IITA IPM project 01: Implementing pheromone traps and other new technologies for control of cowpea insect pests in West Africa through farmer field schools.

Duration: 3 years (2003 to 2005)

Purpose: To evaluate and develop recommendations for the use of botanical insecticides against M. vitrata (in conjunction with pheromone traps) and early season pests such as aphids and thrips; extend the uptake of the pheromone traps and botanical insecticides; improve farmers’ access to pheromone lures and traps, and to botanical insecticides.

Background/description: Previously, R7441 developed pheromone traps to predict infestations of the legume podborer, Maruca vitrata in cowpea in West Africa.  These enable timing of control measures to be optimised. The proposed project will increase food security and economic returns to cowpea farmers by developing a package combining pheromone traps and botanical pesticides for control of M. vitrata, aphids (Aphis craccivora) and thrips, (Megalurothrips sjostedti).  Uptake among poor small-scale farmers in Benin and Ghana will be promoted through farmer field schools facilitated by national agricultural research and extension services, as well as NGOs, operating under the umbrella of the regional, IFAD-funded “Projet de Niébé pour l’Afrique” (PRONAF) project.  Commercial availability of the novel technologies to farmers will be developed in partnership with selected farmers’ organisations trained by NGOs and the local private sector.

Agroecozone(s) and location(s): The savannas in Benin and Ghana

Expected outputs: a) Recommendations developed for the combined use of botanical or conventional insecticides, and pheromone traps, to control M. vitrata and early season pests; b) Uptake increased for pheromone traps and best package of botanical/conventional insecticides for controlling the pest complex; c) Local/regional systems of manufacture and distribution of pheromone traps and lures, and of botanical insecticides developed on a pilot-scale.

Potential impact and beneficiaries: Assuming realisation of the Outputs, the project would improve food security and reduce poverty among small-scale rural farmers in Benin and Ghana by enabling the reduction of costs of pest control in cowpea. This would be brought about by completing development of a pest control package combining pheromone traps for M. vitrata and (ideally) botanical pesticides for control of this pest and two others, aphids (Aphis craccivora) and thrips, (Megalurothrips sjostedti). The project would underpin this by developing the commercial availability of the novel technologies to farmers.
