用灭幼脲3号作了延迟栗实象甲成虫蜕皮的试验.试验结果表明,25%的灭幼脲3号胶悬剂在空气湿度95%、风速小于2 m/s、光照强度为350 lx和25%的灭幼脲3号胶悬剂在空气湿度90%、风速小于2 m/s、光照强度为200 lx的条件下延迟蜕皮时间最长. The experiment of delaying molting of adult chestnut of Actuate Tricholoma were carried out with diflubenzuron 3. The test results showed that 25% of diflubenzuron No.3 suspending agent had good air humidity of 95%, air velocity less than 2 m / s and light intensity of 350 lx and 25% diflubenzuron No.3 suspension showed the longest delay in molting under air humidity of 90%, wind speed less than 2 m / s and light intensity of 200 lx.
