Abstract

99 words

Stemborers cause 50% yield losses in cereal crops. In Kenya Cotesia sesamiae is one of the parasitoids that has been studied in regard to the control of stemborer pests. In this study the reproductive compatibility of three populations of C. sesamiae was investigated using the noctuid S. calamistis and Busseola fusca as hosts. The output of this work has helped to determine the effect of cross mating and oviposition behaviour of C. sesamia strains and has helped to understand the possible consequences of the introduction and redistribution of C. sesamiae for the sustainable control of stem borers in Africa.
