Abstract This study measured the changes of microorganisms in the midgut and habitat niche of Rhynchophorus ferrugineus Olivier, an invasive quarantine pest, by Illumina sequencing. The bacterial diversity in the R. ferrugineus larvae midgut and their habitat niche was compared to the uninfected P. sylvestris. The Proteobacteria and Firmicutes occupied a dominant position in the R. ferrugineus midgut and infected P. sylvestris, while in the uninfected P. sylvestris the predominant bacterial phylum was the Cyanobacteria. Enterobacter, Dysgonomonas, and Entomoplasma were the dominant bacterial genera in R. ferrugineus midgut and also within the infected trees and uninfected trees with low relative abundance. These bacteria could be exploited as the biopesticide vector to control R. ferrugineus population. Besides, Sphingobacterium, Shinella, and Rhodobacter genera had the same distribution pattern in the infected and uninfected P. sylvestris, and these bacteria were not found in the midgut of R. ferrugineus. Interestingly, Paludibacter and Parabacteroides were only distributed in the wood fiber of the infected P. sylvestris, which could be used as potential microbial markers to detect if the palm plants are damaged by the R. ferrugineus. The results of this study will be beneficial to the development of control strategies for R. ferrugineus.

Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae) was originated in South Asia and Melanesia, it threatens the production and the utilization of the palm plants all over the world. Since 1997, R. ferrugineus has invaded the coastal areas of China, harming palm plants, and causing tremendous economic loss [1–3]. The R. ferrugineus larvae develop wit
