Abstract
Recent studies on the identification and evaluation of the millet stemborer Coniesta ignefusalis female sex pheromone have shown that pheromone technology is promising as a management component. A review of research shows that an effective pheromone trap has been developed and successfully tested in eight countries in West Africa, through the West and Central African Millet Research Network (WCAMRN/ROCAFREMI). A regional wide-scale stemborer monitoring network has been developed and is being implemented. Studies on mass trapping and mating disruption indicate that the two techniques have much potential in C. ignefusalis management. Prospects for the implementation of pheromone technology to manage C. ignefusalis in the context of an IPM scheme are discussed.
Résumé
Des études récentes sur l’identification et l’évaluation de la phéromone sexuelle de la femelle du foreur de tiges de mil, Coniesta ignefusalis, ont démontré que la technologie de gestion du foreur basée sur les phéromones était prometteuses. Une revue de la recherche dans le domaine indique qu’un piège à phéromone fiable a été mis au point et testé dans huit pays de l’Afrique de l’Ouest, à travers le Réseau Ouest et Centre Africain pour la Recherche sur le Mil (ROCAFREMI). Une surveillance régionale à grande échelle a été entreprise et mise en application. Les résultats des tests sur le piègeage en masse et la confusion sexuelle démontrent que ces deux techniques sont prometteuse dans la lutte contre C. ignefusalis. Les perspectives d’application de la technologie basée sur la phéromone dans la gestion de C. ignefusalis dans un contexte schématique de lutte intégrée ont fait l’objet de discussion.
