We report the occurrence of Lysiphlebus orientalis in Serbia, an aphid parasitoid from the Far East that is new to Europe and has the potential to become invasive. Our finding based on morphological characters is confirmed by analyses of mitochondrial cytochrome oxidase subunit I sequences. An increase in number and an expansion of the host range were observed during field studies over the past two years, and it is determined that the current host range encompasses nine aphid hosts on 12 different host plants, forming 13 tri-trophic associations. A host range determined for European populations of L. orientalis appears wider compared with that in its Far Eastern native habitats where Aphis glycines Mats. is the sole known host. Moreover, it overlaps considerably with the host ranges of European parasitoids that play an important role in the natural control of pest aphids.
我们报告了东方蚜小蜂在塞尔维亚的出现，这种来自远东的蚜虫寄生蜂对欧洲来说是新物种，并且有可能成为入侵物种。我们基于形态特征的发现通过线粒体细胞色素氧化酶亚基I序列分析得到了证实。在过去两年的田间研究中观察到其数量增加且寄主范围扩大，并且确定目前的寄主范围包括12种不同寄主植物上的9种蚜虫寄主，形成了13种三营养关联。与在其远东原生栖息地相比，欧洲东方蚜小蜂种群的寄主范围似乎更广泛，在远东原生栖息地，大豆蚜是唯一已知的寄主。此外，它与在害虫蚜虫自然控制中起重要作用的欧洲寄生蜂的寄主范围有相当大的重叠。
