In order to clarify the composition of intestinal bacteria of adult Sogatella furcifera(Horváth) and the difference between male and female adults, this study isolated and cultured the composition of intestinal bacteria of adult Sogatella furcifera(Horváth) in paddy field of Yuanjiang County, Yunnan Province by using traditional culture method, and identified the species of bacteria by using morphological and 16S rDNA sequence alignment method. The results showed that 20 species, 12 genera, 8 families, 3 phyla of bacteria were isolated and identified from the intestinal tract of the planthopper. The dominant bacteria Phylum are Firmicides (50%). The dominant bacteria genera in the intestinal tract of female adults are Staphylococcus (25%) and the dominant bacteria species are Staphylococcus squirrel (25%). The dominant bacteria genera in the intestinal tract of male adults are Bacillus (22%) and Microbacter (22%), and the dominant bacteria species are Microbacterium laevaniforman (22%). Among them, 12 species belonging to 8 genera, 8 families and 3 phyla were isolated from the intestinal tract of female adults, including 3 species of Bacillus, 1 species of Staphylococus, 1 species of Acinetobacteris, 1 species of Pantoea, 2 species of Pseudomonas, 1 species of Ochrobactrumis, 2 species of Microbacterium. In the intestinal tract of male adults, 12 species, 10 genera, 8 families and 3 phyla were isolated, including 1 species of Lysinibacillusis, 1 species of Fictibacilluis, 3 species of Bacillusare, 1 species of Staphylococus, 1 species of Exiguobacterium, 1 species of Enterobacter, 1 species of Acinetobacter, 1 species of Pseudomonas, 1 species of Stenotrophomonas, 1 species of Microbacterium. There are four common species of bacteria in the gut of male and female adults of Sogatella furcifera(Horváth), namely Staphylococcus squirrel, Micrococcus acetylus, Micrococcus dextrogenes and Acinetobacter soli. This study will provide a theoretical basis for the further study of the intestinal bacterial function of Sogatella furcifera(Horváth), and the difference of intestinal bacterial composition between male and female and its mechanism. |
