Helicoverpa zea female moths productively infected with Hz-2V have malformed reproductive tissues and are sterile. Virus replication in infected females occurs primarily in the reproductive tissues and culminates with the accumulation of virus-filled vesicles, which form plugs of virus covering the reproductive openings of these insects. The location of this large concentration of virus particles at the terminal abdominal segment of infected females suggests that it may serve as a source of virus that can be transmitted horizontally between moths during mating. In mating experiments it was found that healthy males are attracted to and attempt to mate with infected females, and that these males are able transmit Hz-2V to healthy females during subsequent matings, giving rise to virus infected progeny.
