The differences in a-glucosidase inhibitory activities among several strains of the silkworm, Bombyx mori which were reared in Tokyo University of Agriculture and Technology was discussed. The inhibitory activity of silkworm (Koishimaru; 5th instar larvae) was significantly higher (p<0.01) than that of mulberry leaves (Minamisakari) which was used as feed. The inhibitory activity of silkworm powder was also significantly higher (p<0.01 ) than that of mulberry powder. The inhibitory activities of eight strains of the silkworm were measured. The inhibitory activity of Koishimaru (4th instar larvae) was higher than those of other strains of larvae in 4th and 5th instar. Furthermore, between the same strains, we found that the inhibitory activity of 4th instar larvae was higher than that of 5th instar expect Aburako. On the other hand, we also investigated the a-glucosidase inhibitory activities at different stages in C 108 and J 601 strain. 3 rd instar larvae of C 108 was significantly higher (p<0.01 ; 2 rd; <0.05) than other instar larvae and pupa. 3 rd instar larvae of J 601 was also higher (4th;p<0.05; 5th;p<0.01) than 4th and 5th instar larvae. sup(1)Faculty of Agriculture, Tamagawa University, Tamagawa-gakuenn, 6-1-1, Machida, Tokyo 194-8610, Japan, and sup(2)Faculty of Agriculture, Tokyo University of Agriculture and Technology, Saiwaicho 3-5-8, Fuchu, Tokyo 184-8509, Japan
