bracovirus

plural bracoviruses

1. Any member of the genus Bracovirus, of viruses that are symbiotic with specific braconids.

   The genetic analyses of the bracovirus Cm V support the hypothesis of transmission of polydnaviruses through the wasps' germline, but the mechanism utilized by bracoviruses presently is unclear.

   This paper focuses on the evolution of the bracoviruses. Currently, this group is more promising than the ichnoviruses for evolutionary study because the phylogenetic relationships among the braconid carriers are better understood.[…]Recently, braconids carrying bracoviruses were determined to comprise a monophyletic lineage within the Braconidae (Fig. 1 in Whitfield 1997).

   Based on preliminary fossil data, the appearance of polydnaviruses within microgastrid genera may predate Eocene and Oligocene deposits and has led to the suggestion that the bracoviruses are derived from a single evolutionary lineage that diverged from related groups approximately 60 million years before the present (Whitfield, 1997).
