The objectives of writing this book were to assist fellow Students and Researchers on the potentials of some plant products (Khaya senegalensis A. Juss. and the Azadracta indica A. Juss. seed oils)in the management of cowpea pests (Maruca vitrata Fab. and Clavigralla tomontosicollis Stal.) in the Northern Guinea Savanna. Thus, it contributes to the management of these pests and enhance the adoption of Integrated Pests Management (IPM)strategy in order to reduce the risks involved (cost and environmental degredation) as well as their application frequencies.
