中文摘要: 自1990年代中期起,北京市门头沟区小龙门林场等地的华北落叶松 (Larix principis-rupprechtii Mayr) 遭受一种扁叶蜂的危害,不少年份成片的落叶松针叶被食。因雌蜂的触角节数与国内的文献资料不符,该种一直没有鉴定到种。本研究鉴定该种为落叶松腮扁叶蜂Cephalcia lariciphila (Wachtl),对各虫态进行描述并提供彩色图片,最后提出了防治策略,以利用黄绿色胶带诱杀成虫和人工挖除入土的预蛹和蛹为主,以保护作为水源地的生态环境。
英文摘要: Since middle of 1990’s, a pamphiliid sawfly became a new pest at Xiaolongmen Forest Farm in Mentougou District of Beijing, with frequently heavy defoliation on the larix (Larix principis-rupprechtii). Now it is determined to be the web spinning larch sawfly, Cephalcia lariciphila (Wachtl, 1898). The present paper described morphology of adult, egg, larva and pupa, provided with color pictures. The control strategies should put emphasis on application of yellowish green sticky traps for adults and artificial control measures for the eonymphs and pupae.
