Drosophila mauritiana larvae are tolerant to ethanol as a supplementary nutritional resource at low concentrations. Higher levels of ethanol (5 per cent) in the food adversely affect larval behaviour causing reduced rates of locomotion and feeding which are associated with low larva-to-adult survival. Two codominant autosomal alleles AdhS and AdhF controlling variant electromorphs of alcohol dehydrogenase are indistinguishable in their effects on ethanol tolerance in this species. A comparison of larval behaviours shows that D. mauritiana has a lower ethanol tolerance than either of its sibling species D. melanogaster and D. simulans.
毛里求斯果蝇幼虫能够耐受低浓度乙醇，将其作为一种补充营养资源。食物中乙醇含量较高（5%）会对幼虫行为产生不利影响，导致运动和进食速率降低，这与幼虫到成虫的低存活率相关。控制乙醇脱氢酶变异电泳形态的两个共显性常染色体等位基因AdhS和AdhF，在该物种中对乙醇耐受性的影响无法区分。幼虫行为比较表明，毛里求斯果蝇的乙醇耐受性低于其同胞物种黑腹果蝇和拟果蝇。
