Pests and their parasitoid wasps associated with stored products were surveyed from 2006 to 2007 in the urban area suburb of Mashhad. Seventy-four samples from several cereals, dried fruits, legumes and processed food products were collected in 10 locations. A total of 11 insect pest species from 5 families in 2 orders, Coleoptera and Lepidoptera were recorded. Among them, the Cowpea weevil, Callosobruchus maculatus (Fabricius), (Col.: Bruchidae) and the Indian meal moth, Plodia interpunctella (Hubner) (Lep.: Pyralidae) were the most abundant species. The Rust-red flour beetle, Tribolium castaneum (Herbst) (Col.: Tenebrionidae), and the Sawtoothed grain beetle, Oryzaephilus surinamensis (L.) (Col.: Silvanidae), were the most numerous and widely distributed species sampled in the rest of food products. We found 5 species of parasitoid of storage pests recruiting from insects: Habrobracon hebetor (Say) (Hym.: Braconidae), Cephalonomia tarsalis (Ashmead) (Hym.: Bethylidae), Anisopteromalus calandrae (Howard) (Hym.: Pteromalidae), Theocolax elegans (Westwood) (Hym.: Pteromalidae), and Venturia canescens (Gravenhorst) (Hym.: Ichneumonidae). The occurrence of parasitoid attacking stored product pests indicated their potential for biological control in Mashhad stores.
