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。
Objective To investigate the species and life habits of the common moths and their living habits in Honghu pluvialis and Platanus acerifolia in Wuhu City and provide a scientific basis for the prevention and treatment of the diseases caused by them. Methods Two observation points (point A and point B) were selected in Wuhu city. 2014-5-4-2014-11-2 was the observation period of observation point A. The larvae of the larvae were observed and collected once a week for 27 times . 2014-1-5-2014-12-28 During the survey period of observation point B, the larvae of the larvae were observed or collected once a week for 52 times. Artificial direct artificial insects were taken to collect the larvae of the larvae in the lab and the larvae were taken back to the laboratory. The morphological features of the larvae of the larvae were observed directly with the naked eye and the morphological characteristics of larvae of the larvae were observed with the help of a dissecting microscope. Results A total of 7 species of moths were collected from 2 observation sites in Wuhu City, and their occurrence patterns, proportion of insect species and predators of larvae were studied. Conclusion The larva of the moth larvae is not only a leaf-eating pest that damages the ornamental trees, but also can endanger the physical and mental health of the residents and cause the larvae of the larvae. It should strengthen the control of the larva and reduce its impact on the residents’ life.
