研究发现，银针线虫幼虫寄生于白角虫和根毛虫的有翅雌虫（性翅）上。简要介绍了带刺线虫的形态特征。对其中1条线虫的18S rDNA和28S rDNA进行测序，构建贝叶斯系统发育树，在该树上表征了狭缝线虫的寄主范围。我们的研究表明，寄生于性翅果的狭蛾会导致雌性胚胎数量少、体积小。这是与乳虫蚜有关的第一次记录，也是与蚜科有关的第4次记录。
Juvenile mermithid nematodes were found to parasitize winged females (sexuparae) of Eriosoma auratum and Tetraneura radicicola. The morphological characteristics of mermithid nematodes are briefly described. The 18S rDNA and 28S rDNA obtained from one nematode were sequenced and used to construct a Bayesian phylogenetic tree, on which the host ranges of mermithid nematodes were represented. Our study indicated that mermithid parasitism of sexuparae led to fewer and smaller sexual female embryos. This is the first record of a mermithid in relation to eriosomatine aphids and the fourth record with respect to Aphididae.
