Scent of death: Emission and behavioral role of 1-nonene in entomopathogenic nematode Steinernema kraussei.

ABSTRACT: Entomopathogenic nematodes (EPNs) provide a natural alternative to synthetic pesticides for pest control. Understanding how EPNs respond to volatile cues including those released by infected cadavers is crucial for determining the behavior control necessary for improving their effectiveness. In this study, we tested the response of Steinernema kraussei, a cruiser foraging species, to 1-nonene. Additionally, we analyzed the emission dynamics of this compound from Galleria mellonella larvae infected by three different EPN species: S. kraussei, S. carpocapsae, and S. feltiae. Concentrations of 1-nonene at 20 mM and above elicited a repellent behavior in S. kraussei. Ethanol, used as a solvent for 1-nonene, was attractive to this EPN at high concentrations only. The emission of 1-nonene was th
