用Feulgen细胞光度法测定23种伊蚊的单倍体核DNA差异达3倍。这伴随着总染色体长度的2倍变异。这两个参数之间存在显著相关（r= 0.765， P< 0.001）。10株白纹伊蚊的基因组大小在0.87 ~ 1.3 pg之间，分布范围广。在伊蚊中，染色体DNA数量的大规模差异伴随着物种形成和进化。
Haploid nuclear DNA of 23 species of Aedes, as determined by Feulgen cytophotometry, was found to vary 3-fold. This was accompanied by a 2-fold variation in total chromosomal length. There was a significant correlation (r= 0· 765, P< 0· 001) between these two parameters. Genome size varied from 0· 87 pg to 1· 3 pg among 10 strains of Aedes albopictus, from wide geographic regions. Large scale differences in chromosomal DNA amounts have accompanied speciation and evolution in aedine mosquitoes.
