Abstract
An inventory of pest insect of tomato (Lycopersicon esculentum) was carried out in 2018 in five localities of Foumbot production area to find out the effects of using synthetic insecticides on the worrying insects. The quantity applied and frequency of application was equally assessed and compared to those prescribed by the producers. Caiman B, Cypercal, Parastar, Cybemex and Plusfort are used. The insects were captured weekly during March and February during fruits formation and when they are getting ripe. The results showed that the doses and the frequencies of applications are different from a producer to the other. A total of 6485 insect pests belonging to the order Diptera, Hemiptera and Lepidoptera were captured. The greatest number of insect pests was captured in the locality of Mangoum 1 (19.75%). Bemisia tabaci (Hemiptera: Aleyrodidae) was the most abundant species (62.94%). The damages bring a setback in quantity and quality of the harvest, fruits are not good any more for consumption. The usage of these pesticides without respecting the norms has not reduced the population of the insect pests of tomato at Foumbot, showing that the insects became resistant. We suggest a strict respect of the doses and frequencies and the use of bio-pesticides and essential oils, respectful of the environment.
