摘要: 应用变性梯度凝胶电泳(denatured gradient gel electrophoresis,DGGE)分析了褐飞虱体内细菌的群落结构。结果表明,褐飞虱1龄~5龄若虫体内细菌的菌群结构随其生长发育而异,而羽化后的成虫与1龄若虫的菌群结构具有较高的相似性。根据DGGE聚类分析结果,9个地理种群褐飞虱体内细菌可分为3类,菲律宾单独一组,泰国与我国的海南、云南和浙江种群为一组,越南与我国的广西、湖南和江西种群为一组。取食感虫品种的TN1种群褐飞虱体内细菌的群落结构相似,与取食抗虫品种的ASD7种群和Mudgo种群之间具有较明显的差异,但取食不同抗虫水稻品种的褐飞虱还未能得到有效区分。

Abstract: The   bacterial community  structure in  different virulent populations of brown planthopper (BPH), Nilaparvata lugens (Stl), was analyzed by   denatured gradient gel electrophoresis (DGGE). The results showed that the bacterial community in BPH nymph from  the 1st to  the 5th instars varied with nymphal growth and development, and the bacterial community in  the 1st instar BPH nymph was similar to  that in adults. Nine geographic BPH populations were obviously divided into three groups  according to the cluster analysis  based on DGGE fingerprint. The first group  came  from the Philippines, the second   from Thailand and the provinces of Hainan, Yunnan and Zhejiang of China, and the third   from Vietnam and the provinces of Guangxi, Hunan, and Jiangxi of China. BPH populations  on  Mudgo (with resistant gene Bph1) and ASD7 (with resistant gene bph2) have similar bacterial community,  while differed to  that fed on susceptible rice variety, TN1.

Key words: denatured gradient gel electrophoresis (DGGE), brown planthopper (BPH), Nilaparvata lugens, bacterial community, geographic population, virulent to resistant varieties
