Stem-borers of cereals in Sahelian West Africa relative importance and control uri icon

abstract

  • A brief account of the distribution and relative importanceof the major stem-borer species of cereals in the Sahel is given. The level of parasitism is usually low and populations of the major parasites: Apanteles sesamiae, Pedlobius furvus and Terasticus atriclavus increase only towards the end of the growing season. Further investigations on local natural enemies and of exotic species are suggested. Other control measures involving the use of resistant varieties and cultural practices are presented as modalities within the context of a viable integrated pest innagement program
