葡萄花翅小卷蛾抗药性研究进展

Insecticide resistance review of a quarantine pest,European grapevine moth Lobesia botrana

葡萄花翅小卷蛾是葡萄上的重要害虫,具有多食性、多化性等生物学特点,抗逆能力极强。该虫起源于欧洲,现已入侵全球多个国家。葡萄花翅小卷蛾主要以幼虫取食葡萄花序、幼果和成熟果实,给葡萄生产造成重大损失;其危害有利于真菌的侵入,导致灰霉病、白粉病等病害大量发生,从而造成葡萄腐烂。由于该虫入侵风险极高,已被我国列为重要的进境检疫性有害生物。国外对葡萄花翅小卷蛾的防治主要采用化学杀虫剂,由于长期大量且不合理地使用化学杀虫剂,葡萄花翅小卷蛾已对多种不同类型的杀虫剂产生了抗药性。本研究总结了葡萄花翅小卷蛾的抗性测定方法、抗性现状及其抗性机理,同时结合国外葡萄花翅小卷蛾抗性和防治相关研究,提出该虫抗性治理策略,并对我国预防该虫的入侵提出建议。

The European grapevine moth Lobesia botrana is an important economic pest on grapes.It is a polyphagous and multivoltine species with strong adaption to environmental stresses.This pest originated in Europe and has successfully colonized many countries around the world.Larvae of the moth mainly feed on grape inflorescences,green fruits and mature fruits,causing great losses in grape production.The pest can cause damage that can increase fungal infection,leading to gray mold and powdery mildew.Due to the extremely high risk of L.botrana invasion,it has been listed as an important entry quarantine pest in China.Chemical control is the major approach of controlling European grapevine moth in different countries.With the long-term and unreasonable use of chemical pesticides,this pest has developed resistance to different types of pesticides.In this paper,we summarize the insecticide resistance measurement methods,as well as the resistance status and mechanisms of the pest to different insecticides.We propose some potential management strategies to reduce resistance development.
