Abstract: In October 2020, ICTV updated the Master Species List which created the new class of Naldaviricetes and the new order of Lefavirales. Lefavirales consists of three families including the Baculoviridae. Baculoviridae is divided into four genera:Alphabaculovirus, Betabaculovirus, Deltabacuulovirus, and Gammabaculovirus. Total 85 major baculovirus species are included in the list. According to the ICTV website, the baculovirus species name consists of the host insect species name and virus characteristic words (nucleopolyhedrovirus or granulovirus), the initial letter of the host genus is uppercase, the other letters are lowercase. The virus species name (when used for system classification) is written in italics, but in other cases, the virus name including the name of a host species should never be italicized. The abbreviation of baculovirus name consists of the first two letters of the host genus and those of the species name followed by the abbreviation of nucleopolyhedrovirus (NPV) or granulovirus (GV), while the 16 traditional baculovirus abbreviations still use the acronyms of host genus and species name followed by NPV or GV.
