Abstract: Water content, pH and microbe diversity of Anoplophora glabripennis(ALB) ovipositing slits in 5 tree species in Beijing and Ningxia were investigated. The results were listed as follows: In the two regions, water content of ALB oviposition slits at middle stage was highest, and was even higher than that of healthy bark in the same time. Water content of ALB oviposition slits was intermediate at later stage and was lowest at early stage. pH of ALB oviposition slits was alkalescent (7.88～9.98) and higher than that of healthy bark (6.06～7.10). There were 473 fungi strains isolated from oviposition slits, and they belong to 12 genera, amog which 8 species were identified. Moreover Fusarium was the dominated genus in the two regions. Fungi population isolated from oviposition slits were more than that of healthy bark. In Beijing, diversity index (H), richness index(S) of oviposition slits were higher than that of healthy bark. In Ningxia, the result was reverse. As for bacteria, Xanthomonas and another unidentified strain were the main isolates. Additionally, Serratia marcescens, a kind of insect pathogen, was found in Salix matsudana. Only one kind of actinomycete was isolated and identified as Streptomyces sp.
