The Amy-locus polymorphism of Drosophila subobscura is used as a model-system for an experimental population genetic study of adaptive significance of alpha-amylase activity on substrates of different carbohydrate compositions. So far, fitness components have not commonly been included in ecological-genetic studies of alpha-amylase polymorphism in this species. In the present paper fitness components are analyzed in relation to different amylase activities in D. subobscura individuals homozygous for "slow" and "fast" Amy allele, associated with substrates of different carbohydrate compositions. The results indicate a significant effect of substrate carbohydrate composition on fitness components of the genotypes homozygous for S or F Amy allele in D. subobscura through their enzyme activity.
果蝇的Amy基因座多态性被用作一个模型系统，用于对α-淀粉酶在不同碳水化合物组成底物上的活性的适应性意义进行实验群体遗传学研究。到目前为止，在该物种α-淀粉酶多态性的生态遗传学研究中，适应性成分通常未被纳入。在本文中，对果蝇中与不同碳水化合物组成底物相关的“慢”和“快”Amy等位基因纯合个体的不同淀粉酶活性的适应性成分进行了分析。结果表明，底物碳水化合物组成通过其酶活性对果蝇中S或F Amy等位基因纯合基因型的适应性成分有显著影响。
