抄録

The unequivocal induction of precocious metamorphosis was demonstrated by dietary administration of 1-citronellyl-5-phenylimidazole (KK-22) in the 4th instar silkworms, Bombyx mori, and was observed in response to doses: 100% activity at 25-100ppm, 62.5% at 12.5ppm, and 6.3% at 6.25ppm. Precocious pupation induced by KK-22 always occurred with prolongation of the 4th larval stage. The weights of the precocious cocoon and cocoon shell were about 1/2 and 1/3 of those in normal silkworms, respectively. The pupal molt was not influenced by KK-22. In contrast to precocene I and II, KK-22 induced distinct precocious metamorphosis in the silkworm without any antifeedant and lethal effects and inhibition of larval growth.
