【摘要】 为及时掌握柑橘全爪螨的抗性水平， 指导柑橘害虫化学防治， 保证橘园经济效益， 采用联合国粮农组织推荐的玻片浸渍法测定了９ 种农药对浙江省柑橘全爪螨的毒力。结果表明： 柑橘全爪螨对多种农药产生了程度不同的抗药性。对水胺硫磷抗性水平为极高抗（ 衢县航埠） ； 对三氯杀螨醇、螨克、灭扫利和霸螨灵（ 衢县航埠） ， 哒螨净（ 黄岩） ， 水胺硫磷（ 龙游西方坞、上吁头和溪口） ， 灭扫利（ 龙游西方坞和上吁头） 为高抗； 对水胺硫磷（ 黄岩） ， 三氯杀螨醇（ 龙游西方坞、上吁头和溪口） ， 螨克（ 龙游西方坞和溪口） ， 氧化乐果（ 衢县航埠） ， 灭扫利（ 龙游溪口） 为中抗； 对螨克（ 黄岩） ， 氧化乐果（ 龙游西方坞和溪口） ， 功夫菊酯（ 衢县航埠） ， 哒螨净（ 龙游西方坞） ， 尼索朗（ 衢县航埠） 为低抗； 对三氯杀螨醇（ 黄岩） ， 功夫菊酯和霸螨灵（ 龙游西方坞） 有耐药性； 对功夫菊酯（ 龙游溪口） ， 尼索朗（ 龙游西方坞） 和哒螨净（ 衢县航埠） 敏感。研究还表明： 柑橘全爪螨对拟除虫菊酯类农药易产生抗药性， 相互间具有交互抗性。而对三氯杀螨醇的抗药性发展较缓慢， 敏感性恢复较快。对霸螨灵和哒螨净等杂环类农药极易产生抗药性， 但抗药性消除也较快。对螨克等更多还原

【Abstract】 In order to timely understand the resistance of Panonychus cotri ,guide chemical control and guarantee the economic benefit of the citrus gardens,the toxicity of 9 pesticides for this insect in Zhejiang was measured by means of slide maceration recommended by FAO of the United Nations.Results obtained show that Panonychus cotri on citrus has created resistance to a number of pesticides to various extents.Isocarbothos was most highly resisted by the pest in Hangbu of Quxian County;Dicofol,amitraz,fenpropathrin and fentyroximate applied in Hangbu of Quxian,pyridaben applied in Huangyan City,isocarbothos applied in Xifangwu,Shangyutou and Xikou of Longyou County,and fenpropathrin applied in Xifangwu and Shangyutou of Longyou were highly resisted;Isocarbothos used in Huangyan,dicofol used in Xifangwu,Shangyutou and Xikou of Longyou,amitraz used in Xifangwu and Xikou of Longyou,omethoate used in Hangbu of Quxian,and fenpropathrin used in Xikou of Longyou were also resisted;Amitraz adopted in Huangyan,omethoate adopted in Xifangwu and Xikou of Longyou,cyhalothrin adopted in Hangbu of Quxian,pyridaben adopted in Xifangwu of Longyou,and hexythiazox adopted in Hangbu of Quxian were lowly resisted;Dicofol applied in Huangyan,and cyhalothrin and fentyroximate applied in Xifangwu of Longyou were highly tolerated by the pest,but the pest was sensitive to cyhalothrin applied in Xikou of Longyou,hexythiazox applied in Xifangwu of Longyou and pyridaben applied in Hangbu of Quxian.Studies also show that its easy for Panonychus cotri to develop resistance to such pesticides as pyrethroid and the pest and pesticides have inter resistance.The resistance to dicofol develops slowly and sensitivity resumes quickly.The resistance to such pesticides of heterocycle as fentyroximate and pyridaben either easily forms but disappears slowly.The strategies in resistance management of Panonychus cotri is suggested finally.更多还原
