The coffee berry borer Hypothenemus hampei is the main pest affecting coffee crops worldwide level. This beetle infects 12 commercial species belonging to the genus Coffea. Currently, the insecticides mainly used for the control of this pest are highly toxic to human health and the environment due to their slow degradation in soil. Our main objective in this project is to develop safer strategies (natural insecticides, deterrents, and attractants) to combat this pest. Previous research has shown the insecticidal activity of essential oil extracted from Ylang-ylang leaves (Cananga odorata) against the maize weevil Sitophilus zeamais. Since S. zeamais and H. hampei belong to the family Curculionidae, we tested the potential insecticide activity of C. Ododata. We also tested the insecticide activity of Syzygium aromaticum, Cinnamomun zeylanicum, Callistemon citrinus, and Illisium verum components against the coffee berry borer. In order to perform this task, we obtained the essential oils from flowers, seeds, or leaves of the plants mentioned above by hydrodistillation. To this point, the research suggests that the essential oil of C. odorata could become a prospective organic insecticide against H. hampei.
