Due to similarities in pathology and morphology to members of the family Baculoviridae, they have been previously classified as the so-called “non-occluded” baculoviruses. However, presently they are taxonomically orphaned and are not assigned to any virus family because of the lack of genetic relatedness to Baculoviridae,. Here, we report on recent progress in the genomic analysis of Heliothis zea nudivirus 1 (HzNV-1), Oryctes rhinoceros nudivirus (OrNV), Gryllus bimaculatus nudivirus (GbNV) and Heliotis zea nudivirus 2 (HzNV-2). Gene content comparison and phylogenetic analyses indicated that the viruses share 15 core genes with baculoviruses and form a monophyletic sister group to them. Consequences of the genetic relationship are discussed for the classification of nudiviruses.展开更多

The most common viruses of mosquitoes are the baculoviruses (DBVs) (Baculoviridae: Deltabaculovirus), cytoplasmic polyhedrosis viruses (CPVs) (Reoviridae: Cypovirus) and the iridoviruses (MIVs) (Iridoviridae: Chloriridovirus). Baculoviruses and iridoviruses are DNA viruses while cypoviruses are the main RNA viruses in mosquitoes. This review presents an overview of the current status and recent advancements in understanding the biology and molecular features of mosquito pathogenic viruses.展开更多
