寄生虫的抗药性管理     

史喜菊  段俊秀  汪明 《中国兽药杂志》2003,37(9):41-44

抗药性在畜禽寄生虫中普遍存在，且具有一些共同的特征。了解这些共同特征将会为寄生虫的抗药性管理提供一些新观点、新思路。本文着重讨论了寄生虫的抗药性问题，并对其共同特征做了描述；同时也论述了寄生虫综合管理方案，旨在通过总结一种寄生虫的综合管理方案，为其他寄生虫病的控制开辟一条新途径。  相似文献   

晋南冬麦区大麦黄矮病毒流行株系监测及防治策略探讨   总被引：2，自引：0，他引：2  

刘艳  钱幼亭  梁影屏 《植物保护学报》2002,29(4):300-304

连续5年(1996～2000年)采集晋南冬麦区小麦黄矮病标样,采用生物学和血清学(酶联免疫吸附法)相结合的诊断方法对该地区的大麦黄矮病毒流行株系进行了鉴别。结果表明,该小麦黄矮病流行区近五年以GAV株系为主流株系,兼有少量GPV、PAV和混合株系存在。同时对小麦抗黄矮病新品种“临抗1号”进行了GPV和GAV两种株系的抗性测定,明确了该品种兼抗GPV和GAV两种株系。根据小麦黄矮病发生现状,提出了一套以选育推广抗耐病品种为主,以药剂防治为辅的综合防治措施。以期为当地小麦生产服务。  相似文献

20世纪80年代后，稻瘿蚊发生危害明显回升，损失相当严重。以大田试验示范为主，系统研究了新耕作条件下稻瘿蚊综合防治，首次总结提出“喷药除草、压低虫源、抓住晚秧、做好测报、挑治本田”的综合防治新技术体系。室内外试验和大田示范表明，应用草甘膦杀死越冬寄主游草，可显著减少虫源基数；灭线磷(商品名益舒宝)、氯唑磷(商品名米乐尔)是防治稻瘿蚊的高效药剂，抗蚊青占品种高抗稻瘿蚊。此外，合理利用杀虫植物、性引诱剂和天敌等亦是防治稻瘿蚊的重要措施。在面积达12．46万hm^2的示范推广实践中，本田防治效果均达80％以上。  相似文献

近年来,随着我国农业种植结构的调整和耕作栽培方式的转变,玉米品种选育加快,种植面积迅速增加,玉米病虫害发生一直呈加重趋势,一些次要病虫害在全国范围或局部地区为害不断加重,上升为主要病虫害,生产上还出现了一些新发病虫害,对玉米安全生产构成了威胁。本文总结了我国玉米重要病虫害的发生现状,并对发生趋势进行了分析,目前生产上的重要病虫害如亚洲玉米螟、桃蛀螟、棉铃虫以及黏虫为害加重并将持续发生;土传病害玉米茎腐病、穗腐病等危害将持续加重;风险性叶斑病玉米大斑病、南方锈病等仍在流行,未来不可忽视;还需关注未来危害性具有上升趋势的病虫害。提出了相应的防控对策。  相似文献   

Management of yellow dwarf disease in Europe in a post‐neonicotinoid agriculture     

Louise Mc Namara  Kevin Gauthier  Lael Walsh  Gaël Thbaud  Michael Gaffney  Emmanuel Jacquot 《Pest management science》2020,76(7):2276-2285

Barley/cereal yellow dwarf viruses (YDVs) cause yellow dwarf disease (YDD), which is a continuous risk to cereals production worldwide. These viruses cause leaf yellowing and stunting, resulting in yield reductions of up to 80%. YDVs have been a consistent but low‐level problem in European cereal cultivation for the last three decades, mostly due to the availability of several effective insecticides (largely pyrethroids and more recently neonicotinoids) against aphid vectors. However, this has changed recently, with many insecticides being lost, culminating in a recent European Union (EU) regulation prohibiting outdoor use of the neonicotinoid‐insecticide compounds. This change is coupled with the growing challenge of insecticide‐resistant aphids, the lack of genetic resources against YDVs, and a knowledge deficit around the parameters responsible for the emergence and spread of YDD. This means that economic sustainability of cereal cultivation in several European countries including France and United Kingdom is now again threatened by this aphid‐vectored viral disease. In this review, we summarize the current knowledge on the YDV pathosystem, describe management options against YDD, analyse the impacts of the neonicotinoid ban in Europe, and consider future strategies to control YDV. © 2020 Society of Chemical Industry  相似文献   

Sublethal effects of nine insecticides on Drosophila suzukii and its major pupal parasitoid Trichopria drosophilae

Background

Although the pupal parasitoid Trichopria drosophilae is used in conservative and augmentative biocontrol of Drosophila suzukii infestations, current pest management strategies mostly rely on multiple insecticide applications. In this context, the aim of the study was to investigate the baseline toxicity of nine insecticides on D. suzukii larvae and their multiple sublethal effects (LC₁₀) on immature stages of the pest feeding on contaminated diet and T. drosophilae developing within the intoxicated host.

Results

Chlorpyriphos and azadirachtin showed the lowest and the highest LC₁₀, the values of which were 9.78 × 10¹³ and 1.46 × 10³ times lower than their recommended label field rate, respectively. Among tested insecticides, imidacloprid, malathion and dimethoate were the only treatments that did not affect the juvenile development time of D. suzukii, while spinosad and the organophosphates chlorpyriphos and dimethoate did not influence fly pupal size. No sublethal effects were recorded on T. drosophilae degree of infestation (DI) and juvenile development time. On the contrary, cyazypyr and dimethoate negatively affected the success of parasitism (SP) and the number of progeny of the pupal parasitoid, in association with malathion for the first parameter and spinosad for the fertility. Compared to the untreated control, more female progeny emerged following azadirachtin exposure, while dimethoate caused the opposite effect. Imidacloprid, lambda-cyhalothrin and spinetoram decreased hind tibia length of emerged parasitoids.

Conclusion

This study provides new insights on the (eco)toxicological profile of nine insecticides and new information needed to support the deployment of T. drosophilae in the field within the sustainable management techniques against D. suzukii. © 2023 The Authors.

不同防治对策对柑桔糠片蚧种群的影响     

周程爱  邹建椈  欧阳志云 《植物保护学报》1992,19(1):47-52

1984—1987年在湖南桔园进行了综防对策、化防对策和自控(不采取任何人为的防治措施)等处理对柑桔主要害虫——糠片蚧种群影响的比较研究。综防区采用综合措施,刷洗主干,释放部分天敌,剪去蚧虫为害严重的枝条,冬季和夏季分别施用一次松脂合剂和矿油乳剂;化防区按常规每年喷药5—6次;结果表明:综防区全年虫口密度与化防区相近,两者均显著低于自控区;综防区糠片蚧蚜小蜂等寄生性天敌未受到明显的损害,捕食性蓟马、钝绥螨等捕食性天敌明显多于自控区;其它非生物致死因子对幼蚧的作用大于化防区,果实出口率自1986年起亦较化防区显著上升。自控区糠片蚧未得到控制,果实出口率较化防区降低13.3%—29.8%。化防区各种天敌的作用均显著下降,农药残留亦高。除自控区和化防区柑桔全爪螨为害较重外,其它害虫在各区的为害均处于较低的水平。文章还评价了在三种处理区致死因子对糠片蚧种群趋势指数的作用。  相似文献
