Insect Defense System and Immunosuppression Strategies of Entomopathogenic Nematodes - An Overview

Studies on host-parasite interaction and immune responses in insects will greatly benefit human health from biocontrol point of view. Role and relationships between insect hosts and entomopathogenic nematodes are elaborated where the efficacy of the entomopathogenic nematodes depends on the stability between the parasitic strategies and the immune response of the host. Entomopathogenic nematodes are potential biocontrol agent. The cellular and humoral responses are avoided by the nematode-bacterium complexes by producing immunodeficiency in insects. The review outlines the mechanisms of immune recognition and defense of insects as well as immune evasion strategies of Entomopathogenic nematodes (EPNs).
