摘要 為明确几种药剂对草地贪夜蛾Spodoptera frugiperda幼虫的田间防治效果,合理使用化学农药对草地贪夜蛾进行科学防治提供理论依据。对氯虫苯甲酰胺、氟铃·茚虫威、甲维·高氯氟、乙基多杀菌素、乙多·甲氧虫、虱螨脲、阿维·氯苯酰、氯虫·高氯氟、甲氨基阿维菌素苯甲酸盐等9种药剂进行了玉米和马铃薯田间防效试验。结果表明,9种药剂对两种作物上草地贪夜蛾幼虫均有一定毒杀作用,乙多·甲氧虫、乙基多杀菌素和氯虫苯甲酰胺可作为应急防控的首选药剂,氯虫·高氯氟、阿维·氯苯酰和甲维·高氯氟可作为应急防控药剂轮换使用。

Abstract
In order to clarify the field control effect of several pesticides on Spodoptera frugiperda, the rational use of chemical pesticides on the scientific control of S.frugiperda provides a theoretical basis. In this paper, the field control effects of nine insecticides on corn and potato were studied, including chlorantraniliprole, hexaflumuron·indoxacarb, emamectin benzoate·lambda-cyhalothrin, spinetoram, spinetoram·methoxyfenozide, lufenuron, abamectin·chlorantraniliprole, chlorantraniliprole·lambda-cyhalothrin and abamectin-aminomethyl. The results showed that the nine insecticides had certain toxic effects on the larvae of S.frugiperda on the two crops, of which spinetoram·methoxyfenozide, spinetoram and chlorantraniliprole could be used as the preferred agents for emergency control, while chlorantraniliprole·lambda-cyhalothrin, abamectin·chlorantraniliprole and emamectin benzoate·lambda-cyhalothrin could be used as substitutes for pesticide alternation.

草地贪夜蛾Spodoptera frugiperda(J.E.Smith),起源于美洲热带和亚热带地区,是联合国粮农组织(FAO)全球预警的重大害虫[1],寄主范围广,可取食76科353种植物[2-3],尤其对玉米、水稻、高粱、花生、棉花、大豆和甘蔗等粮食作物为害较重[4-5]。目前已在美洲、非洲、亚洲的106个国家发生为害。草地贪夜蛾
自2019年1月首次入侵我国后,迅速蔓延,截至10月8日,已侵入西南、华南、江南、长江中下游、黄淮、西北、华北地区的26个省(区、市)1 538个县(区、市),发生面积106.5万hm2[6]。7月16日,山东省滕州市春玉米田首次发现草地贪夜蛾幼虫为害,之后迅速扩展蔓延至全省13个地市44个县(市、区)以及5个经济开发区。该虫取食量大、繁殖力强、食性范围广,严重威胁粮食生产。本文结合该虫在山东的为害特点及农业生产实际,对9个农药制剂进行试验,明确各药剂的适用剂量和防效,为田间防治提供依据。……
