本文报道应用抗保幼激素生理活性物质“抗11”调控家蚕生长发育的初步试验结果。从3龄饷食开始,连续添食300～500ppm药液48小时;或以400～500ppm的药液浓度给4龄起蚕连续添食48小时,3眠蚕诱发率可达100％。3龄或4龄添食,当龄历期延长,但全龄历期均比对照区缩短,如4龄添食区缩短近5日,所诱发的3眠蚕能结茧、化蛹、羽化、交配、产卵,所结的茧小,量低,纤度变细。 This paper reports the application of anti-juvenile hormone physiologically active substances “anti-11” to control the growth of silkworm preliminary test results. From the age of 3 races, continuously add 300 ~ 500ppm liquid 48 hours; or 400 ~ 500ppm concentration of liquid to the 4th instar silkworm continuously add 48 hours, 3 sleepworm inducing rate of up to 100%. The 3rd instar or 4th instar larvae fed on the same day, while the period of the same age was prolonged, but the period of the full age was shorter than that of the control. For example, the 4th instar larvae were shortened nearly 5 days, , Mating, spawning, the small cocoon, low volume, fineness thinner.
