摘要
飞虱Lycorma delicatula (White)(斑点灯笼蝇;SLF)是从亚洲引入北美的。2014年,它首次在宾夕法尼亚州东南部被发现,十年后的今天,它的数量增加了,并蔓延到美国东部的18个州。为了研究自然发生的真菌病原体感染SLF,在宾夕法尼亚州东部地区,于2020年和2021年每1至2周采样一次,在L. delicatula成虫阶段,检测真菌Batkoa major (Thaxt)感染的流行情况。球孢白僵菌(Bals.-Criv.)Vuill。(肉座菌目:Cordycipitaceae)。采集成人活体SLF饲养,诊断死亡原因。2020年,在2018年发生这两种多面手病原体共发生兽疫的地点,9月30日至10月21日记录了一起由大b型兽疫引起的兽疫。在另外一个2020年和两个2021年的站点检测到两种病原体的低水平感染。总体而言,大白僵菌感染与SLF密度呈负相关,与球孢白僵菌密度无相关性。两种真菌在个体SLF中的共同感染从未被记录在案,并且在采样人群中,主要白僵菌和球孢白僵菌感染的患病率之间存在反比关系。在对用于饲养的SLF进行采样的同时,也对成年尸体进行采样。主要白僵菌的感染率与饲养个体呈正相关,但尸体感染率高于饲养个体。对于球孢白僵菌,没有发生这样的模式。
Epizootiology of infections by Batkoa major (Entomophthorales: Batkoaceae) and Beauveria bassiana (Hypocreales: Cordycipitaceae) in spotted lanternfly (Hemiptera: Fulgoridae) populations.
The planthopper Lycorma delicatula (White) (spotted lanternfly; SLF) was introduced to North America from Asia. It was first found in southeastern Pennsylvania in 2014 and now, a decade later, has increased in abundance and spread into 18 eastern US states. To study naturally occurring fungal pathogens infecting SLF, eastern Pennsylvania sites were sampled every 1 to 2 wk in 2020 and 2021 during the adult life stage of L. delicatula to detect prevalence of infections by the fungi Batkoa major (Thaxt.) Humber (Entomophthorales: Batkoaceae) and Beauveria bassiana (Bals.-Criv.) Vuill. (Hypocreales: Cordycipitaceae). To sample, living adult SLF were collected and reared and cause of death was diagnosed. In 2020, at the site hosting a co-epizootic of these 2 generalist pathogens in 2018, an epizootic caused by B. major was documented from 30 September to 21 October. Low levels of infection by both pathogens were detected at an additional 2020 site and both 2021 sites. Overall, there was a negative association of B. major infection with SLF density and no association with density for B. bassiana. Co-infections in individual SLF by both fungi were never documented, and there was an inverse relationship between prevalence of B. major and B. bassiana infections in the sampled populations. At the time that SLF for rearing were sampled, adult cadavers were also sampled. For B. major, infection rates of sampled cadavers and reared individuals were positively correlated, but higher infection rates were observed in cadavers than among reared SLF. For B. bassiana, no such pattern occurred.
