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.
