Abstract

In many parts of Africa, field sorghum is attacked by a number of insect pests, notable among them being the sorghum shootfly, a range of lepidopterous stem borers, midge and a complex of head bugs. Studies on yield losses caused by these insects are scanty, yet such information is essential in formulating an IPM strategy for the crop. This study, therefore, describes the various methods of assessing and quantifying the on-farm (pre-harvest) yield losses caused by the above insect pests.

Résumé

Dans plusieurs regions d'Afrique, sorghum de champ est attaqué par plusieur d'insectes, en particulier Atherigona saccata, beaucoup de larve lepidoptères, Contarinia sorghicola, et un complexe de pis de tête. Il n'y a pas beaucoup d'information des pertes à cause cette d'insectes, mais cette l'information est essential pour formulé une stratégie integré pour le plantation. Cette étude décrie les méthodes divers pour assesse et quantifier les pertes avant la moisson à cause les bebettes mentionées.
