Abstract:In simulated warehouse rooms, single release of 50 pairs of the parasitic wasp, Anisopteromalus calandrae (Howard), in 8,250 g of scattered wheat infested with ca. 1,500 rice weevils, Sitophilus oryzae (L.), resulted in 76.1% suppression. Small bags of cotton, burlap, and woven polypropylene containing 275 g of infested wheat retarded the ingress of A. calandrae, because none of the cotton bags and only 30.0 and 47.0% of the burlap and polypropylene bags, respectively, contained parasitized weevils. Overall, 12.9 and 18.7% of the S. oryzae populations were suppressed in burlap bags and polypropylene bags, respectively. However, when only bags containing parasitized weevils were considered, suppression averaged ca. 55% in the burlap and 49% in the polypropylene. A. calandrae significantly reduced the number of S. oryzae emerging from scattered infested wheat, thus protecting uninfested wheat inside cotton, burlap, and polypropylene bags placed adjacent to the infested wheat.
