Effects of biopesticide practices on entomofauna and tomato (Solanum lycopersicum) production in the ISAE experiment station (Dakar-Senegal)

Abstract

In Senegal, the tomato represents 22.5% of the overall vegetable production estimated at 70,000 tons and is the second most important vegetable crop. However, its production is exposed to many constraints, including the threat of insects. To face the problems posed by these pests, it is necessary to implement effective control methods, capable of reducing the pest population to a tolerable economic threshold. For this reason, this study was conducted in the experimental field of application and incubator of ISAE at UCAD in 2021 in order to test the effectiveness of biological controls on insect pests and tomato yield. A Fisher experimental set-up consisting of three (3) blocks divided into nine (9) plots was installed. The results of this study show that the number of insects is significantly higher (14.7) in untreated plants. On the other hand, the incidence of insects is significantly lower (8.08) with plants treated with Capscicum annum than with plants treated with Azadirachta indica (8.5).
