通辽市黄褐天幕毛虫生物学特性的初步研究

A Preliminary Study on Biological Characteristics of Malacosoma neustria testacea Motschulsky from Tongliao

黄褐天幕毛虫在我国广泛分布,是园林绿化树、果树及人工林的重要害虫.2009～2010年对通辽市黄褐天幕毛虫的生物学特性进行了野外和室内观察.结果表明:在通辽市该虫一年发生一代,卵期约290天,幼虫共6龄,幼虫期43天左右,蛹期10～15天,成虫期2～7天.

Malacosoma neustria testacea Motschulsky is widespread in China.It damages landscape trees,fruit trees and plantation.We studied biological characteristics for Malacosoma neustria testacea from Tongliao using the method of field and laboratory observation in the 2009 to 2010.The results showed that M.neustria testacea of Tongliao took place one generation in a year and the larvae of it had six instars,about 43 days,290 day as egg stage,10 to 15 days as pupae,2 to 7 days as adult.
