Abstract: As an important natural enemy of longicorn beetles, Dastarcus helophoroides has been widely used for biological control in China, especially in control of the most important vector of Bursaphelenchus xylophilus, Monochamus alternatus. In the long-term coevolution with different species of longicorn beetles in the wild, D. helophoroides has evolved into different biotypes. Overwintering adults of D. helophoroides were found on the infected trees in the epidemic area of pine wood nematode in Fushun, Liaoning Province. Through morphological comparison and biological characteristics observation, the D. helophoroides was determined as the biotypes of Monochamus saltuarius, which was the first report of D. helophoroides as a natural enemy of M. saltuarius in China. This finding can drive the control of vector of pine wood nematode in northern China.

Key words: Dastarcus helophoroides, Bursaphelenchus xylophilus, Monochamus saltuarius, biological control
