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 .
In laboratory, Haemadip sahainana was tested for its virulence using 6 pesticides, such as daphnidochole, leafhopper, pest control, dimethoate, dicofol, glyphosate, Kill Ding> leaf cicada scattered> dicofol> insecticidal double> dimethoate. Herbicide glyphosate of Hainan Hirudo completely non-toxic to kill. “Glyphosate + speed kill K” is still very strong on the Hainan mountain leeches The sensitivity of M. japonicus to Oxymatrine was adult, juvenile> sub-adult.The test in field plots showed that the control efficacy of 1.5% Omeprazole was 95.08%, and the large area application showed “Glyphosate + 0.5% Oxytetracycline kill” the best control effect, up to 94.74%, “glyphosate Phospho + 1% leaf cicada scattered cream” control effect of the second, up 90.5%. “Glyphosate + Extinguishant pesticides” is to prevent and cure mountain Hirudo good agent, to achieve the purpose of exterminating weeds.
