Abstract
Two bacterium isolates were isolated from the body of pine wood nematode(Bursaphelenchus xylophilus):strain GD1 and R,and GD1 was identified as the species Bacillus firmus.The one or two-yearold solution cultured excised branches of Pinus massoniana were inoculated with disinfected Bursaphelenchus xylophilus(Bx),GD1,R,Bx+GD1 and Bx+R,respectively.The results showed that by inoculation with the mixture of Bx and B.firmus,the branches were diseased,the oleoresin exudation of the branches decreased or ceased,and the transpiration of the branches reduced,while by inoculation with Bx or B.firmus singly,the branches were not diseased.Stain R had no effect on the occurrence of pine wood nematode disease.Therefore,it was proposed that the pine wood nematode and its accompanying bacterium were both necessary pathogenic factors of the pine wilt diseases.
