Strip intercropping in crops can influence insect population activity, increasing or decreasing the population number of pests and natural enemies. For this purpose, the effect of intercropping in strips in the crops of (Maize with nhemba beans, Holoco beans and Crotalaria Juncea) on the management of the funnel caterpillar (Spodoptera Frungiperda) on the corn crop (Zea mays L.) was evaluated. received no chemical treatment. A field trial was established in four different agro-ecological zones with a randomized complete block design (DBCC), with four replicates, and in each replicate with four treatments for a total of 16 treatments, each plot had intercropped legumes and maize where the maize was in the two central rows and the various legumes served as a barrier, four cuts, one of each repetition being pure maize. After corn emergence, all treatments were monitored weekly, counting the funnel caterpillar population and other pests and natural enemies. However, the natural enemies were found more in the plots with the intercropped crop than in pure corn. Pure corn was the most attacked by the caterpillar in relation to intercropped corn, which had the highest yield. There were no significant differences in yield between pure maize (control) and maize intercropped with cowpea, holoco bean and Crotalaria juncea in the three locations only in Gurué.
