growth by creating a micro-climate conducive to their dark-loving Helicoverpa larvae. Population dynamics of Helicoverpa on chickpea revealed that higher population of larvae and pupae and higher-density crops harbored more population than low-plant density crops (Sithanantham et al. 1981; Kant et al. 2007).
Increasing the seed rate results in closer planting geometry which supports a higher Helicoverpa larval population. Increasing the seed rate from 75 to 100 kg ha−1 greatly increased the percentage of pod damage. Further, increasing the seed rate from 100 to 125 kg ha−1 did not show a significant increase in pod damage. But the increased pod damage in higher seed rate did not affect chickpea grain yield due to the higher plant population per unit area, which compensated for the increased pod damage (Anilkumar et al. 2011).
4.3.3 Nutrient management
Fertilizers are primarily applied to produce high yield of a crop, but their use may have an indirect effect on pest attacks. This effect may be positive or negative (Coaker 1987). The higher level of NPK application results in vigorous plant growth that makes the plants bushy, rendering them more susceptible to pod borer. The bushy nature of the plant provides better shelter to dark-loving pod borer, causing increased pod damage (Hossain et al. 2009). Low to moderate doses of NPK fertilizer led chickpea to have lower pod borer infestation, but higher doses of NPK led to higher pod borer infestation (Hossain et al. 2009). The reason for this is not clear. However, it could be stated that such a reduction in pod borer damage might be due to a complex mechanism occurring in the plant system that builds up anatomical features of pods in such a way that it may develop resistance power against the damaging pod borer activity. Increased phosphorous levels drastically reduced the pod borer incidence and increased the chickpea seed yield (Anilkumar et al. 2011). Coaker (1987) cited that the use of fertilizers can also change the physiology of the plant making it more “active” as a host for an insect-pest. Applying organic manures like farm yard manure, neem cake, and vermicompost resulted in the lowest pest population compared to the application of inorganic fertilizers (Rao 2003; Muddukumar 2007; Singh and Singh 2007). Rhizobium inoculation did not have a significant overall effect, but nitrogen application led to a significant increase in pod borer damage (Ramakrishnan et al. 1983).
4.3.4 Inter/mixed cropping systems
Intercropping in the traditional farming system provides insurance against pest and aberrant weather, in addition to its other advantages over sole cropping. It offers an excellent opportunity for ecological maneuvering of the faunal population by bringing about changes in crop geometry and the cropping system, which may have a relevant economic impact on pest damage.
Intercropping chickpea with certain crops has been shown to reduce damage from pod borer. This may be a result of the companion crop harboring higher numbers of natural enemies or non-preference for egg laying by pod borer in a field containing the intercrop. By concealing a plant among other species, which do not offer the same kind of stimuli, it should be possible to reduce the efficiency of the pest’s host seeking behavior and to interfere with its population development and survival (Pimbert 1990).
Intercropping chickpea with linseed, wheat, and mustard, as well as other non-host crops, has been reported to significantly lower the pod damage compared to chickpea sole crops (Lal et al. 1985b; Yadava 1987; Ahmad 2003). Similarly, pod borer damage was reduced by 38.3% in chickpea + wheat mixed cropping as compared to chickpea sole cropping (Ali et al. 1998). Intercropping generally delayed the appearance of major chickpea pests and reduced their incidence, particularly the linseed intercrop (Mehto et al. 1988; Mehta et al. 1989; Prasad and Kumar 2002; Lal et al. 2002; Borah et al. 2010). According to Tripathi et al. (2008), the minimum larval population and the highest chickpea grain yield were found in chickpea + mustard, followed by chickpea + barley and chickpea + wheat. Similar results have also been supported by Prasad and Chand (1989), Hossain (2003), and Reena et al. (2009).
Coriander and other nectar-rich plants encourage parasitoid activity. Chickpea intercropped with coriander harbored the minimum Helicoverpa population and reduced the incidence of pod borer (Sekar et al. 1996; Nath and Chakravorty 2005; Pandey and Ujagir 2008; Singh and Pandey 2014; Chandra et al. 2014). It has been observed that the older larvae were preferred by Campoletis illota and the younger ones were attacked more by C. chloridae. The parasitization of the older larvae by C. illota ranged from 7.0 to 12.5% (Nath and Rai 1999). Safflower and sunflower intercropped with chickpea reduced pod damage due to the distribution of larvae among chickpea and intercrop during chickpea pod development stages and also due to the conservation and enhancement of natural enemies in intercropping (Sidde Gowda et al. 2004; Pattar et al. 2012).
