麦蚜对拟除虫菊酯类杀虫剂抗性研究进展

Research advances in pyrethroid insecticide resistance in wheat aphids

麦蚜是为害小麦的一类重要害虫,广泛分布于我国各小麦种植区。2016年-2018年我国麦蚜总体偏重发生,严重影响小麦产量和品质,造成巨大的经济损失。拟除虫菊酯类杀虫剂是防治麦蚜的主要杀虫剂类型之一,但由于化学农药的长期使用,麦蚜对拟除虫菊酯类杀虫剂产生了不同程度的抗性。本文综述了拟除虫菊酯类杀虫剂作用机制、麦蚜对拟除虫菊酯类杀虫剂的抗性现状以及近年来拟除虫菊酯类杀虫剂抗性机制研究的主要进展。

Wheat aphids are a group of important pests that infect wheat cereal and are widely distributed in China.The overall occurrence of wheat aphids in China in 2016-2018 has seriously affected wheat yield and quality,causing huge economic losses.Pyrethroid insecticides are among the main types of insecticides for controlling the wheat aphid.However,due to the long-term use of chemical insecticides,wheat aphids have developed varying degrees of resistance to pyrethroid insecticides.This article reviewed the mechanisms of action of pyrethroid insecticides,the current status of resistance of wheat aphids to pyrethroid insecticides,and the main advances in the research of pyrethroid insecticide resistance mechanisms in recent years.
