西花蓟马的抗药性及其治理策略

西花蓟马Frankliniella occidentalis（Pergande）是世界性的园艺作物上的重要害虫,几乎对每种类型的杀虫剂均产生了抗药性,包括有机磷、氨基甲酸酯、拟除虫菊酯类杀虫剂和多杀菌素等。本文对国外西花蓟马的抗药性发展现状和抗性机制进行了总结,并提出了抗性治理策略,即科学合理使用杀虫剂,结合栽培防治、物理防治、生物防治和寄主植物抗性等方式降低杀虫剂对西花蓟马的选择压,从而达到抗性治理的目的。

Insecticide resistance of western flower thrips Frankliniella occidentalis and its management strategies

The western flower thrips,Frankliniella occidentalis（Pergande）,is a serious global pest of a wide range of host plants,including open-field ornamental crops,fruit,garden,and agricultural crops.It has developed resistance to almost every kind of insecticide,including organophosphates,carbamates,pyrethroids and spinosad.This paper reviews the resistance of western flower thrips to every class of insecticide and the mechanisms underlying this resistance.An insecticide resistance management（IRM） strategy is proposed with the key objective of decreasing reliance on insecticides to control western flower thrips.This involves as using insecticides scientifically,in combination with other control methods,including as cultural,physical,genetic and biological control approaches.
