INSECTICIDAL ACTIVITY OF THREE AROMATIC AND MEDICINAL PLANTS AGAINST Callosobruchus maculatus (FAB..

The toxicity of plant powders from noble laurel (Laurus nobilis) leaves, hot pepper (Capsicum frutescens) fruits, and clove (Syzygium aromaticum) fruits was tested on healthy cowpea seeds against the bruche Callosobruchus maculatus. The contact tests of the three vegetable powders were conducted under laboratory conditions (27°C, 70% RH, and a photoperiod of 14h (light) / 10h (dark) (dark). The findings show that Capsicum frutescense powder has a very powerful effect on the fecundity of C. maculatus females at a dosage of 0.1g, but has a very small effect on the mortality of adults C. maculatus.The powder of Syzygium aromaticum prevents the laying of eggs in C. maculatus females from a dose of 0.5 g and induces complete mortality in all three doses used after 5 days of exposure, while the powder of Laurus nobilis has no effect on the fecundity of C. maculatus females from a dose of 0.5 g. However, for doses greater than or equal to 1g, a slight decrease is observed, resulting in a small lethal effect on adult C. maculatus.
