浙江省带土苗木传带红火蚁风险调查分析

Risk investigation and analysis of red imported fire ants with soil-grow seedlings in Zhejiang Province,China

带土苗木传带红火蚁Solenopsis invicta是导致红火蚁疫情进一步扩散蔓延的关键因素,摸清浙江省带土苗木传带红火蚁的风险,对其快速阻截与有效防控具有重要意义。2016年12月至2022年9月期间,本研究通过问询、目测踏查、诱饵诱集等监测方法,调查了浙江省11个地级市的39个区或县,包括251个苗圃地、26个花卉交易市场、576个档口的红火蚁发生情况。结果表明,龙血树Dracaena draco、玉兰Yulania denudata、山茶Camellia japonica、菜豆树Radermachera sinica、丝葵Washingtonia robusta、木犀Osmanthus fragrans、苏铁Cycas revoluta、樟Cinnamomum camphora、罗汉松Podocarpus macrophyllus、紫叶李Prunus cerasifera、加拿利海枣Phoenix canariensis、叶子花Bougainvillea spectabilis等是浙江省高风险传带红火蚁的带土植物种类。建议今后应该加大对该类带土苗木的检疫,快速发现并阻截红火蚁入侵。

The transmission of Solenopsis invicta by soil-grow seedlings is the key factor leading to the further spread of the epidemic.It is of great significance to find out the risk of S.invicta carried by soil-grow seedlings in Zhejiang Province for its rapid prevention and control.From December 2016 to September 2022,we investigated the occurrence of S.invicta in 39 districts or counties of 11 prefecture-level cities in Zhejiang Province,including 251 nursery lands,26 flower markets,576 stalls through inquiry,visual inspection and baiting.Results showed that Dracaena draco、Yulania denudata、Camellia japonica、Radermachera sinica、Washingtonia robusta、Osmanthus fragrans、Cycas revoluta、Cinnamomum camphora、Podocarpus macrophyllus、Prunus cerasifera、Phoenix canariensis、Bougainvillea spectabilis were the high-risk species carrying S.invicta.In order to quickly detect and stop the invasion of S.invicta,we suggest that the quarantine of these soil-grow seedlings should be strengthened in the future.
