A Review on the Role of Entomopathoenic Nematodes (EPNs) in Controlling Agricultural Insect Pest

Belay Feyisa

Billions of dollars are spent annually throughout the world to control and prevent Agricultural insect pest. Many bacteria, fungi, and nematodes occurring naturally in soils are known to suppress Agricultural insect pest activity. Entomopathogenic nematodes (EPNs) and their associated bacterial symbionts are highly specific in their host range and compatible with many pesticides. EPNs, also called beneficial nematodes, are commercially used to control insect pests. These nematodes offer an environmentally safe alternative to chemical insecticides, and a wide range of EPNs are effective against various Agricultural insect pests. Are soil parasites that infect different types of arthropods e.g. termites, larva of butterflies, moth, beetles and grasshopper thus affecting them in various ways. They have been utilized in classical, conservation, and augmentative biological control programs. The vast majority of applied research has focused on their potential as inundatively applied augmentative biological control agents. This is through reducing their fertility or causing sterility, delaying development and shortening longevity of the arthropods. In this review, the role of EPNs in controlling Agricultural insect pest, the current merits and limitations is summarized.
