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。
Diplolepis rosae (L.) Originated in North America and found for the first time in China. The invasive alien species in Rosa serrata × R.Rugosa in Gansu Province caused huge economic losses. This article mainly introduced the morphological characteristics of this kind of young, adult and their insects, and compiled the retrieval table of this kind of relatives. At the same time, Torymus bedeguaris (L.), one of the natural enemies of this species, was found and its parasitism rate was investigated. The results showed that the long-tailed wasp can effectively control the population growth.
