摘　　要：Rice planthoppers are notorious plant sap-feeding pests which cause serious damage.While several microbes in rice planthoppers have been broadly characterized,the abundance and diversity of bacteria and fungi in field planthoppers are largely unknown.This study investigated the bacterial and fungal community compositions of Chinese wild rice planthoppers Laodelphax striatellus and Sogatella furcifera using parallel 16S rRNA gene amplicon and internal transcribed space region sequencing.The bacteria varied sig-nificantly between the species and were partitioned significantly by sex,tissues and host environments in each species.The majority of bacteria were affiliated with the genera Wol-bachia,Cardinium,Rickettsia and Pantoea.The abundance of Wolbachia was negatively correlated with that of Cardinium in both planthopper species.Compared with bacteria,the abundance and diversity of fiungi did not differ between sexes but both were enriched in the gut.The bacterial community as a whole showed no significant correlation with the fungal community.The majority of fungi were related to Sarocldium,Alternaria,Malasseria,Aspergillus and Curvularia.A phylogenetic analysis revealed that these fungi were closely related to botanic symbionts or pathogens.Our results provide novel insights into the bacteria and fungi of rice planthoppers.
