Monochamus urussovii is a vector of Bursaphelenchus xylophilus in China
Monochamus urussovii (Coleoptera: Cerambycidae – EAEU A2 List) is a known vector of the nematode Bursaphelenchus mucronatus. Experiments conducted in 2022 in Jilin province (northeast China) confirmed that it can also vector Bursaphelenchus xylophilus (EPPO A2 List) in Pinus koraiensis.
Bursaphelenchus xylophilus was isolated from adult M. urussovii specimens that had emerged from dead P. koraiensis in a forest affected by pine wilt disease. Transmission experiments were also conducted on 6-year-old P. koraiensis plants and showed that M. urussovii transmitted the nematode.
