Abstract

Among six intercrops evaluated, cotton (Gossypium hirsutum L.) intercropped with sunflower and cowpea in paired row system were favourable for the conservation of Chrysoperla carnea (Stephens), Cotton alone was comparatively less favourable to the multiplication of C. carnea, which correspondingly recorded more population of insect pests. The population of C. carnea did not show any influence on the population of Amrasca devastans Ishida.
