Biological characteristics of the almond moth, Cadra cautells, of which eggs will be substitute diets for Orius spp. and Trichogramma spp., were investigated and a mass-rearing system for the moth was developed. At 25¡É, egg , larval, and pupal period was 4.2, 29.8 and 8.3 days, respectively, The moth could be successfully reared with all food substrates tested, of which rice bran(50%)+chick feed(50%) assumed to be proper for mass-rearing in view of cost. Eggs could be stocked at 9¡É for 7 days, representing 82% hatchability. In the rearing cage used, 1,000 eggs was better for initial level of inoculation, showing relatively high emergence rate and adult weight. Mass-rearing procedures were explained in detail.
