To develop an efficient mass rearing system for Cadra cautella(Walker) and Orius laevigatus(Fieber) were investigated under the conditions of photoperiod 16L : 8D, 70±5% RH and 23±2℃. The highest efficiency rate(multiply 28.6) of C. cautella was achieved when using the rearing cage of 20ℓ than 3ℓ. The highest efficiency rate(multiply 16.3) of O. laevigatus was achieved when using the rearing cage of 5ℓ (adult 1,500, 10 pcs(10 cm) of plant of egg taking). The moth could be successfully reared with all food substrates tested, of which rice bran(43%) + chick feed(43%) + yeast(14%) assumed to be proper for mass-rearing in view of cost.
