摘要 为弄清褐飞虱体内细菌型共生菌的分布状况,采用荧光原位杂交(FISH)技术,用Cy5标记真细菌16Sribosomal DNA(rDNA)的通用探针eub338和non338对细菌型共生菌在褐飞虱体内的分布进行了检测。结果表明:在褐飞虱虫体腹部、产卵管附近以及中场组织附近均检测到Cy5荧光信号和微弱的自发荧光信号,而反义探针non338在这些部位均未检测到Cy5的荧光信号,只检测到自发荧光信号。 The distribution of bacterial symbionts in brown planthopper was detected by the universal oligo-nucleotide probes eub338 and non338 of Cy5-labeled bacterial 16S rRNA and fluorescence in situ hybridization (FISH).The results showed that Cy5 fluorescence and weak autofluorescence signals were detected in the abdomen,near ovipositor and around midgut of brown planthopper by eub338 but the autofluorescence signal was only detected by antisense probe non338 in the abdomen,around ovipositor and midgut of brown planthopper.
