The peritrophic matrix (PM) acts as a physical barrier that influences the vector competence of mosquitoes. We have previously shown that gut microbiota promotes PM formation in Anopheles stephensi, although the underlying mechanisms remain unclear. In this study, we identify that the cell wall components of gut commensal bacteria contribute to PM formation.

The medicinal beetle Blaps rynchopetera is recognized for its antibacterial, anti-inflammatory, and immune-regulating properties. This study utilized metaviromics technology to systematically characterize the viral community within the gut of B. rynchopetera through high-throughput sequencing of gut contents, with a specific focus on the composition of its bacteriophage community.

We studied the viromes of three dominant mosquito species in Wenzhou, a coastal city in Zhejiang Province, using metavirome sequencing, with 18 viral families identified. Viral sequences were verified by RT-PCR. The JEV E gene was most closely related to the 1988 Korean strain.

Mosquito larvae of the genus Anopheles develop entirely in water, frequently visiting the surface for air. The aquatic environment plays a key role in shaping their microbiota, but the connection between environmental characteristics of breeding sites and larval microbiota remains underexplored. This study focuses on Anopheles arabiensis, which inhabits the surface microlayer (SML) of breeding sites, a zone with high particle density.
