Abstract: Non-pathogenic nematodes, such as Bursaphelenchus mucronatus, carried by major pine borer beetles, Monochamus alternatus, Spondylis buprestoides and Arhopalus rusticus in Huangshan Scenic Area were investigated in 2000-2001. Results showed that all the three pine beetles were competent to carry nematode,61.3% of M. alternatus found caring nematode.The largest average number of nematode carried per beetle were found in A. rusticus and M. alternatus, with the number of 5128.6 and 3622.0 and in Wenquan scenic spot and Xihai scenic spot, with average number of 4781 and 10840 for M. alternatus and A. rusticus respectively. Time dynamic of the nematode carried by beetles and the relationships between genital, body size and the number of nematode carried were also discussed.
