摘要：本文描述了一项关于熊蜂幼虫食物成分与雌性种姓发育之间关系的研究。第一个目的是评估幼虫饮食中腺体分泌物作为参与幼虫摄食和种姓分化的可能因素的重要性。发现在摄入蔗糖期间添加了少量蛋白质分泌物，但在向幼虫排出食物时没有添加。讨论这些分泌物具有消化功能，而不是食品添加剂，可能在种姓分化过程中发挥作用。¶其次，对不同种姓、不同年龄、群体社会发展不同时期的幼虫食物样本的总体成分进行了比较分析。不同种姓或不同年龄组之间花粉、蔗糖和蛋白质总量没有显着差异。与工蜂不同的是，熊蜂工蜂个体并没有根据自己的年龄或蜂群的社会发展来改变它们为蜂巢提供的饮食成分。这些发现表明，所有幼虫在其总体发育过程中都接受相同的营养，并表明蜂王幼虫和工蜂幼虫之间的发育差异既不是由变异引起的，也不是由它们的食物在花粉、蛋白质和碳水化合物含量方面的质变引起的。
Summary: This paper describes a study on the relation between the composition of larval food and the development of female castes in bumblebees. The first aim was to evaluate the significance of glandular secretions in the larval diet as a possible factor involved in larval feeding and caste differentiation. Small amounts of proteinaceous secretions were found to be added during the ingestion of sucrose but not while discharging food to the larvae. It is discussed that these secretions are digestive in function rather than food additives that would possibly play a role in the process of caste differentiation.¶Secondly, a comparative analysis was made of the general composition of food samples obtained from larvae of different castes and ages and from various periods in the social development of the colony. No significant differences in the total amount of pollen, sucrose and protein were detected between the castes or different age groups. Unlike honeybee workers, individual bumblebee workers did not change the composition of the diet they supplied to the brood in relation to their own age, nor to the social development of the colony. These findings suggest that all larvae receive the same nourishment during their total development and indicate that differences in development between queen larvae and worker larvae are neither caused by variations nor by a qualitative modification of their food with respect to the amount of pollen, protein and carbohydrates.
