Parasitoids applied in the storage environment include Anisopteromalus calan-dreae, where two to three releases at nine-day intervals of the parasitoid at 10 x the density of the prey, Sitophilus oryzae were recommended (Smith, 1994). Choetospila elegans has also been applied against S. oryzae (Williams and Floyd, 1971), while Bracon hebetor and Trichogramma pretiosum (Brower and Press, 1990) have been used against Ephestia cautella and Plodia interpunctella, and Ventura canescens against only the former host.
