为了了解大黄蜂群落中的资源分配，我们分析了各种形态特征。对熊蜂(Bombus Ardens)、伪熊蜂(B. quacita)、大黄蜂(B. Diversus)、大黄蜂(B. igiguts)、本州大黄蜂(B. honShusis)和大黄蜂(B. beaticola)6种熊蜂的1 2 69只个体进行了主成分分析，结果表明，大黄蜂的主成分分析结果表明，这6种熊蜂有明显的区别。舌长、前舌长和头长与第二组分呈正相关，鼻子越长，身体越窄，这可能有助于蜜蜂侵入和获取深层蜜源。具长鼻子和窄体形的Bombus disdicsus偏爱花冠管较长的花，而具短喙和宽体的B. quiscita和B. Ignius则访问有短花冠或盘状花朵的花。具有相似形态特征的两对同属植物B. ardens和B. beaticola，以及B. Guiscita和B. Igntes，通过生境选择和季节划分来划分花卉资源。对于熊蜂物种之间的资源分配，不仅是形态因素，还包括其他因素，如栖息地和季节偏好、花的使用、觅食行为和种间相互作用。
To understand resource partitioning in a bumblebee community, we analyzed various morphological characters. A total of 1269 individuals of six bumblebee species, Bombus ardens, B. hypocrita, B. diversus, B. ignitus, B. honshuensis and B. beaticola, were examined and principal component analysis showed that the bumblebee species were clearly differentiated. Glossa, prementa and head lengths were positively correlated with the second component, and a longer proboscis was associated with a narrower body, which may help bees to intrude into and access deep‐lying nectar sources. Bombus diversus, with a long proboscis and narrow body, preferred flowers with a long corolla tube, whereas B. hypocrita and B. ignitus, which have short proboscises and wide bodies, visited flowers with short corollas or dish‐shaped flowers. Two pairs of consubgeneric species that have similar morphological characteristics, B. ardens and B. beaticola, and B. hypocrita and B. ignitus, divided flower resources by habitat selection and seasonal partitioning. For resource partitioning among bumblebee species, not only morphology but also other factors, such as habitat and seasonal preference, flower use, foraging behavior, and interspecific interactions, are responsible.
