This study on the effect of insect pests on rice production was conducted in the Far North of Cameroon in the Maga irrigated rice ecosystem. The aim was to determine the biological diversity of insect pests of rice in the Maga rice ecosystem, to assess the damage and dynamics of insect pests on the phenological stages of rice, and to evaluate the effect of the insecticide lynx on insect pests and rice production. The results obtained on biological diversity showed that 2,465 insect pests of rice were collected on the variety IR 46 and 3,264 on the variety NERICA 3. In terms of insect pest damage, the total insect pest loss was estimated at 49.98%, with 26.30% loss at tillering and 23.68% at harvest on both varieties. The chemical insecticide lynx reduced pests at a rate of 12.585% at nursery, 20.4725% at tillering, 9.305% at heading and 8.7325% at maturity. Yields were obtained at 2.13 t/ha for the variety IR 46 and 1.91 t/ha for the variety NERICA 3.
