饲料质量对动物的发育和生存至关重要。真菌可以为无法合成它们的生物体提供必需的营养素，例如黑腹果蝇中的麦角固醇。果蝇研究检查饮食中酵母质量的影响，通常在整个生命周期（幼虫到成虫）或在成虫阶段提供饮食，很少关注幼年饮食。在这里，我们测试了幼虫饮食中酵母质量对成虫前发育和成虫体重，存活，繁殖和食物偏好的影响。将酵母酿酒酵母以三种形式在三种处理中（活的、加热的或干燥的）添加到用作幼鱼饮食的食物中或不添加（空处理）。由这四种幼虫饲料饲养的幼虫产生的成虫都保持在类似的标准实验室食物饲料上。我们的数据表明，酵母质量的青少年饮食影响幼虫到蛹，但不是蛹到成人的发展。重要的是，成年人的生存，食物偏好，交配行为和角质层信息素强烈不同的少年饮食。因此，酵母质量的变化在成年前的果蝇饮食影响关键的成年生活特征，涉及食物搜索，繁殖和生存。
Diet quality is critical for animal development and survival. Fungi can provide nutrients that are essential to organisms that are unable to synthetize them, such as ergosterol in Drosophila melanogaster. Drosophila studies examining the influence of yeast quality in the diet have generally either provided the diet over the whole life span (larva to adult) or during the adult stage and have rarely focussed on the juvenile diet. Here, we tested the effect of yeast quality in the larval diet on pre-adult development and adult weight, survival, reproduction and food preference. The yeast Saccharomyces cerevisiae was added in three forms in three treatments—live, heated or dried—to food used as the juvenile diet or was not added (empty treatment). Adults resulting from the larvae raised on these four juvenile diets were all maintained on a similar standard laboratory food diet. Our data indicate that yeast quality in the juvenile diet affects larva-to-pupa—but not pupa-to-adult—development. Importantly, adult survival, food preference, mating behaviour and cuticular pheromones strongly varied with the juvenile diet. Therefore, the variation of yeast quality in the pre-adult Drosophila diet affects key adult life traits involved in food search, reproduction and survival.
