Anoplophora glabripennis (Asian longhorned beetle) is a wood-boring pest that can inhabit wide range of healthy deciduous host trees in native and invaded areas. The gut microbiota plays important roles the acquisition nutrients for growth development A. larvae. Herein, we investigated larval structure studied lignocellulose activity microbial communities following feeding on different trees. was divided into foregut, midgut, hindgut, which midgut longest, forming single loop under itself. Microbial community composition extracts were correlated with tree species. larvae fed preferred (Populus gansuensis) had higher diversity than reared either secondary (Salix babylonica) or resistant alba var. pyramidalis). Wolbachia most dominant bacteria S. babylonica P. pyramidalis, while Enterococcus Gibbsiella gansuensis, followed by Wolbachia. lignocellulose-degrading fungus Fusarium solani Functional predictions suggested they all play role degrading lignocellulose, detoxification, fixing nitrogen, likely contribute to ability these thrive broad
