The Asian citrus psyllid (ACP) is the vector of ' Liberibacter asiaticus' (CLas), the causal agent of citrus greening or Huanglongbing (HLB), one of the most devastating citrus diseases worldwide. The citrus industry in Georgia (U.S.A.) is in the process of a rapid expansion, and based on experiences with HLB in Florida, there is great concern about the potential impacts of HLB on this emerging industry. Prior to 2023, ACP had been identified in residential citrus trees in isolated Georgia counties, but little to no testing of psyllids for CLas had occurred. However, in 2023, one individual psyllid collected from Chatham County was confirmed positive for CLas by PCR and sequencing. Furthermore, during 2023, ACP adults and nymphs were identified for the first time in a Georgia commercial citrus grove. The finding of ACP in a commercial planting represents a significant risk for CLas dissemination and thereby has the potential to stall the rapid expansion of Georgia's citrus industry. In the coming years, surveillance and testing of ACP from commercial groves will be essential for the early detection and management of HLB and its vector to reduce HLB spread within Georgia's commercial groves.
亚洲柑橘木虱是柑橘黄龙病菌（CLas）的传播媒介，柑橘黄龙病菌是柑橘黄龙病（HLB）的致病因子，柑橘黄龙病是全球最具毁灭性的柑橘病害之一。美国佐治亚州的柑橘产业正在迅速扩张，基于佛罗里达州柑橘黄龙病的经验，人们非常担心柑橘黄龙病对这个新兴产业的潜在影响。在2023年之前，在佐治亚州一些孤立的县的住宅柑橘树上发现了亚洲柑橘木虱，但几乎没有对木虱进行柑橘黄龙病菌检测。然而，2023年，从查塔姆县采集的一只木虱经PCR和测序被确认为柑橘黄龙病菌阳性。此外，2023年期间，在佐治亚州的一个商业柑橘园中首次发现了亚洲柑橘木虱成虫和若虫。在商业种植园中发现亚洲柑橘木虱对柑橘黄龙病菌的传播构成了重大风险，从而有可能阻碍佐治亚州柑橘产业的快速扩张。在未来几年，对商业果园中的亚洲柑橘木虱进行监测和检测对于柑橘黄龙病及其传播媒介的早期发现和管理至关重要，以减少柑橘黄龙病在佐治亚州商业果园中的传播。
