Abstract

Pearl millet, Pennisetum americanum L. occupies a large proportion of the area growing millets in Africa. Consequently the insect pests that attack this species have received attention over other millets. A list of the major species is presented. Actual data on losses due to insect pests on pearl millet are not readily available. Crop loss assessment methods using incidence and damage ratios are discussed. Quantitative losses determined from insecticide trials at research station are also presented.

Résumé

Le petit mil, Pennisetum americanum L. occupe une grande partie de la région emblavée en mils en Afrique. Les insectes nuisibles qui s’attaquent à cette culture ont retenu plus d’attention, de ce fait, que ceux d’autres mils. Une liste des importantes espèces est présentée dans l’article. Les données réelles sur les pertes provoquées par les insectes nuisibles sur le petit mil ne sont pas facilement disponibles. Les méthodes d’évaluation des pertes de rendement à l’aide des rapports d’incidences et ceux de dégâts sont discutées. Les pertes quantitative déterminées à partir des essais insecticides en ferme expérimentale sont également présentées.
