摘要
2005年5月,从山东省菏泽市郊区麦田采集土样,分离到褐色和白色胞囊,通过分别对胞囊、2龄幼虫和卵的观察、相关数值测量并拍照,鉴定该种线虫为燕麦胞囊线虫Heterodera avenae Wollenweber,1924.这是首次在山东省发现该种线虫.该种线虫的主要鉴别特征为:胞囊的阴门下桥不明显,泡状突明显,阴门锥双膜孔,阴门裂长度为11.9±1.1(10.5～15.0) μm ;2龄幼虫口针基部球前缘向前突出或平,尾部的透明区较长,长度为44.6±3.3(37.5-54.0)μm,尾末端稍钝.
The soil samples were collected from the wheat field in Heze City of Sandong Province in May,2005, the nematode population was identified as Heterodera avenae Wollenweber, 1924 . This nematode was found in Shandong Province for the first time. The main morphological characters for this nematodee were that： a pair of semifenestra on vulval cone, the vulval underbridge not obvious, bullae obvious, the length of the vulval slit 11.9± 1.1 （10.5-15.0）μm.For the second -stage juvenile（J2）,the style knobs extrude or horizontal anteriorly,the length of tail hyaline portion 44.6±3.3（37.5-54.0）μm,the end slightly blunt.
