Some biological effects of anti-juvenile hormone active compound, 1-citronellyl-5-phenyl-imidazole (KK-22), on the 3rd instar silkworm, Bombyx mori L., were investigated by feeding treatment with artificial diet for successive days of the 3rd instar period. Drastic precocious metamorphosis was induced in response to doses of KK-22 : 100% at 50-200 ppm, 95% at 25 ppm, and 45% at 12.5 ppm in the diet. Some 3rd instart larvae ingesting diet containing 50 to 200 ppm of KK-22 were metamorphosed to pupae within the same instar stage; they spun to make cocoons and pupate, but failed in adult emergence. The larval development of the treated 3rd instar silkworms was prolonged for 1 to 5 days, accompanied by a gain of body weight exceeding the controls. The induction of precocious metamorphosis seems to correlate with prolongation of the larval developmental period in the 3rd instar.
