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 (Haemadip sahainana)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 .0 8% ,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 .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.
