Investigation on species of Limacodidae on Prunus cerasifera and sycamore in urban area of Wuhu City

Abstract

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. 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. 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. 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.
