Title: The relationship between substance on the pine wood nematode body surface and bacteria carried by the nematode
Abstract: Pine wilt disease was complex infection caused by pine wood nematode(Bursaphelenchus xylophilus),and bacteria.Studying the relationship between B.xylophilus and bacteria may provide evidence for the pathogenic mechanism of pine wilt disease.To clarify the relationship,the bacterial strains were inoculated to marinade on different aseptic B.xylophilus surface body surface,and cultured aseptic B.xylophilus after added the bacteria was to the B.xylophilus suspension.The results showed that the reproduction of bacteria was stimulated by the marinade of B.xylophilus body surface,B.xylophilus numbers increased more rapidly with bacteria present than without bacteria.This revealed that the reproduction and growth of B.xylophilus was also promoted by the bacteria.In conclusion,B.xylophilus and the bacteria benefited each other.Experiments were also designed to investigate the tropism test of aseptic B.xylophilus and bacteria,and test the specificity between the B.xylophilus and bacteria it carried.The results indicated that the bacterial strain of P.agglomerans or the bacterial strain mixed with P.agglomerans had obvious taxis towards all isolates of aseptic B.xylophilus.Experiments also tested the specificity between the B.xylophilus and bacteria it carried.The results showed that the aseptic B.xylophilus has no taxis towards the bacteria it carried,and that there was no obvious specificity taxis to the B.xylophilus with the bacterial strains it carried.
