Status of pyrethroid resistance in the cotton bollworm, Helicoverpa armigera, in Cameroun

Brévault Thierry, Achaleke Joseph. 2005. Status of pyrethroid resistance in the cotton bollworm, Helicoverpa armigera, in Cameroun. Resistant Pest Management, 15 (1) : 4-7.

Résumé : Over the last two years, from 2002 up to 2004, survey of H. armigera susceptibility to pyrethroid insecticides was carried out in order to diagnose control failure in the cotton growing area, in Nothern Cameroon. Vial tests on field-collected larvae and topical applications on wild strains confirmed the loss of pyrethroid susceptibility in H. armigera, both within and between cotton growing seasons. Most control failures reported by farmers in 2004 could be allotted to pyrethroid resistance.
