Activity of eight strains of entomopathogenic nematodes (Rhabditida: Steinernematidae, Heterorhabditidae) against five stored product pests

All the insect species were susceptible the EPNs strains. Anagasta kuenhiella and Tenebrio molitor larvae and Acanthocelides obtectus adults were highly sensitive to the higher doses of the majority of the species and/or strains of EPNs. Sitophilus oryzae and Sitophilus zeamays adults were relatively less sensitive to all the EPNs. Therefore, EPNs show themselves potential agents of control of these insects in prophylactic applications in the warehouses.
