国外甜菜孢囊线虫发生危害、生物学和控制技术研究进展

摘要

The sugar beet cyst nematode,Heterodera schachtii ,is one of the important quarantine nematodes worldwide.It is a major pest on sugar beet and cause serious economic loss,occurred and distributed in more than 50 countries and regions and has been recognized as quarantine nematode within 22 countries.H .schachtii infects over 218 plant species within 95 genera from 23 different plant families.The yield losses caused by H .schachtii were estimated to be 25%-70%.In European countries,the annual yield losses were estimated at 90 million Eu-ros.H .schachtii is also one of the important quarantine nematodes in China due to its devastating damage to sugar beet.Furthermore,the risk assessment results indicate that H .schachtii could occur at the major sugar beet grow-ing areas in North China.Therefore,this nematode should be paid attention by agricultural administrative depart-ments of our country,and strict precautions should be taken against the occurrence and outbreak of this nematode in our country.This paper describes the research progress of foreign sugar beet cyst nematodes.%甜菜孢囊线虫(Heterodera schachtii Schmidt)是全世界重要检疫性有害生物,对甜菜具有毁灭性危害,该线虫已在全世界50多个国家或地区有分布,22个国家将其列为检疫对象。甜菜孢囊线虫寄主多达23科95属218种植物,可导致甜菜产量损失达25%~70%,甚至绝产,在欧洲每年造成的经济损失已超过9000万欧元,严重威胁当地甜菜生产和制糖业。甜菜孢囊线虫是我国重要进境检疫性有害生物,因其对甜菜具有毁灭性危害,我国各级农业行政主管部门对甜菜孢囊线虫都高度重视,严防该线虫的暴发和危害,本文介绍国外甜菜孢囊线虫研究进展。