4.3.5 Trap crops
Trap crops are grown as a control measure to lure pests away from the cash crop to protect it from attacks. Pests are either prevented from reaching the crop or concentrated in certain parts of the field away from the main crop. The principle of trap cropping relies on pest preference for certain plant species, cultivars, or a certain stage of crop development. Plants produce chemicals, or volatiles, that attract insects for pollination and repel insect-pests. Different species and cultivars produce varying degrees of unique volatiles, allowing certain species or varieties to repel insect-pests more strongly than others, making them suitable as a trap crop. The two primary techniques utilized in trap cropping are (1) selection of a more preferred plant species or cultivar grown at the same time as the main crop and (2) planting the same species and cultivar as the main crop, timed to be at the most preferred stage of development before the main crop. Whether using the same or a different species, it is essential that the trap crop be more attractive than the main crop.
Trap cropping offers several benefits in a pest management system. When trap crops successfully attract pest populations, damage to the main crops is limited; therefore, main crops seldom require treatment with insecticides. When insect-pests are highly concentrated in trap crops, they can be treated in a localized area instead of treating the entire field. Savings resulting from reduced pest attack and insecticide use may substantially outweigh the cost of maintaining crops that do not provide economic income. Reduced damage to main crops also increases their expected marketable yield. Further, a variety of plantings and increased concentration of insect-pests may attract natural enemies, enhancing naturally occurring biocontrol.
The trap crop is planted to attract pod borer emerging from diapause. The trap crops are destroyed before larvae commence pupation. As a result, the overall pod borer pressure on crops is reduced, resulting in greater opportunity for adopting soft control options, reduced insecticide use, and greater activity of the natural enemies. The trap crops used either marigold or sunflower and were raised in different ratios and border rows. The pod damage percentage was low when the trap crops were grown in a ratio of 5:1 to 7:1. Trap crops along border rows, alone, recorded 11.24 and 34.05% pod damage in marigold and sunflower trap crops, respectively (Anonymous 2009).
4.3.6 Bird perches
Several species of insectivorous birds have been found to feed on crop insect-pests, including pod borer (Chakravarthy 1988), which have been known to reduce the larval population to the extent of 84% in Punjab, India. Among the predatory birds, black drongo, house sparrows, blue jays, cattle egret, rosy pastor, and mynah are common predators on a large number of H. armigera and lepidopteran insects of chickpea, pigeon pea, and groundnut crops (Gokhale and Ameta 1991). Though the world is bestowed with a rich heritage of avian diversity (Ali and Dillon 1983), the beneficial role of insectivorous birds in insect-pest management has not received much recognition beyond faunistic documentation. This is mainly due to the over-dominance of broad-spectrum insecticides in the plant protection scenario (Gopali 1998; Gopali et al. 2007, 2008). Therefore, the development and implementation of eco-friendly management of the chickpea pod borer is of paramount importance in achieving sustainable production.
The sunflower acted as the most suitable live bird perch in the chickpea ecosystem, as it is a very fast-growing plant and provided rigid support for alighting insectivorous birds right from the vegetative stage until crop maturity. Major predatory birds alighted on the sunflower perch, reducing the larval number within the shortest time. Predatory wasps carrying a large number of larvae were recorded on sunflower plants. The results of a field study revealed that sowing sunflower (50 g seeds ha−1) and sorghum (50 g seeds ha−1) along with chickpea seeds recorded lower larval numbers over the absence of live bird perches (Gopali et al. 2009). The number of coccinellids was higher on sunflower plants. Similarly, the tachinid fly population was the highest, accounting for 75 to 90% of the parasitization of late instar larvae. The study concluded that sowing sunflower (50 g ha−1) and sorghum (50 g ha−1) along with chickpea seeds recorded higher chickpea grain yield with the highest net returns over Profenophos 50 EC at 3.0 ml l−1 (1:5.12) as a standard check. The importance of intercropping sunflower with chickpea in reducing the incidence of pod borer damage was also confirmed by Pattar et al. (2012).
4.4 Monitoring Helicoverpa through pheromone traps
Regularly monitoring the key pest is a vital component of any Integrated Pest Management (IPM) program that helps to take control measures. An effective control strategy always depends on accurate monitoring of damaging stages of the insect. Monitoring or recording is also necessary to understand the major factors influencing pest population to forecast its incidence. Pheromone traps can be incorporated to develop predictive models designed to provide information on probable oviposition patterns, and population abundance of pod borer moth catch is positively correlated with the larval count (Prabhakar et al. 1998). Hossain (2008) reported results on the emergence, promptness, and seasonal fluctuation of pod borer moths for adopting effective pest management technology at Pulses Research Center in Ishurdi, Bangladesh. The results inferred that moth catching was increased gradually and reached its peak in the month of April, then gradually decreased and diminished to zero in the last week of July, and ultimately remained at zero until December. IPM against chickpea pod borer should be initiated from mid-January to manage its population effectively. In Nepal, Prasad and Newpane (1992) reported the maximum amount of moth trapping during the last week of February and the first week of April. The pheromone trap catches were negligible from the 45th to 50th weeks, and again from the 1st to 10th standard weeks in March, trap catches were nil, though the larval population was noticed during pre-winter months. From the 11th standard week, moth catches/traps started increasing and it reached its peak during the 15th to 16th standard week in April. It further decreased until the 19th to 20th standard weeks in May, when the crop was harvested. An increase in pest population during the post-winter months between the 9th and 15th standard weeks has been reported to be a regular trend in northern India (Ahmad 2003). Higher moth catches as well as increased larval population in fields have been observed during April to May (Reena et al. 2009). Yadava et al. (1991) observed pod borer larvae, occurring at all growth stages of the crop, as being less than 0.81 larvae per square meter at the foliage stage and more than 19.02 larvae per square meter at the podding stage.
