武汉市美国白蛾监测与防控措施研究

MonitoringandControlMeasuresofHyphantriacuneainWuhan

摘要:

美国白蛾是国际检疫性有害生物,武汉市毗邻 4个美国白蛾疫区,为了加强监测与防控研究工作,从 2019年开 始将全市 15个行政区划分为中心城区和远城区两个监测区域,共布设性诱捕器监测点位 490个,安装智能监测灯 50台。 研究结果表明,2021~2022年利用性信息素诱捕器在 5个行政区监测诱捕到 16只美国白蛾成虫,人工调查未见网幕、幼虫 及越冬蛹 。分析监测诱捕到成虫的时间、地点及后续跟踪调查结果,推断为物流带入 。针对美国白蛾疫情威胁的严峻防控 形势,切实做好监测预警,及时发现疫情,迅速封锁扑灭,是阻止疫情入侵蔓延的主要措施。
