摘　　要：目的 :对奋斗呐灭蚊作用机理进行探讨。方法 :以 3种不同浓度 ( 2 .79,1.39与 0 .70μmol/ L )奋斗呐 (顺式氯氰菊酯 )处理白纹伊蚊 4龄幼虫 ,并收集初羽化雌蚊血淋巴 ,分别检测奋斗呐组和对照组的蚊血淋巴元素和氨基酸含量。结果 :比较 3种不同浓度用药组与对照组 ( 0 .2 %丙酮 )蚊血淋巴中 11种元素的含量。表明 2 .79μmol/ L浓度用药组与对照组相比 ,除锌、铬、钙外 ,其他 8种元素含量均显著增高 ;而 1.39μmol/ L和 0 .70μmol/ L组与对照组相比 ,铁、锰等 6- 7种元素含量较对照组高。比较 1.39μmol/ L和 0 .70 μmol/ L奋斗呐组与对照组 (去氯水 )蚊血淋巴中 15种氨基酸含量 ,2个用药组中的 12种氨基酸含量均降低。结论 :奋斗呐对白纹伊蚊成蚊血淋巴中的元素和氨基酸的含量均有一定影响。AIM:To explore the mechanism of the mosquitocidal effectof Fendona.METHODS:The fourth instar larvae of Aedesalbopictuswere treated with different concentrations of Fendona (alphamethrin) .The hemolymph was collected from early emerged female mosquitoes and then subjected to the detection of chemical elements and amino acids.The contents of ele- ments including Fe,Zn,Cu,Cr,K,Na,Ca,Mg,S,P in three different concentrations(0 .70 , 1 .39and2 .79μmol/L) of Fendona- treated groups and control group(0 .2 % acetone- treated) were compared.RESUL TS:Compared to the control group,there was a significant increase in the contents of8kinds of elements except for Zn,Cr and Ca in the2 .79μmol/L group;while in 1 .39μmol/L and 0 .70μmol/L groups,the contents of Fe,Mn,K and Mg were higher than those in the control group.Comparing the contents of1 5 kinds of amino acids in hemolymph among1 .39μmol/L,0 .70 μmol/L Fendona and the control group,the levels of1 2 kinds of amino acids in Fendona groups were decreased.CONCLUSION:Fendona does influence the contents of many kinds of elements and amino acids in the hemolymph of adult Aedesalbopic- tus.
