Résumé:
This study made it possible to evaluate "in vivo" the insecticidal activity of Mentha piperita hydroalcoholic extract on two aphid species dependent on pepper, It is Aphis gossypii and Myzus persicae. The hydro-methanoic extraction of the leaves peppermint was carried out by the soxhlet method. The extract was tested using the direct contact method or in situ spraying on greenhouse peppers grown in a greenhouse. The results obtained show that the mortality of the two species (A. gossypii and M. persicae) was most marked in the extract at the 20% dose, unlike the other doses and controls. It was noted during this experiment that the methanoic extract showed an interesting efficiency marked by a high mortality of A. gossypii compared to M. persicae
