Parasitization Of Selected AFrican StemBorers By Costesia Flavipes Cameron And Cotesia Sesaniae (CAMERON) (HYMENOPTERA:BRACONIDAE) With Emphasis on Host Selection And Host Suitability

ABSTRACT Chilo partellus (Swinhoe) is a major pest of maize and sorghum in East Africa and indigenous natural enemies have been unable to maintain the pest population at a level acceptable to farmers. In Kenya, a classical biological control programme was initiated in an attempt to increase natural suppression of Chilo partellus and other stemborers. To do this, a natural enemy of Chilo parfellus, Cotesia flavipes Cameron (Hymenoptera: Braconidae), has been introduced into Kenya from Pakista...
