  • Biological control of millet head miner using Trichogrammatoidea armigera

    —

    by

    This document presents a biological control method against the millet head miner (Heliocheilus albipunctella) in the Sahel using the egg parasitoid Trichogrammatoidea armigera. It details a low-cost mass-rearing technique based on sterilized eggs of Corcyra cephalonica and explains implementation steps, field release, and observed impacts such as increased parasitism rates and improved yields. Organisation: INERA, IER,…

  • Biological control of millet head miner using Habrobracon hebetor in the Sahel

    —

    by

    This document presents an agroecological innovation using the native parasitoid Habrobracon hebetor to control the millet head miner (Heliocheilus albipunctella), a major pest causing up to 100% yield losses in the Sahel. The approach involves releasing parasitoids in fields via bags or boxes, reducing pest populations while limiting chemical pesticide use. Implemented across Niger, Mali,…

  • Improved Traditional Cowpea Storage Practices in Burkina Faso

    —

    by

    This document presents an innovation that enhances traditional cowpea storage methods using local materials such as clay, ash, cow dung, and repellent plants. It significantly reduces post-harvest losses caused by insect attacks (previously 40–60%) while preserving nutritional quality, including stable protein content and low aflatoxin levels. The approach combines traditional knowledge with scientific improvements to…
