The non-enveloped virus particles (virions) of DXV are 60 nm in diameter and show icosahedral symmetry with a triangulation number of T = 13. The genome is divided into two segments of a double-stranded RNA (bipartite): segment A has a size of 3360 bp , segment B of 3243 bp. The DXV infects the fruit fly Drosophila melanogaster . It is of great importance in connection with research into the innate immune system in insects.
In addition to this officially confirmed representative of the Entomobirneviridae , the National Center for Biotechnology Information (NCBI) also lists the Tetranychus urticae-associated entomobirnavirus as a proposed candidate .
