Abstract: Objective To investigate the species of Limacodidae and the biological habits on Prunus cerasifera and sycamore in the urban area of Wuhu City， so as to provide the reference for the prevention and control of the diseases caused by Limacodidae. Methods Two observation places were selected in the urban area of Wuhu City， and the survey period of the first observation place （A） was from 2014?5?4 to 2014?11?2， and eucleid caterpillar was observed and collected every Sunday （a total of 27 times）； the survey period of the second observation place （B） was from 2014?1?5 to 2014?12?28， and eucleid caterpillar was observed and collected every Sunday （a total of 52 times）. The eucleid caterpillars were collected by the visual inspection and artificial direct collecting method， and then they were identified and classified by the naked eye direct observation and the direct observation with the help of the anatomical lens in the laboratory. Results There were seven kinds of identified Limacodidae from the two observation places and their occurrence regularity， the species composition ratio， and natural enemies were understood. Conclusions Limacodidae larvae not only are the defoliator of the ornamental forests， but also harm the health of residents， that is they can cause eucleid larva dermatitis. Therefore， we should strengthen the prevention and control of Limacodidae， reducing its impact on the lives of the residents.

摘要： 目的 调查芜湖市区红叶李和悬铃木常见刺蛾种类及其生活习性，为防治其引起的疾病提供科学依据。方法 在芜湖市选取2个观测点（A点和B点），2014?5?4-2014?11?2为A观测点调查时段，每逢星期日观测和采集刺蛾幼虫1次，共27次。2014?1?5-2014?12?28为B观测点调查时段，每逢星期日观测或采集刺蛾幼虫1次，共52次。采取目测人工直接采虫法将刺蛾幼虫采集入瓶带回实验室，肉眼直接观察和借助解剖镜直接观察刺蛾幼虫的形态特征，进行虫种鉴定和分类。结果 经鉴定，在芜湖市2个观测点采集的刺蛾共有7种，并了解了它们的发生规律、虫种构成比和幼虫天敌。结论 刺蛾幼虫不但是危害观赏林木的食叶害虫，同时也可危害居民的身心健康，引起刺蛾幼虫皮炎，应加强对刺蛾的防制，降低其对居民生活的影响。
