Abstract
In studies on the distribution, importance, natural enemies and control (by plant resistance) of the stem-borers Chilo partellus (Swinh.), C. orichalcociliellus (Strand), Busseola fusca (Fuller), Eldana saccharina Wlk. and Sesamia calamistis Hmps. on sorghum in Kenya in 1981-1982, C. partellus, which was a major pest, infested the crop early, while E. saccharina and S. calamistis infested late and persisted in the crop until it was harvested. Larvae of C. partellus and S. calamistis were able to enter diapause in dry sorghum stalks for several months at the end of the long and short rainy seasons. Sixteen food-plants for the complex of stem-borers are listed, and notes are provided on some natural enemies. Apanteles sesamiae Cam. parasitised 4 species, Dentichasmias busseolae Heinr. parasitised C. partellus, and predators (on one or more species) were the earwig Diaperasticus erythrocephalus (Ol.), the ant Camponotus rufoglaucus (Jerd.) and the coccinellids Cheilomenes spp. Some sources of plant resistance to Chilo partellus and B. fusca were identified
