ABSTRACT: Bactrocera dorsalis is one of the major constraints on the mango industry in Burkina Faso. To control these insect pests, a number of control methods have been used, including synthetic insecticides that are costly for producers. Overuse of these insecticides often leads to environmental pollution, food poisoning and resistance among the insects. A study of the biological efficacy of organic extracts from eight plant materials (Capsicum annum, Cleome viscosa, Mytragina inermis, Strophantus hispidus, Ocimum basilicum, Cassia nigricans, Cassia occidentalis) on Bactrocera dorsalis was carried out under laboratory conditions. In the laboratory, these plants were extracted using solvents of increasing polarity (n-hexane, ethyl acetate and methanol) according to the Nair method (Kambou et al., 2008). The biological activity test on the development of B. dorsalis was carried out in a randomized Fisher block design with 25 treatments in 10 replicates. Hexane extracts of C. annuum and S. hispidus resulted in 100% inhibition of B. dorsalis development.
