Popis: Apriona germari is one of the most serious wood-boring pests that cause damage to economic and landscaping trees and has adapted to a wide range of plants as diet. Gut bacteria play an important role in biology and ecology of herbivores, especially in growth and adaptation. To investigate how plant hosts shape A. germari gut microbiota, A. germari larvae were collected from Populus tomentosa and Malus pumilal, and gut microbiomes were sequenced based on 16S rDNA high-throughput sequencing technology. A total of 853,424 high-quality reads were obtained and clustered into 196 operational taxonomic units under a 97% similarity cutoff, which were annotated into 8 phyla, 10 classes, 21 orders, 34 families, 59 genera, and 39 species. Gibbsiella was the most dominant genus of intestinal bacteria, followed by Enterobacter and Acinetobacter. No significant difference was observed in larvae gut bacterial richness and diversity of A. germari collected from two hosts, though alpha diversity showed that the richness of gut bacteria in A. germari larvae collected on P. tomentosa was slightly higher than that in A. germari on M. pumilal, and beta diversity showed little difference between two host plants. The functional abundance analysis of the detected bacteria revealed fermentation, chemoheterotrophy, symbionts, and nitrate relative functions that highly possibly support wood-boring beetles to feed on woody tissues. Our study provided a theoretical basis for investigating the function of intestinal symbiosis bacteria of A. germari.
