辽宁省美国白蛾防控策略分析

Analysis on the prevention and control strategy for American white moth in Liaoning Province

美国白蛾是一种危害严重的外来林业有害生物,因其具有食性杂、繁殖力强、防治难度大等特性,成为我国森林植物检疫对象之一。美国白蛾传播速度快、范围广,可随着交通沿线迅速传播,并随着调运物入侵行道树。因此,对其调查监测及防治十分重要。近年来,辽宁省的美国白蛾得到了有效控制,危害程度有所降低,但由于受美国白蛾生物学特性和气候变化以及物流活动频繁等因素的影响,美国白蛾仍有很强的发展势头。针对辽宁省美国白蛾防控策略进行了分析,提出了卓有成效的防治措施,其中主要包括加大生物防治力度、开展专业化防治、实行联防联治和强化疫情监测等建议。
