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0.70 μmol/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2.79 μmol/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1.39 μmol/L 和0.70 μmol/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1.39 μmol/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。

Abstract:

AIM: To explore the mechanism of the mosquitocidal effect of Fendona. METHODS: The fourth instar larvae of Aedes albopictus were treated with different concent rations 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 elements including Fe, Zn, Cu, Cr, K, Na, Ca, Mg, S, P in three different concentrations (0.70, 1.39 and 2.79 μmol/L) of Fendona-treated groups and control group (0.2% acetone-treated) were compared. RESULTS: Compared to the control group, there was a significant increase in the contents of 8 kinds of elements except for Zn, Cr and Ca in the 2.79 μmol/L group; while in 1.39 μmol/L and 0.70 μmol/L groups, the contents of Fe, Mn, K and Mg were higher than those in the control group. Comparing the contents of 15 kinds of amino acids in hemolymph among 1.39 μmol/L, 0.70 μmol/L Fendona and the control group, the levels of 12 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 Aedes albopictus.
