Abstract

Management programmes for the use of action thresholds to initiate insecticide treatments for controlling pod-borer, Adisura atkinsoni on field bean were evaluated in comparison with standard sprays on calendar basis. Results of three field experiments revealed that management based on initial spray at peak egg laying on tender pods, followed by sprays to maintain 1.5 flat pod damage/inflorescence realised maximum benefit: cost ratio. This management also resulted in reduced insecticide usage.

Nous avons comparé des programmes d'emploi des insecticides pour limiter l'insecte perceur, Adisura atkinsoni, sur les haricots de champs, Lablab purpureus, basés sur la notion de seuils d'action avec des programmes classiques de pulvérisations d'insecticides periodiques. Les résultats obtenus de trois essais aux champs ont montré que le programme comprenant une pulvérisation initiale d'insecticide à l'époque de ponte maximale d'oeux sur les cosses tendres suivie de pulvérisations pour maintenir les dégâts à un taux de 1.5 cosses plates percées par inflorescence donnait le rapport maximal de bénefices aux coûts. Ce programme conduisait également à une reduction de la consommation d'insecticide.
