Abstract：
[Aim] Gastrophysa atrocyanea is an insect that feeds on weeds of the family Polygonaceae. [Methods] High- throughput
sequencing analysis was used to investigate the type, abundance, dominance and
diversity of, and functional changes in, the gut microbiota in G. atrocyanea that fed on either Rumex acetosa or Rheum tanguticum. [Results] A total of
154 gut microbiota species were identified, of which 548 were unique to G.
atrocyanea that fed on R. acetosa and 554 to those that fed on R. tanguticum. The Proteobacteria was
the dominant gut microbiota in both treatment groups. Species diversity was
highest in G. atrocyanea that had fed on R. tanguticum. The species composition predicted from the results
of a metabolic function analysis indicate that, except for Serratia, the
dominant group in the R. acetosa treatment group was Pantobacterium, and
the dominant group in the R. tanguticum treatment group was Enterobacterium. [Conclusion] This study preliminarily
clarified the diversity characteristics of gut microbiota of G. atrocyanea that feed on R. acetosa and R. tanguticum, providing a
theoretical basis for its host range and population outbreak prediction.
