Interpretive Summary: Insect-killing nematodes are environmentally friendly biopesticides that are used to control a variety of economically important pests. Post-application survival of these nematodes is a key factor affecting field efficacy. Formulation and application technology can play a major role in determining survivability. Various formulations have been developed for soil application; a number of these are currently in use. The utility of entomopathogenic nematodes may be expanded through some recently developed formulations that offer greater potential for survival in above-ground applications such as in greenhouses. Formulation or application of nematodes in their infected hosts may also offer opportunities for enhanced survival. Additionally, entomopathogenic nematode species or strain selection can have considerable impact on post-application survival.

Technical Abstract: Post-application survival of entomopathogenic nematodes is a key factor affecting field efficacy. Formulation and application technology can play a major role in determining survivability. Various formulations have been developed for soil application; a number of these are currently in use. The utility of entomopathogenic nematodes may be expanded through some recently developed formulations that offer greater potential for survival in above-ground applications. Formulation or application of nematodes in their infected hosts may also offer opportunities for enhanced survival. Entomopathogenic nematode species or strain selection can have considerable impact on post-application survival. Indeed in recent laboratory experiments conducted in soil, we observed substantial variation in survivability of more than 20 entomopathogenic nematode strains and species.
