摘要
棉铃虫是农作物上的重要害虫,在棉花、蔬菜、玉米和向日葵等作物上均有发生。棉铃虫适生区域、寄主较为广泛,发生代数多,繁殖能力、迁飞性和抗药性都较强。棉铃虫的发生规律受环境、气候、寄主作物等因素影响,不及时治理可导致作物减产,对农业生产造成重大损失。针对2023年12月31日前中国农药信息网中防治棉铃虫药剂的登记情况,分别从数量、有效成分、剂型、机理、药剂密度及生产企业等数据进行统计与分析,针对存在农药重复登记、缺乏创新、研发思路单一、抗性严重、有效成分与剂型杂乱及混剂成分多且复杂等问题,结合当前形势提出发展建议,以期为棉铃虫防治提供参考。
Helicoverpa armigera is an important crop pest,which occurs on cotton,vegetables,corn and sunflowers.Helicoverpa armigera has a wide range of suitable areas and hosts,a large number of generations,strong reproductive ability,migration and resistance to insecticides.Occurrence pattern of Helicoverpa armigera is affected by environment,climate,host crops and other factors,and failing to control it in time can lead to crop yield reduction,and causing great losses for agricultural production.Registration status of insecticides for controlling Helicoverpa armigera in China Pesticide Information Network before December 31,2023,was analyzed from quantity,active ingredient,dosage form,pesticide mechanism,pesticide density,and manufacturers,respectively.Problems of repeated registration of pesticides,lack of innovation,single research and development ideas,serious resistance,messy pesticide ingredients and dosage forms,and complex mixed ingredients were put forward,and development suggestions were put forward based on current situation,to provide reference for control of Helicoverpa armigera.
