我们制备了上海,广西和郑州三株中华按蚊、江苏和广西两株嗜人按蚊的基因组DNA,分别用BglⅡ,HaeⅢ和Pst Ⅰ消化各基因DNA,琼脂糖凝胶电泳,溴乙啶染色后,观察比较同种各株间基因组DNA重复序列DNA的限制酶切长度差异。结果发现,各地理株间的酶切引型,既具有种的特征,主带相同,稳定; We prepared genomic DNA of three Anopheles anthropophagus, Anopheles sinensis, Jiangsu and Guangxi strains in Shanghai, Guangxi and Zhengzhou, and digested the DNA of each gene with BglII, HaeIII and PstI, respectively. The agarose gel electrophoresis and ethidium bromide After the observation, we compared the DNA restriction endonuclease length of genomic DNA between the same species. The results showed that the enzyme digestion patterns among the various geographic strains have both the characteristics of the species, the same main, stable;
