摘要：

The effect of ethanol on larva-to-pupa and larva-to-adult survival was compared in ten laboratory strains of Drosophila melanogaster. The strains had five different allele combinations at the Adh. and Odh loci. Two parallel strains of the five two-locus genotypes were isolated from different isofemale lines, and so they had different genetic backgrounds. Second instar larvae of all ten strains were exposed to different ethanol treatments and larva-to-pupa and larva-to-adult survival components were estimated. The strains with different genetic background but identical genotypic combinations at the Adh and Odh loci had different initial survival rates but they exhibited similar tolerance to ethanol. Ethanol tolerance appeared to depend predominantly on the Odh locus. The two Adh genotypes did not show significantly different ethanol tolerance. In contrast, the three Odh genotypes tolerated exogenous ethanol differently: Odh(F) homozygotes had the highest tolerance to ethanol in both the larval and pupal stages. (C) Inra/Elsevier, Paris.
