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。
Objective: To discuss the anti-mosquito mechanism of action na. Methods: The fourth instar larvae of Aedes albopictus were treated with 3 different concentrations (2.79, 1.39 and 0.70 μmol / L) of Soxhlet (cypermethrin), and the hemolymph of the newly infected female mosquitoes was collected. And control group mosquito blood lymph and amino acid content. Results: The contents of eleven elements in the lymphocytes of mosquitoes were compared between the three different concentrations of drug and the control (0.2% acetone). Compared with the control group, the contents of 8 other elements except zinc, chromium and calcium were significantly increased in the 2.79μmol / L group compared with the control group, while the levels of 1.39μmol / L and 0 .70μmol / L group were significantly higher than those in the control group Iron, manganese and other 6 - 7 elements higher than the control group. The 15 amino acids in the mosquitoes of 1.34μmol / L and 0.70μmol / L of sinotron and control (dechlorinated water) were compared, and the contents of 12 kinds of amino acids in the two groups were all decreased. Conclusion: Struggle na has some effect on the content of amino acids and elements in the hemolymph of Aedes albopictus.
