In Niger, moringa leaf production keeps market gardeners busy in most urban and peri-urban areas. The economic importance of moringa is well established, given the area planted, its virtues and its contribution to nutritional security and poverty reduction. However, in recent years, moringa productivity has fallen considerably due to the almost constant pressure of defoliating insects. Faced with this situation, growers are using unregistered chemicals of dubious origin, often hazardous to human health and the environment. This study aims to find alternative methods to chemical control, in particular by promoting agroecological management. The study was conducted in a Fisher block design with four (4) replications and four (4) treatments, where the potential of basil, sorghum and maize in the management of moringa defoliating insects was tested. Insect abundances and diversity indices were calculated and compared between treatments. Defoliation levels were determined by treatment. Analysis of the results showed that basil and sorghum reduced insect abundance by 7% and 5% respectively, and increased insect diversity by 8% and 13% respectively with the presence of natural enemies in the plots. Similarly, the results revealed the potential of basil and sorghum to very significantly (Pr = 0.0015) reduce defoliation by 36% and 34% respectively in moringa plots. Sorghum and basil may be better candidates for inclusion in the agroecological management of moringa defoliating insects.
