Larvae of E. grisescens were fed the tea leaves with antibiotics for continuous 3 generations. Variation of endosymbiont community was studied using 16 S rDNA Illumina MiSeq technique. Besides, the Wolbachia of E. grisescens were detected basing on wsp gene. The results show that abundance and diversity of endosymbiont community in E. grisescens were increased and reduced, respectively under antibiotic treatments. The tetracycline and rifampicin could effectively remove Wolbachia from E. grisescens. Further, the population of E. grisescens without Wolbachia was established, which laid the foundation for the study on function of Wolbachia.
