Résumé : The major insect pest of cotton and vegetable in West Africa, the bollworm Helicoverpa armigera (Hübner), recently developed resistance to pyrethroids via the overproduction of oxidases, leadmg to control failures in the field. One way to overcome this problem is restriction in pyrethroid use. Tested for six years in cotton, spinosad (Laser®) proved to be efficient for the control of H. armigera, Furthermore, no cross-resistance has been detected in a selected pyrethroid-resistant strain. Spinosad can be recommended to manage bollworm resistant populations in West Africa.
