Leafy vegetables to which the black nightshade belongs occupy an important place in the world economy and contribute effectively to food security. But their culture is limited by the aggressiveness of pests and diseases. The study was based on a trial in the field in the experimental plots of IRAD-Ekona. Four density levels (T1, T2, T3 and T4) respectively corresponding to distances: random, 20cm x 20cm, 30cm x 30cm, 40cm x 25cm were tested. The results obtained and presented here show that in general, S. nigrum is strongly attacked by three types of insects: aphids, black ants and whiteflies. The citation order marks the order of importance of the attack. Indeed, when the culture densities are large (20cm x 20cm or random), S. nigrum is subject to many attacks. Culture density positively influences certain growth parameters (p ≤ 5%) and the yield of all varieties studied. The high densities (T1 and T2) are an ideal ecosystem for the attraction and development of insects; major disease vectors. The T3 treatment (30cm x 30cm) could be recommended to farmers to improve cultivation techniques and effectively increase their yield.
