Synergistic actions of symbiotic bacteria modulate the insecticidal potency of entomopathogenic nematode Steinernema monticolum KHA701.

ABSTRACT: Entomopathogenic nematodes (EPNs), primarily Steinernema and Heterorhabditis, form symbiotic relationships with bacteria from the genera Xenorhabdus and Photorhabdus, respectively. These bacteria exhibit insecticidal activity and suppress competing microorganisms, allowing EPNs and their symbionts to dominate insect cadavers. While monoxenic associations are fundamental to EPN-bacteria interactions, recent studies suggest that EPNs may harbor a diverse array of symbiotic bacteria with consistent associations. However, the role of these additional symbiotic bacteria in EPN pathogenesis and the complexity of their interactions remain unclear. In this study, Steinernema monticolum KHA701 was newly isolated using the Galleria mellonella bait method. Compared to the highly pathogenic Heterorhab
