Abstract

Abstract : The small brown planthopper (SBPH) is an important virus vector, transmitting Rice stripe virus (RSV), and Rice black‐streaked dwarf virus (RBSDV). Insect symbionts play an essential role in the insect fitness, however, it is still unclear about their contributions to viral transmission by SBPH. Here, we investigated endosymbiont communities in non‐viruliferous, RSV‐infected, and RBSDV‐infected SBPH populations using Illumina 16S rRNA gene MiSeq sequencing. In total, 281, 803 effective sequences of the 16S rRNA gene were generated from different samples. Sequence analysis revealed the percentages of these bacterial groups in different SBPH populations on several taxonomic levels ranging from phyla to genera. The extremely consistent bacterial diversity and abundance indicated that RSV or RBSDV infection did not affect the composition and abundance of symbionts in SBPH. It was notable that Wolbachia was dominant in all populations. The symbiosis between Wolbachia and SBPH might be potentially studied and utilized to control pest SBPH in the future.
