Abstract: This study proposes to assess the activity of insecticide plants in the far North region of Cameroon. The leaves or bark of four local plants (Azadirachtaindica, Boswelliadalzeilii, Khayasenegalensis and Ocimumcanum) were harvested, dried and powdered for the formulation of insecticidal chopsticks at different doses. Toxicity tests have been conducted on adult culicidae mosquitoes by fumigation. They reveal low levels of mortality after 15 minutes of exposure to the smoke of the chopsticks. Remanence due to chopsticks smoke leads to high rates of mortality after 6 and 24 hours of exposure. Mortality rates increase with the dose of each vegetable powder. Lethal doses were calculated 6 hours after exposure for each plant powder. Those of the leaves of Azadirachtaindica proved to be the most efficient thus with the lowest LD50 value of 36.14%. These vegetable powders can be used as natural insecticides instead of chemical insecticides.
