摘  要:木瓜秀粉蚧是近年来入侵我国的世界检疫性害虫,在我国南方多个省份均有发生危害,对园林植物、粮食作物具有潜在严重危害风险。为明确木瓜秀粉蚧在福州的危害情况,为园林、农业部门监测和防治提供科学依据。2021—2023年,采用目测法和搜索踏查的方法,对福州市辖区的居民住宅小区、公园绿地、交通主干道和单位庭院的木瓜秀粉蚧发生危害情况进行调查。结果显示,木瓜秀粉蚧在福州为害的植物种类涉及23科34属35种,其中6科23种植物为首次报道。从植株受害率分析,朱缨花、木槿和番木瓜等寄主植物的受害率最高,均大于80%;从寄主受害指数分析,一串红和水茄受害最为严重。木瓜秀粉蚧已经在福州市14种植物上严重为害,特别是居民住宅小区和道路主干道绿化植物上。木瓜秀粉蚧对粮食安全的潜在威胁需要引起高度警惕。The papaya mealybug,Paracoccus marginatus Williams and Granara de Willink,is a globally significant quarantine pest that has recently invaded China,causing damage in several southern provinces.This pest has the potential harm to ornamental plants and food crops seriously.In order to clarify the occurrence and damage of P.marginatus in Fuzhou,providing scientific references for its monitoring and controlling this pest by the gardening and agricultural sectors.A combination of visual method and search surveys was used to conduct on the occurrence and damage caused by P.marginatus in residential areas,parks green spaces,main traffic roads and courtyard of the unit within the jurisdiction of Fuzhou from2021 to 2023.The pests infected 35 species of plants belonging to 34 genera and 23 families,including23 species from 6 families being reported for the first time.Analysis of plant damage rates showed that the highest infestation rates,exceeding 80%,were observed in host plants such as Calliandra haematocephala,Hibiscus syriacus and Carica papaya.The host damage index indicated that Salvia splendens,Solanum torvum were the most severely damaged.P.marginatus has seriously harmed 14 species of greening plants in Fuzhou,particularly on the green plants in residential areas and main traffic roads.The potential threat of P.marginatus to food security requires heightened vigilance.
