Experiment of using difluron for molt-delaying on the adults of Curculio davidi fairmaire of the che

摘要: 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.

Abstract: The longest molt-delaying time of Curculio davidi fairmaire adults insects in chestnut plantation in south of Henan province for using difluron can be obtained under the following conditions,air humidity 95%,wind velocity less than 2 m/s and photosynthetic rate 350 lx or air humidity 95%,wind velocity less than 2 m/s and photosynthetic rate 200 lx.
