中文摘要： 玫瑰犁瘿蜂Diplolepis rosae (L.) 原产于北美地区，首次在中国发现。该外来入侵种在甘肃地区危害苦水玫瑰（Rosa serrata ×R. Rugosa），造成巨大经济损失。本文主要介绍了该种幼期、成虫及其虫瘿的形态特征、编制该种近缘种的检索表。同时，发现该种的天敌之一——玫瑰瘿长尾小蜂Torymus bedeguaris (L.)，并对其寄生率进行了调查，结果表明该长尾小蜂可有效控制种群数量的增长。
英文摘要： Diplolepis rosae (L.), originating from North America, is recorded for the first time in China. This pest infested Rosa serrata ×R. rugosa, causing heavy economic losses in Gansu Province. In this paper, the morphologies of the larvae, adult and gall of Diplolepis rosae (L.) are described, and a key to related species is provided. At the time of discovery and identification of D. rosae, one of its natural enemies, Torymus bedeguaris (L.), was also discovered, and the parasitism ratio surveyed. The results indicate that this parasitic wasp can effectively control the population growth of D.rosae.
