In this paper, the aseptic eggs of Bursaphelenchus xylophilus were obtained after treated with 30% H202, and cultured with Pinus thunbergii callus. Ten B. xylophilus-carrying bacterial strains directly isolated from diseased P. thugbergii and P. massoniana in six epidemic provinces i.e., GcM6-2A Pseudomonas putida, GcM6-1A P. putida, ZpB1-2A P. putida, HeM2A Pseudomonas sp., HeM1A Pseudomonas sp., HeM142B Pseudomonas sp., GcM1-3A P. cepacia and HM3 Pantoeu sp., ZpB4-2B Staphylococcus sciuri and ZpB2-3A Enterobacter amnigenus, were collected, and the effects of axenic B. xylophilus (ABx) on their propagation were studied. The results showed that pine wood nematode (PWN) promoted the propagation of 7 bacterial strains in Pseudomonas and 1 bacterial strain in Pantoeu sp., including Pseudomonas putida, P. putida, P. putida , Pseudomonas sp., Pseudomonas sp., Pseudomonas sp., P. cepacia and Pantoeu sp., but inhibited Staphylococcus sciuri and Enterobacter amnigenus, which could explain the phenomenon that Pseudomo
