Abstract
The present study was carried out to understand the impact of climatic conditions on adult life table parameters of Aedes albopictus (Skuse) (Diptera: Culicidae). Thus, strains of Aedes albopictus were collected from two different ecological regions of Rajasthan, India i.e., Kota (semi-arid) and Barmer (arid), and compared under insectary conditions. The result showed that male life expectancy was greater in the Kota strain (8.19 days) than in the Barmer strain (5.91 days) with significant differences whereas no significant differences were found for female life expectancy (Kota: 13.75 days; Barmer: 12.24 days). Barmer strain showed a higher intrinsic rate of increase (rm) (0.25), finite rate of increase (λ) (1.29), and lower doubling time (DT) (2.66 days) than the Kota strain (rm: 0.22; λ: 1.24; DT: 3.12 days) with significant differences which shows more r-strategic pattern in Barmer strain. However, the slobodkin curve for males and females of both strains showed a type II survivorship curve. No significant differences were found for net reproductive rate (R0), mean generation time (T), oviposition schedule, and fecundity parameters. Conclusively, the present study may help in the better prediction of Ae. albopictus population dynamics prevalent in these geographical areas and for implementing the efficient vector management practices.
