With the recent introduction of the non-native spotted lanternfly () to the USA, research and concern regarding this insect is increasing. Though is able to feed on many different plant species, its preference for the invasive tree-of-heaven () is apparent, especially during its later life stage. Therefore, management focused on control to help limit establishment and population growth has become popular. Unfortunately, the control of is difficult. , a naturally occurring vascular-wilt pathogen, has recently received attention as a potential biological control agent. Therefore, we studied if fourth instars or adults could vector from infected material to healthy seedlings in a laboratory setting. We were unable to re-isolate from the 45 seedlings or from the 225 utilized in this experiment. We therefore, found no support that could effectively vector this pathogen between in laboratory conditions. Since 's ability to vector has implications for the dissemination of both this beneficial biological control and other similar unwanted plant pathogens, future research is needed to confirm these findings in a field setting.
随着外来物种斑衣蜡蝉最近被引入美国，关于这种昆虫的研究和关注度不断增加。虽然斑衣蜡蝉能够取食多种不同的植物物种，但它对入侵树种臭椿的偏好很明显，尤其是在其后期生命阶段。因此，以控制斑衣蜡蝉来帮助限制其定殖和种群增长为重点的管理措施变得流行起来。不幸的是，控制斑衣蜡蝉很困难。悬铃木溃疡病菌，一种天然存在的维管束萎蔫病原体，最近作为一种潜在的生物防治剂受到关注。因此，我们研究了四龄若虫或成虫是否能在实验室环境中将悬铃木溃疡病菌从受感染的臭椿材料传播到健康的臭椿幼苗上。我们无法从本实验中使用的45株臭椿幼苗或225株臭椿中重新分离出悬铃木溃疡病菌。因此，我们没有发现证据支持斑衣蜡蝉能在实验室条件下在臭椿之间有效传播这种病原体。由于斑衣蜡蝉传播悬铃木溃疡病菌的能力对这种有益生物防治剂和其他类似的有害植物病原体的传播都有影响，未来需要在田间环境中进行研究以证实这些发现。