4.5 Biological control
Biological agents offer an alternative to chemicals for economically viable and ecologically sustainable management of chickpea pod borer. Biological control is a bioeffector method of controlling pests using other living organisms such as plants, animals, bacteria, and virus-based products. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role.
4.5.1 Plant and animal-based extracts
Plant materials are known by farmers to be environmentally benign, safer, and more cost-effective compared to synthetic pesticides (Kamanula et al. 2011), as well as difficult to adulterate when produced or harvested by farmers themselves. The most well-known and commonly used plant extract is azadirachtin, isolated from the seed, wood, bark, leaves, and fruits of the neem tree (Azadirachta indica). Azadirachtin has both antifeedent and growth-retarding properties and can lead to death at any stage in the life cycle, probably by interfering with the neuroendocrine control of metamorphosis in insects (Roy and Dureja 1998). Neem and garlic extract have larvicidal, toxic, repellent, ovicidal, antifeedent and antioviposition effects on insect-pests (Cavallito and Balley 1944; Amonkar and Banerji 1971; Zhu et al. 2001). Applying Neem Seed Kernel Extract (NSKE 5%) treatment reduced the pod borer population in chickpea (Gupta 2007; Pachundkar et al. 2013; Hussain et al. 2016). Leaf, bark, and seed extract from Annona squamosa have pesticidal and insect antifeedent properties (McLaughlin et al. 1997; Alali et al. 1999; Bisen and Bansal 2014). Applying a potent plant pesticide with vermiwash is the best alternative to chemical fertilizer and pesticides (Ma et al. 2000). In India, Mishra et al. (2013) reported a significant decrease in the percentage of pod damage after spraying vermiwash with neem oil and custard apple leaf extract. The vermiwash, combining animal dung and municipal solid wastes with aqueous garlic extract, caused the maximum percentage of reduction in the pod borer infestation rate. The vermiwash obtained from buffalo dung and municipal solid wastes with neem oil and garlic extract were more effective for better plant growth, productivity, and management of the pod borer infestation rate. Integrated application of plant- and animal-based products like pongamia leaf extract (10%) + NSKE (10%) + aloe (0.5%) + cow urine (30%), GCA (2%) + GCK (0.5%), and vitex leaf extract (20%) + clerodendron extract (4%) + cow urine (17%) reduced the maximum larval population with a higher chickpea pod yield (Ladji et al. 2011; Mallapur and Ladji 2010).
4.5.2 Bacteria-based insecticides
Microbial insecticides can be used for managing pod borer populations, and their use would reduce reliance on toxic chemicals released into the agro-ecosystem, e.g., soil toxicity, phytotoxicity, air pollution, and toxicity to mammals and birds. In the developed world, use of Bacillus thuringiensis (Bt)-based microbial insecticide preparations provides an eco-friendly alternative to the generally hazardous broad-spectrum chemical insecticides (Ahmed et al. 2012). The efficacy of Bt can be enhanced by incorporating suitable quantities of acids, salts, oils, adjuvants, thuringiensin (exotoxin of Bt), and chemical insecticides (Salama 1984; Salama et al. 1986; Karel and Schoonhoven 1986; Morris 1988; Ahmed et al. 1989; Ahmed et al. 1990; Khalique and Ahmed 2001, 2003). Applying DiPel 2X and DiPel ES at 1.6 and 1.5 l ha−1, respectively, at early stages of crop infestation (1st, 2nd, and 3rd instar larval infestation) with at least two applications at 7-day intervals resulted in increased chickpea yield (Ahmed et al. 1994; Ahmed 1999; Ahmed and Khalique 2012). Preparations of Bt-based insecticides, with BioBit, Delfin, and DiPel together with NPV showed minimum pod damage (Anonymous 1997). It appears that Bt-based insecticides can act as effective IPM tools if an awareness is developed among farmers about the critical time and method for their safe application.
