Semiochemicals Enhancing Entomopathogenic Nematodes’ Efficacy in Pest Management

Entomopathogenic nematodes (EPNs) in the families Steinernematidae and Heterohabditidae are commonly used as biological control agents in pest management programs. EPNs can reduce grower reliance on conventional insecticide applications and are not considered to negatively impact the ecosystems in which they are deployed. Recent advances in the ability of semiochemicals to enhance the efficacy and consistency of commercial EPN strains may encourage wider adoption of EPNs in integrated pest management programs. This chapter highlights the role of biochemical stimuli in EPN ecology and discusses their potential to increase nematode dispersal, survival, and infectivity of target pests, ultimately enhancing their effectiveness as a biocontrol agent.
