Pine wilt disease ( PWD ) has a tremendous impact on worldwide forestlands, both from the environmental and economical viewpoints. M onochamus sp., a xylophagous insect from the C erambycidae family, plays an important role in dissemination of the pinewood nematode, B ursaphelenchus xylophilus , the primary pathogenic agent of PWD . This study investigates, for the first time, the bacterial communities of M onochamus galloprovincialis collected from Portuguese Pinus pinaster trees and B . xylophilus free, using a metagenomics approach. Overall, our results show that natural bacterial communities of M . galloprovincialis are mainly composed by γ‐proteobacteria, F irmicutes and B acteroidetes , which may be a reflection of insects' feeding diet and habitat characteristics. We also report different bacterial communities' composition in the thorax and abdomen of M . galloprovincialis , with high abundance of S erratia sp. in both. Our results encourage further studies in the possible relationship between bacteria from the insect vector and B . xylophilus .
