苹果绵蚜的抗性寄主选育及无公害防治

Breeding of Resistant Hosts and Non-pollution Control of Eriosoma lanigerum Hausmann

苹果绵蚜是一种重要的检疫性害虫,原产于美国东北部,随着各国经济交流以及苹果苗木的进出口,现已分布到世界各地。苹果绵蚜一年可发生多代,严重影响苗木的生长以及苹果的质量,对苹果产业造成一定的损失。由于其体表覆盖一层蜡质绵絮,给防治带来一定的困难,因此各苹果产区都视苹果绵蚜为重点防治对象。本文重点介绍苹果绵蚜的无公害防治方法,并针对寄主抗性部分进行了系统阐述,以便为苹果绵蚜无公害防治技术研究和抗性品种选育提供依据。

Woolly apple aphid（Eriosoma lanigerum Hausmann）,an important quarantine insect,is native to eastern north America.It has been found around the world with the exchange of economy and the import and export of apple seedlings.Woolly apple aphid could occurred many generations in a year,so it could affect the growth of nursery trees and apple quality and creat great economic losses.It secretes some wax filaments,which make the Woolly apple aphid difficult to control.Now,woolly apple aphid has been the control emphasis in apple productive area.In this paper,the breeding of resistant hosts and non-pollution control technology were introduced to control wooly apple aphid integratedly.
