摘要/Abstract

摘要： 研究北京和宁夏两地5个树种上光肩星天牛刻槽含水量、pH值及微生物多样性。结果表明: 两地的刻槽中期含水量最高,且高于同期健康树皮,晚期次之,早期最少。刻槽的pH值(7.88～9.98)均偏碱性,高于健康树皮pH值(6.06～7.10)。两地的刻槽共分离到真菌12属、473株菌株,8种鉴定至种级;优势属为镰刀菌属,刻槽真菌数量多于健康树皮。宁夏各树种刻槽真菌多样性指数(H)、丰富度指数(S)比健康树皮高,北京各树种刻槽H,S低于健康树皮。两地各树种刻槽内细菌群落种类大致有2种,为黄单胞杆菌属细菌和白色未定名细菌,此外,北京旱柳刻槽内分离到黏质沙雷氏菌,该菌是一种昆虫致病菌。刻槽内放线菌只分离到1种,为链霉菌属放线菌。

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.

Key words: Anoplophora glabripennis, oviposition slit, water content, pH, microbe community, diversity
