Abstract
Stored product pests are responsible for losses that can amount 10% during cereal storage in the world. Aiming to find an alternative method to the chemicals used for the stored-product pests, eight strains of entomopathogenic nematodes (EPNs) were tested against five species of stored product pests. The bioassays were conducted in microtubes containing paper, inoculated with EPNs and insect diet. All the insect species were susceptible to the EPNs strains. Anagasta kuehniella and Tenebrio molitor larvae and Acanthoscelides obtectus adults were highly sensitive to the higher doses with most species and/or strains of EPNs. Adults of Sitophilus oryzae and Sitophilus zeamais were relatively less sensitive to all EPNs. Therefore, EPNs show as potential control agents for stored products pests in prophylactic applications in warehouses.
