- Title:

- Keywords:
- Ditylenchus; Ditylenchus dauniae Brzeski &; Palmisano (1990); China
- 摘要:
- 茎线虫属（Ditylenchus）的线虫是植物的一类重要病原物，本研究从中国东北地区大豆根围土壤中分离到1种茎属线虫，利用光学显微镜观察线虫的形态特征，对其进行鉴定。结果显示：分离到的茎属线虫经鉴定为道尼茎线虫（Ditylenchus dauniae Brzeski & Palmisano，1990），为我国迄今为止尚未报道的新纪录种。其主要鉴定特征：侧区6条侧线；后阴子宫囊长32.0~57.0 μm，为阴门处虫体直径的0.9~2.6倍；阴门靠后；交合伞覆盖尾长的31%~52%。
- Abstract:
- Ditylenchus is a kind of important plant pathogens. In this study, a new record species of Ditylenchus was isolated from soybean rhizosphere soil in Northeast China. The morphological characteristics of the nematode were identified by optical microscopy. The results showed that the isolated stem nematode was identified as Ditylenchus dauniae Brzeski & Palmisano (1990), a new record species in China. The main identification features were as follows: 6 lateral lines in the lateral area; the length of the posterior scrotum uterine sac was 32.0-57.0 m, 0.9-2.6 times the diameter of the insect body in the vagina; the posterior part of the vagina, and the length of the cross umbrella covered 31%-52% of the tail length.
