[Note] Artificial Diet for Mass Rearing the Emma Field Cricket, Teleogryllus emma (Orthoptera: Gryllidae)

were reared on several types of artificial diets. The development period of nymphs were 55.4 days when only a single food, wheat bran, was provided, and it did not show a significant difference compared to the rearing results of the Danong diet and mixed diet. The supplying period of fish meal as the animal feed, the high emergence rates were obtained at 3rd instar with 90 % and 4th instar with 100%. For the added amount test, when more than 40 % of the diet was added, it confirmed that the insect weight increased. The char-acteristics of development according to each added amount of the vegetable food (dry bean-curd residue and corn powder) were investigated to minimize the dangers of the degeneration of diet when rearing with a single feed during the 1st ~3rd instar period. First, as the added amount of bean-curd residue increased, nymphal development period became longer and the emergence rate became low. With corn powder as the single diet, all died before becoming adult. However, when corn powder was added up to 30%, no differ-ence existed in the breeding results
