Antimicrobial Volatiles of the Insect Pathogen .

Fungal volatile organic compounds (VOCs) represent promising candidates for biopesticide fumigants to control crop pests and pathogens. Herein, VOCs produced using three strains of the entomopathogenic fungus were identified via GC-MS and screened for antimicrobial activity. The VOC profiles varied with fungal strain, development state (mycelium, spores) and culture conditions.

Volatile organic compounds of influence the efficacy of entomopathogenic nematodes in insect control.

The entomopathogenic fungus (EPF) occupies the same ecological niche as entomopathogenic nematodes (EPN), with both competing for insects as a food source in the rhizosphere. Interactions between these biocontrol agents can be antagonistic or synergistic. To better understand these interactions, this study focussed on investigating the effect of volatile organic compounds (VOCs), 1-octen-3-ol and 3-octanone, on EPN survival and behaviour.
