The third stage of Infective juveniles (IJs) habitually traces suitable hosts when the insects feed, through chemical cues produced from plant roots damaged by herbivores. EPNs are attracted to CO2 and volatile substances emitted by soil insects and plant roots. Besides, other chemical mixtures, belonging to diverse chemical categories persuade chemotaxis in nematodes. Multitrophic interactions that use and exchange this chemical information play key role in protection of plant and predator-prey mechanics in the chemical ecology of EPNs.
Various protocols are examined to study the complexity of adaptations in a chemical ecology of a chemically mediated tritrophic interactions among plants, insects and nematodes.
