苹果全爪螨抗药性研究进展

苹果全爪螨是重要的蔷薇科果树害虫之一, 具有体型小、繁殖快、世代周期短等生物学特点。该螨以若螨和成螨取食苹果叶片和嫩芽, 影响果树生长发育, 造成果实品质和产量下降, 自20世纪60年代开始其在我国果园的发生逐年加重。国内外对苹果全爪螨的防治主要采用化学杀螨剂, 由于化学杀螨剂长期不规范的使用, 致使该螨对多种类型的化学杀螨剂产生了抗药性。本文总结了苹果全爪螨的发生、为害、抗药性现状及其抗性机理, 同时结合国内外苹果全爪螨抗药性和防治相关研究, 提出该螨抗药性治理策略, 以期为其防治提供参考。

Advances in acaricide resistance of the European red mite, Panonychus ulmi (Koch)

The European red mite, Panonychus ulmi (Koch) (Acari: Tetranychidae), is one of the most important pests of Rosaceae fruit trees. It has small body size, with rapid reproduction and short generation time. The nymphs and adults of mites feed on the leaves and tender buds of apple, affecting the growth and development of fruit trees, resulting in the decrease of fruit quality and yield. The damages by P. ulmi more and more seriously since the 1960s. Spraying chemical acaricide is the main method for control of P. ulmi. Due to the long-term irregular use of chemical acaricides, the mite has developed resistance to various types of chemical insecticides. In this reviews, the occurrence, damage, resistance status and resistance mechanism of P. ulmi were summarized. The acaricide-resistance management and integrated control of P. ulmi was proposed.
