Abstract Background Hz-2V infection of female Helicoverpa zea moths is manifested as insects that are either sterile agonadal individuals with malformed reproductive tissues or fertile asymptomatic carriers which are capable of transmitting virus on to their progeny. Virus infected progeny arising from eggs laid by asymptomatic carrier females may themselves be either sterile agonadals or asymptomatic carriers. Results By injecting virus into female moths a correlation was established between virus doses administered to the females and the levels of resulting asymptomatic and sterile progeny. Conclusions The results of these experiments indicate that high virus doses produced a higher level of agonadal progeny and lower doses produced higher levels of asymptomatic carriers. Background The insect virus Hz-2V originally named gonad-specific virus GSV 1 was first identified in moths from a colony of corn earworms Helicoverpa zea originating at the USDA-ARS in Stoneville MS 1 2 .
