三地理株白纹伊蚊与致倦库蚊贵州株蛋白质分析

目的：比较海南、北京、贵州三地理株白纹伊蚊和贵州株致倦库蚊蛋白质含量的差异。方法：用凯氏定氮法测定羽化后第5天白纹伊蚊和致倦库蚊（雌蚊）蛋白质含量，并比较地理株和种间的差异。结果：海南株蛋白质分别与北京株及贵州株蛋白质有显著差异（P＜0．01），但北京株与贵州株之间无显著差异（P＞0．05）；贵州株和北京株白纹伊蚊与贵州株致倦库蚊之间无显著差异（P＞0．05）；海南株白纹伊蚊与贵州株致倦库蚊之间有显著差异（P＞0．01）。结论：不同地理株白纹伊蚊蛋白质含量可有差异，同一地区的不同蚊种之间蛋白质可无差异。

A Comparative Study on Protein Contents in Three GeographicStrains of Aedes albopictus and Guizhou Strain ofCulex pipiens quinquefasciatus

Objective:To compare the contents of protein in Aedes albopictus from Beijng city?Hainan province?Guizhou province and the Guizhou strain of Culex pipiens quinquefasciatus Methods:The contents of protein were determined with Kyeldanh's method for nitrogen content determination on the 5 th day after the eclosion of the mosquitoes Results:There was a significant differenec in protein contents among Ae.albopictus strains from Hainan, Beijing,and Guizhou (P<0.01).But there was no significant difference between Beijing and Guizhou strains (P>0.05).There was no significant different protein contents between Ae.albopictus from Guizhou,Beijing and Cx.Pipiens quinquefesiatus (P>0.05).There was a significant difference in protein between Hainan strain of Ae .alopictus and Guizhou strain of Cx.pipiens quinquefasciatus (P>0.01).Conclusion:There could be differences of protein contents in different geographic strains of Ae .albopictus;There couldn't be difference of protein content in different mosquito races in th same area.
