Two propanoate units (see Fig. 2) seem to be coupled in 1-ethylpropyl (2S,3.R)-2-methyl-3-hydroxypropanoate 221, the male produced aggregation pheromone of the granary weevil, Sitophilus granarius [390-393]. Even the ester-moiety may origin from two propanoate units after decarboxylation and reduction Three propanoate units (and decarboxylation, see Fig. 2) may produce (4S,5 )-5-hydroxy-4-methyl-3-heptanone, sitophilure 222, the aggregation pheromone of the rice weevil, Sitophilus oryzae [394, 395]. The same carbon skeleton is present in the achiral 4-methylheptan-3,5-dione 223, the pheromone of the pea weevil, Sitona lineatus [396-398]. 

Synthesis of the aggregation pheromone of the rice weevil Sitophilus oryzae and the maize weevil S. zeamais, (+)-sitophilure, was achieved in two steps using NADPH-dependent ketoreductases. ... 

Blrk and Applebaum (41) have studied the adverse effects of soybean trypsin inhibitors on development and protease activity in Tribolium castaneum. In Sitophilus oryzae, high doses of soybean trypsin inhibitor caused adult mortality (42). The wound-induced accumulation of these inhibitors is discussed by C. A. Ryan elsewhere in this symposium.

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.
