In 1982,two field strains of cotton aphid,Aphis gossypii Glov.,werecollected from Dongtai County and Jiangpu County of Jiangsu Province,and testedwith eight insecticides by means of topical application method,recommendedby The Animal Research Institute of Academia Sinica.A mierocapillary app-licator,calibrated to 0.02-0.04μl.(by use of High Speed TLC Scanner,CS-920),was used to apply droplet of insecticide solution to the dorsum of the testinsect.The toxicity baseline for each insecticide to apterous adult aphids wereobtained.The results showed that both aphid strains collected from two localitieshad developed comparatively high resistance to the organophos phorus insecti-cide-dimethoate.The LD_50 values of dimethoate for the cotton-aphid strainsin Dongtai County and Jiangpu County were 0.247 and 0.242μg/aphid,respec-tively.The resistant capacity increased at least 120-fold,as compared with thetoxicity data obtained by Zhang(1982),who used the same test method for asusceptible strain(LD_50=0.00198μg/aphid).The order of the toxicity of thetest insecticides could be arranged as follows:decamethrin>permethrin>methamidophos>methyl parathion>parathion>tsumacide>malathion>dimeth-oate.Furthermore,some of the improvements in test method for aphids'resis-tance are discussed.

1982年在江苏省东台县及江浦县,根据中国科学院动物研究所推荐的点滴法,用八种杀虫剂对田间的棉蚜(Aphis gossypii Glov)进行了毒力测定。使用的微量毛细管点滴器的标化容积为0.02—0.04微升(用高速薄层扫描仪—CS-920测定),滴施杀虫剂溶液在蚜虫的背板上,最后得到每种药剂对无翅成蚜的毒力基线。测定的结果表明东台及江浦两地田间的棉蚜已经对有机磷杀虫剂—乐果产生了较高的抗药性。两地棉蚜对乐果的 LD_(50)值分别为0.247及0.242微克/蚜,如果与张桂林(1982)发表的用同样方法测定的敏感蚜系(LD(50)=0.00198微克/蚜)相比较,东台及江浦两地的棉蚜对乐果的抗性至少是120倍。测试的杀虫剂对棉蚜的毒力次序排列如下:溴氰菊酯>二氯苯醚菊酯>甲胺磷>甲基对硫磷>对硫磷>速灭威>马拉硫磷>乐果。此外,本文对棉蚜抗药性测定方法的改进作了进一步探讨和建议.

Dimehypo macro-granule 5G is a new pesticide formulation developed by Institute of Plant Protection,GAAS,8mm in diameter, 0.3-0.6g in average weight and flat-spherical in shape. It was shown that the paddy field must be kept flooded more than one day after dimehypo granule application to provide effective results in controlling rice stem borer(Chilo suppressalis Walker), yellow borer(Scirpophaga incertulas Walker) and rice thrips(Boliothrips biformis Bagnall). Dimehypo 5G is confirmed safe to the ecosystem(such as: silk worm, arachnid, fish and aquatic animals, etc.) and labour-saving. The application method described in this paper is considered to be one of the effective measures inIPM system.

杀虫双大粒剂系中国农科院植保所研制的新剂型,含有效成分5%,扁圆形颗粒,粒径8毫米,粒重0.3—0.6克。经1982—1985年水泥池及田间试验表明:稻田保水1天以上是杀虫双大粒剂发挥药效的技术关键;它对稻螟类和稻蓟马防效优异;对生态环境(天敌蜘蛛、鱼、蚕、糙米中残留等)的影响小;撒施大粒剂比常量喷雾提高工效约16倍,减经了劳动强度;对稻田有益生物无害;杀虫双大粒剂在稻田的应用,为稻田害虫综合防治提供一种有效的手段。

A novel formulation of insecticide and application method for the control of Chilo sup-pressalis (Walker) and Tryporysa incertulus (Walker) is presented and compared with conventional methods. Dimehypo, S, S-(2-(dimethylamino)-l,3-propanediyl) disodium thiosulfa-te, is an insectidide now developed in China and has been formulated as big grannies (dime-hypo jumbo) containing 5% a.i. and in size of about 2000 granules per kilogram. Under an application rate of 15 io 18.5 kilograms per hectare, dimehypo jumbo would provide high efficacy in stem borer control, better than BHC, carbofurati and chlorodimeform which are condemned as being persistent or insecticide.: with high mammalian toxicity. Large scale field tral on 17,763 hectares of paddy fields have been conducted at seveu counties and three statefarms in Hubet Province in 1985, and high effectiveness of borer control reaches 84.5......100%. At economical rates the effectiveness could be kept as long as two weeks, but the granules must be applied within 3-4 days after the majority of the larvae having borel into the rice stems. The economic, ecological and social benefits of this new method are here evaluated.

本文报告一种防治水稻螟虫的杀虫双新剂型和使用效果。含有效成份5%的杀虫双大粒剂,每公斤含2000粒左右,在每亩1—1.25公斤的用量下,药效显著优于六六六、呋喃丹及杀虫脒等残留和高毒性农药。处理一亩田只需数分钟。在七个县和四个农场共266440亩稻田的示范试验中,防治效果达84.5—100%。杀虫双在田水中扩散迅速,24小时内即可扩散分布到全田。持效期较长,可达两周之久。但在蝗虫已蛀入稻茎后施用大粒剂,有效施药期只有3—4天。本文对杀虫双大粒剂的使用技术进行了经济效益、社会效益和生态效益方面的评价。
