Interpretive Summary: Entomopathogenic nematodes (also called beneficial nematodes) are environmentally friendly natural bio-pesticides. In this paper we review and analyze the status of using these nematodes as biocontrol agents for orchard pests in North America. In the pursuit of commercial viability, there have been a number of success stories, but also quite a number of dead ends. Some novel targets that are currently being researched include a variety of wood boring insects and weevil pests. Cropping systems that are currently targeted or may be targeted in the near future include (among others) almond, apple, cherry, citrus, peach, pear, pistachio, and pecan. The key will be incorporating the nematodes into feasible pest management strategies. Novel application methods and formulations that are being developed will facilitate incorporation and expanded use of nematodes as microbial control agents. Advances in biocontrol using entomopathogenic nematodes will also be enhanced through fundamental studies on the microbial ecology, epizootiology, and population dynamics of insect pathogens in orchard systems as well as basic studies on host-pathogen relationships.

Technical Abstract: Research and commercial application of entomopathogenic nematodes in temperate orchard systems has a long history. In the pursuit of commercial viability, there have been a number of success stories, but also quite a number of dead ends. In this presentation, we provide insight into the current status as well as new opportunities for entomopathogenic nematodes that are on the horizon. Some novel targets that are currently being researched include a variety of wood boring insects and weevil pests. Cropping systems that are currently targeted or may be targeted in the near future include (among others) almond, apple, cherry, citrus, peach, pear, pistachio, and pecan. The key will be incorporating the nematodes into feasible IPM strategies. Novel application methods and formulations that are being developed will facilitate incorporation and expanded use of nematodes as microbial control agents. Advances in biocontrol using entomopathogenic nematodes will also be enhanced through fundamental studies on the microbial ecology, epizootiology, and population dynamics of insect pathogens in orchard systems as well as basic studies on host-pathogen relationships.
