摘要
1984～1985年,在黑龙江省伊春带岭地区的落叶松人工林和种子园内,发现有两种叶蜂幼虫混合危害,幼虫体均为绿色,很难区别。为弄清其种类,进行了室内群体和个体饲养观察。经鉴定为魏氏锉叶蜂和落叶松锉叶蜂,系国内新记录。现将形态和生物学特性及其区别记述如下。
This paper describes two species of sawfly, Pristiphora wesmaeli Tischbein and P. lands (Hartig), in Bailing, Hei-Longkiang Province, which are new records in China. According to the field observation, P. wesmaeli has one or two generations a year, but in the laboratory, three generations a year in parthenogenesis.
