新烟碱类杀虫剂呋虫胺的研究进展

新烟碱类农药自20世纪80年代上市以来便受到广泛应用。呋虫胺作为典型的第三代新烟碱类杀虫剂,因其高效、广谱等优点在全球二十多个国家登记使用。近年来,随着呋虫胺的大量使用,其对非靶标生物的潜在危害,以及在农业生产中大量投入导致的环境风险引起了人们的重点关注。因此,阐明呋虫胺的生物活性和生态毒理,揭示其环境行为归趋,这对于呋虫胺的生态风险评价与科学合理使用具有重要意义。笔者旨在综述呋虫胺对靶标害虫的生物活性、对非靶标生物的生态毒理,及其在生态环境中的耗散动力学规律,并对其应用前景进行展望,以期为呋虫胺的合理使用和科学管理提供有效参考。

Research Progress of Neonicotinoid Insecticide Dinotefuran

Neonicotinoid pesticides have been given extensively concern since they were launched in the 1980s.As a typical third-generation neonicotinoid insecticide,dinotefuran has been widely used in more than twenty countries around the world because of its high efficiency and broad spectrum.In recent years,dinotefuran shows potential hazardous to non-target organisms and results in the ecological environment pollution by widespread application in agricultural production,which have brought to people's attention.Therefore,understanding the biological activity and ecotoxicity of dinotefuran,and demonstrating the environmental fate of dinotefuran is of great significance to the ecological risk assessment and scientific application of dinotefuran.The current study reviews dinotefuran with respect to the biological activity to target pests,the ecotoxicity to non-target organisms,the dissipation dynamics in the ecological environment,and finally puts forward prospects for its application.It can provide reference for the reasonable application and scientific management of dinotefuran in the future.
