Pathology and replication of the sexually transmitted insect virus HzNV-2
John Burand (University of Massachusetts Amherst)
Although most viruses are known for the diseases they cause nearly all viruses are able to persist in their host in a latent or occult state.
The insect virus HzNV-2 is a sexually transmitted virus that has evolved to manipulate the reproductive physiology of its host to facilitate replication and transmission.
In the process the host loses reproductive ability and is sterile.
Not all virus infected insects are sterile however since the virus has evolved a mechanism by which it can be maintained in the insect population being transmitted transovarially to the next generation of insects by fertile, asymptomatic female moths.
