A field experiment was conducted during 2003-04 under rainfed condition in Karnataka, India, to study the mechanism underlying a possible reduction in the spotted stem borer (Chilo partellus) and armyworm (Mythimna separata) incidence and yield increase in sorghum (Sorghum bicolor) intercropping with different pulses. Sorghum hybrid CSH-14 was grown as a monocrop and intercropped with red gram (Cajanus cajan) cv. 'Maruthi', groundnut cv. JL-24, soyabean (Glycine max) cv. 'JS-335', green gram, cowpea cv.'C-152' and coriander (Coriandrum sativum) cv. 'Local'. The results showed significant reduction in number of larvae and percentage dead hearts of stem borer in sorghum+groundnut ecosystem followed by cowpea intercropping. Intercropping of red gram and groundnut with sorghum at 2:4 ratio was beneficial in reducing the armyworm incidence and increasing the income.
