Basic and Applied Research: Entomopathogenic Nematodes

Abstract Entomopathogenic nematodes in the genera Heterorhabditis and Steinernema kill arthropods with the aid of their bacterial symbionts. These nematodes are potent microbial control agents that have been widely commercialized for control of economically important insect pests. Biocontrol efficacy relies on both abiotic and biotic influences and can be enhanced through improving the nematode strain and stability of beneficial traits; through production, formulation, and application technology; or through environmental manipulation. Advances in these areas are poised to expand the utility of entomopathogenic nematodes in various cropping systems.
