摘要：

Based on data from 70 literature sources, the frequencies of common alleles at six allozyme loci were examined in Drosophila melanogaster populations from five geographic regions: North America (including Central America), South America, Europe-Africa, Asia, and Australasia. The analyzed loci were Adh, Odh, Gpdh, G6pd, Pgd, and Est-6, which have been previously reported by other authors to show latitudinal variation in North America, Eurasia and Australasia. We found five parallel latitudinal dines for Adh(F) and three dines for Gpdh(S) in five geographic regions as well as four dines for G6pd(F), three dines for Est-6(S), and two dines for Odh(F) and Pgd(F) in four regions (data from South America for G6pd, Odh, Est-6, and Pgd were not available). Such pattern of variation confirmed the possibility that considered allozyme polymorphisms are maintained by climatic selection. Significant differentiation of mean allele frequencies among geographic regions was in agreement with current evidence on history of D. melanogaster worldwide dispersion.
