Crop pest management and food security in Nigerian agriculture

Abstract

Pests damage crops at different stages of growth on the field, at harvest, during transportation and in storage. This leads to 5 – 40% crop loss yearly and has a serious effect on the food security for the ever-increasing population of the country. The management of pests in crops to obtain a better yield is paramount for food security. The resource-poor farmers who produce a large percentage of the crop for consumption cannot afford expensive management of pests in order to meet the yearly target consumption level for the country. The different methods for the management of pests—cultural, biological, indigenous knowledge systems, use of resistant varieties, use of plant extracts, use of pheromones and the minimal use of chemicals in an integrated pest management system which hitherto existed as fragmented information—are discussed. Areas for future research are also mentioned.
