昆虫需要B族维生素的饮食来源，但相对而言，人们对它们是否以调节其他营养素的方式调节B族维生素摄入量知之甚少。蜜蜂主要通过采集花粉来满足其维生素B的需求。采用营养学的几何框架，我们发现蜜蜂主动调节其维生素摄入量，遵循Bertrand规则。我们用必需氨基酸（EAA）和碳水化合物（C）的饮食喂养蜜蜂，以确定B族维生素的添加如何影响这些常量营养素的调节。在我们的实验中，蜜蜂更喜欢浓度与蜜蜂食物（花粉、蜂饼和皇家浆）中的维生素相当的维生素。蜜蜂主动调节烟酸在最佳值附近。补充B族维生素的蜜蜂饮食影响EAA和碳水化合物摄入量的不同，这取决于维生素的类型。这些维生素的影响是在7天的过程中观察到的，其中蜜蜂的死亡率在低和中等叶酸浓度的饮食中增加。这项研究提供了蜜蜂食物摄入调节和喂养偏好的见解，并为未来研究蜜蜂饮食中的B族维生素奠定了基础。
Insects require dietary sources of B-vitamins, but relatively little is known about whether they regulate B-vitamin intake in the same way they regulate other nutrients. Honey bees meet their B-vitamin requirements mainly from the pollen they collect. Employing the geometric framework for nutrition, we found that honey bees actively regulate their vitamin intake following Bertrand's rule. We fed bees with a diet of essential amino acids (EAAs) and carbohydrate (C) to identify how the addition of B-vitamins affected the regulation of these macronutrients. In our experiments, honey bees preferred vitamins in concentrations comparable to those found in honey bee food (pollen, beebread, and royal jelly). Honey bees actively regulated niacin around an optimal value. Supplementing honey bee diets with B-vitamins influenced the amount of EAAs and carbohydrate ingested differently depending on the type of the vitamin. The impact of these vitamins was observed over the course of seven days where honey bees' mortality increased on diets of low and medium folic acid concentrations. This study provides insights into honey bee food intake regulation and the feeding preferences and sets the basis for future studies considering B-vitamins in honey bees diets.
