Biorational control methods for protection of stored grain legumes against bruchid beetles

Abstract

Bruchid beetles such as Callosobruchus maculatus are known to the storage pests of grain legumes and cause tremendous damage. The main method to protect from them is chemical insecticides or fumigants. But, they would cause some problems such as environmental pollution, hazard to health. So, it is necessary to develop the grain legumes protection methods or systems using less chemical insecticides or fumigants from the perspective of integrated pest management (IPM). In this paper, I review the works of legumes grain protection methods without chemical insecticides or fumigants especially for the natural parasitoids, essential oils and other methods recently developed.
