Abstract

The paper stresses the fact that an integrated pest management system is not a new concept leading to a more stable agroecosystem, but was practiced by the farmers for centuries; host-plant resistance is one of its major components. The system was destabilized by the introduction of new sorghum varieties and hybrids not resistant against the major sorghum insect pests like shootfly Atherigona soccata (Rondani); stem borer, Chilo partellus (Swinhoe); midge, Contarinia sorghicola (Coquillet); and headbugs, Calocoris angustatus (Lethiery). In order to balance the agroecosystem again, an integrated insect pest management system for sorghum has to be developed based on traditional pest management practices. These are host-plant resistance, cultural control and biological control. Insecticides should be used only if absolutely necessary. For a better understanding of such a control approach, a summary of the biology and population dynamics of the major insects is given, together with a brief account on the levels and mechanisms of host-plant resistance so far known. Based on this information, the rainfall pattern, plant duration to maturity, time of planting, natural enemies and insecticides, a sorghum based integrated pest management system is proposed for the monsoon and post-monsoon season in which host-plant resistance alone or in combination with the above mentioned control methods could be used.

Résumé

L'article souligne qu'un système intégré de contrôle des insectes n'est pas un nouveau concept conduisant à un agroécosystème plus stable, mais qu'il a été pratiqué pendant des siècles, par des agriculteurs, la résistance de la plante hôte est un de ses composés majeurs. Le système a été déstabilisé par l'introduction de nouvelles variétés de sorgho et des hybrides non résistant aux insectes majeurs nuisibles au sorgho tels que Atherigona soccata (Rondani), le Chilo partellus (Swinhoe), le Contarinia sorghicola (coquillet) et les Calocoris angustatus (Lethiery). Pour réequilibrer l'agroécosystème, un système intégré de contrôle des insectus nuisibles au sorgho doit être développé, basé sur les pratiques traditionelles de contrôle des insectus suivantes; résistance de la plante hôte, contrôle cultural, contrôle biologique. Les insecticides ne doivent être utilisés que quand c'est absolument nécessaire. Pour une meilleure compréhension d'une telle approche, un résumé des dynamiques de la biologie et de la population des insectes importants est donné avec un text bref expliquant les niveaux et mecanismes connus de la résistance de la plante hôte. Sur la base de ces informations, les types de précipitations, la période avant maturité, moment de la plantation, les ennemis naturels et les insecticides, un système intégré de contrôle des insectes nuisibles au sorgho est proposé pour la mousson et la saison suivant la mousson dans lequel la résistance de la plante hôte seule ou en combinaison avec les méthodes de contrôle citées plus haut pourrait être utilisé.
