Abstract
The paper reviews the work done on the population patterns of Chilo spp. in relation to the phenological stages of sorghum, maize and millets. The stem borer Chilo partellus entered sorghum and maize crops at 2–3 weeks after emergence and continued till harvest. There were 3–4 peaks of larval population during a cropping season. Such studies not only reveal the relationship between the larval population density and the phenological stage of the plants at infestation time, but are also helpful in scheduling and timing pest management strategies.
Résumé
L’article fait un compte rendu des travaux d’échantillonnage de la population de Chilo spp. en fonction des stads phénologiques du sorgho, du maïs et du millet. Le boreur de tige, Chilo partellus s’installe sur les plantes de sorgho et de maïs 2 à 3 semaines après germination, et jusqu à la moisson. Trois à quatre pics de la population larvaire ont été observés durant la saison. Cette étude, a non seulement revelé le rapport entre la densité de la population larvaire et le stade phénologique de la plante, mais a aussi aidé a programmer les stratègies d’intervention pour la lutte integrée.
