摘要: 在室内,利用速灭杀丁、叶蝉散、杀虫双、乐果、三氯杀螨醇、草苷膦等6种农药对海南山蛭(Haemadipsahainana)进行毒力测定,比较各种农药LD50表明,速灭杀丁>叶蝉散>三氯杀螨醇>杀虫双>乐果.除草剂草苷膦对海南山蛭完全无毒杀作用.“草苷膦+速灭杀丁”对海南山蛭仍有很强的毒杀作用.海南山蛭对速灭杀丁的敏感性为,成体>幼体>亚成体.在田间小区试验表明,1.5%速灭杀丁防治效果为95.08%,大面积应用表明“草苷膦药液+0.5%速灭杀丁”防治效果最好,达94.74%,“草苷膦药液+1%叶蝉散乳油”防治效果次之,达90.5%.“草苷膦+灭蛭农药”是防治山蛭好药剂,达到灭蛭除草的目的.

Abstract: Laboratory determination on the toxicity of sumicidin,isoprocarb,dicofol,thiocyclam,dimethoate and glyphosate to Haemadipsa hainana showed that LD 50 for the six pesticides followed the order of sumicidin>isoprocarb>dicofol>thiocyclam>dimethoate,but glyphosate was not virulent.“Glyphosate+sumicidin”had much more toxicity.The susceptibility of H.hainana to sumicidin differed in the order of adult>juvenile>subadult.Field tests showed that the control effect of 1.5% sumicidin to H.hainana was 95.08% of total number of its population.Applied tests showed that the control effect of “Glyphosate+0.5% sumicidin” was 94.7%,and “glyphosate+1% isoprocarb”was 90.5%.“Glyphosate+pesticides”was more effective both in controlling H.hainana and in destroying its habitat weed.
