Helicoverpa zea nudivirus 2

Sexually transmitted virus of corn earworm moths

Helicoverpa zea nudivirus 2 is an enveloped, rod-shaped, nonoccluded, double stranded DNA (dsDNA) sexually transmitted virus whose natural host is the corn earworm moth. At about 440 by 90 nm, it is the causative agent of the only sexually transmitted viral disease of any insect. It was originally identified in a colony of corn earworm moths established and maintained in Stoneville, Mississippi, U.S. and was found to be responsible for the sterility of those infected.
