Living and freeze-killed natural and laboratory hosts with a different level of susceptibility to entomopathogenic nematodes were exposed to the larvae of S. affine and S. kraussei in two different experimental arenas (Eppendorf tubes, Petri dishes) and the success of the colonisation and eventual progeny production were observed. The results shown that by scavenging EPNs can utilize cadavers of insects that are naturally resistant to EPN infection and so broaden their host range. Possible mechanisms of the insect resistance to EPNs are discussed.
