## TL;DR

This paper presents the full genome of a highly pathogenic Bombyx mori nucleopolyhedrovirus strain from France and shows it is related to a Brazilian strain.

## Contribution

The study provides the first complete genome sequence of a European BmNPV strain and its phylogenetic relationship to a Brazilian isolate.

## Key findings

- A highly pathogenic BmNPV strain was isolated from the French Cevennes region.
- Phylogenetic analysis shows the strain is closely related to a Brazilian BmNPV strain.

## Abstract

The Bombyx mori nucleopolyhedrovirus (BmNPV) is a critical pathogen in sericulture; yet, it also holds great promise for the bioproduction of recombinant proteins. Here, we report the characterization of a highly pathogenic strain from the French Cevennes region. Phylogenetic analyses reveal that this strain is related to a Brazilian BmNPV strain.