4.5.3 Virus-based insecticides
Most natural pod borer populations have at least some degree of infection by species-specific nuclear polyhedrosis viruses (NPVs). If the degree of NPV infection can be enhanced, the larval population can be decimated without deleterious effects on any other organisms. In India, extensive studies evaluating NPVs have resulted in the development of technologies for successful application of indigenous NPV preparations to combat pod borer in chickpea. Thakur (1998) applied an NPV preparation at 1.5 ml l−1 and obtained higher grain yield, not significantly different from that with a chemical insecticide (Deltamethrin 2.8 EC applied at 1.0 ml l−1), but significantly more than an unsprayed control. Sharma et al. (1997) reported high pod borer larval mortality in bioagent and chemical insecticide treatments. NPV at 300 LE ha−1 caused a 78.7% reduction in larval population, resulting in 10% pod damage and high grain yield (1.86 t ha−1), whereas the chemical insecticide Endosulfan 35 EC at 1200 ml ha−1 caused a 70.9% reduction in larval population, resulting in 11.2% pod damage and 1.86 t ha−1 grain yield. Many other workers have reported significant reductions in pod borer larval population and, accordingly, less pod damage in chickpea from NPV application, as compared to chemical insecticides and control measures (Narayana 1980; Anonymous 1982, 1983; Chandra 1987; Jayaraj et al. 1987; Pawar et al. 1987; Rabindra and Jayaraj 1988; Balasubramaniam et al. 1989; Vyas and Lakhohaura 1996; Satish et al. 1998; Pokharkar et al. 1999; Hossain et al. 2001; Hossain 2007). An integrated application of NSKE + HaNPV + Panchagavya has resulted in lower pod damage and produced higher chickpea yield (Muddukumar 2007). This might be due to the ovicidal action of NSKE concentration of azadirachtin content leading to egg mortality.
4.6 Integrated management practices
Current sensitivities regarding environmental pollution, human health, and pest resurgence are a consequence of the improper use of synthetic pesticides. Host-plant resistance, natural plant products, bio-pesticides, natural enemies, and agronomic practices offer a potentially viable option for integrated pest management (IPM). They are relatively safe for non-target organisms and human beings. The IPM module comprised resistant varieties, good agronomic practices, pheromone traps, NSKE, HaNPV, etc., and offers an environmentally friendly alternative for effective management of pod borer in chickpea. The most effective IPM module composed of pheromone trapping + sequential release of the bio-control agent (Trichogramma chilonis + Bracon hebetor) + spraying neem seed kernel extract resulted in the best performance for controlling pod borer, followed by pheromone trapping + sequential release of the bio-control agent (T. chilonis + B. hebetor) (Anonymous 2008). The IPM module consisting of sowing chickpea on November 15 and first spraying with HaNPV at 500 LE ha−1 at the 100% plant pod formation stage and second spraying after 7 days with cermethrin at 1 ml l−1 ensures higher yield and return (Hossain et al. 2010). These results are in line with the findings of Suganthy and Kumar (2000) and Vikram et al. (2000), who evaluated different IPM modules composed of insecticides and bio-pesticides. Similarly, Mahmudunnabi et al. (2014) and Anil Kumar et al. (2015) indicated that the IPM package consisting of pheromone traps in addition to the sequential release of bio-control agents and spraying HaNPV revealed the best performance for reducing pod damage and provided the highest yield, by a significant amount. Integrating weeding, hand-picking, and indoxacarb proved to be the most effective in reducing the larval population and pod infestation, and resulted in the maximum grain yield. The larval population of the combined effect of these practices was not significantly different from hand-picking + indoxacarb, weeding + indoxacarb and indoxacarb alone. Hand-picking, in combination with Bt and weeding, also controlled the larval population significantly, but was inferior to the above treatments. The release of T. chilonis Ishii (Hymenoptera: Trichogrammatidae) did not control pod borer. Based on the cost-benefit ratio, hand-picking is the most cost-effective method for controlling pod borer (Wakil et al. 2009).
Chickpea sustainability can be achieved by integrated management of pod borer that comprises a proper integration of measures or practices such as breeding resistant cultivars, adopting good agronomic practices, habitat management, and biological control. Some cultural practices such as early sowing of a resistant/tolerant variety with optimum planting density and fertilizer levels and inter/trap crops (viz., coriander, mustard, linseed, sunflower, sorghum, and marigold) and installing animated bird perches (i.e., sunflower and sorghum), along with chickpea seeds with T-perches at 2-m predatory zones, are optimum for high chickpea yields with sustainable pod borer management. Any single method of approach to pest control may not be feasible; hence, the best alternative is the IPM approach, which is based on the principles of managing the pest rather than aiming at its complete eradication. In view of this, the present review concluded that the use of IPM options, along with growing resistant varieties, good agronomic practices, biological control, chemical control (if necessary), behavioral approaches, etc., reduce the negative impact of insecticides on the natural enemies that are present in the suitable ecological niche and will protect the ecosystem and the environment from toxicological hazards.
