Type Species

Campoletis sonorensis ichnovirus

(CsIV)

Distinguishing Features

Ichnoviruses have been found only in the wasp family Ichneumonidae. Ichnovirus nucleocapsids are fusiform in shape, and are enveloped by two unit membranes. Typically, virus particles each contain a single nucleocapsid (viruses from the wasp genera Glypta and Dusona are the only known exceptions) (Fig. 1).

List of Species Demarcation Criteria in the Genus

To experimentally demonstrate that a parasitic wasp carries an ichnovirus the following criteria should be met:

Virions isolated from oviduct of females of an ichneumonid wasp species,

Virions have ichnovirus morphology having a single lenticular or fusiform nucleocapsid, a double unit membrane, and size of 300 nm 60 nm,

Nucleic acid isolated from virions is DNA from multiple molecules (i.e., DNA genome is segmented),

Reference specimens of the wasp host are identified to species by a qualified ichneumonid systematic specialist and are deposited in an accessible insect collection.

Criteria that are thought to be of systematic significance:

Lepidopteran host range of virus (the non-replicative host),

DNA restriction map profiles.
