Abstract

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.

摘要

被Hz - 2V有效感染的棉铃虫雌蛾生殖组织畸形且不育。病毒在受感染雌蛾体内的复制主要发生在生殖组织中，最终会积累充满病毒的囊泡，这些囊泡形成覆盖这些昆虫生殖孔的病毒栓。在受感染雌蛾腹部末端大量聚集的病毒颗粒的位置表明，它可能是病毒的一个来源，在交配过程中可在蛾类之间水平传播。在交配实验中发现，健康的雄蛾会被感染的雌蛾吸引并试图与其交配，而且这些雄蛾在随后的交配过程中能够将Hz - 2V传播给健康的雌蛾，从而产生受病毒感染的后代。
