Parental (transgenerational) effects occur when the conditions experienced by a mother or father contribute to offspring phenotype. Here we show that parental larval diet in mosquitoes, Aedes aegypti, results in differential allocation of resources in offspring of parents depending on the nutritional condition (quality) of their mate. Maternal effects influenced the number of eggs produced by females as well as their lipid investment. Low nutrient females mated with high nutrient males laid eggs with significantly higher lipid content than those laid by high nutrient females. Paternal effects showed that when high nutrient males mated with low nutrient females, resulting eggs had higher lipid content than when low nutrient males mated with low nutrient females. Overall, our results are consistent with a pattern predicted by the differential allocation of resources hypothesis, when females experience nutritional deprivation, which asserts that mate quality directly influences reproductive allocation.
当母亲或父亲所经历的条件促成后代表型时，就会发生亲代（跨代）效应。在这里，我们表明，在蚊子埃及伊蚊中，亲代幼虫的饮食会根据其配偶的营养状况（质量）导致后代资源分配的差异。母体效应影响雌性产生的卵子数量及其脂质投资。与高营养雄性交配的低营养雌性所产的卵子的脂质含量明显高于高营养雌性所产的卵子。父体效应表明，当高营养雄性与低营养雌性交配时，所产生的卵子的脂质含量高于低营养雄性与低营养雌性交配时。总的来说，我们的结果与资源差异分配假说所预测的模式一致，即当雌性经历营养剥夺时，配偶质量直接影响生殖分配。
