熊蜂（Bombus terrestris）是一种储存花粉的大黄蜂，它的幼虫依赖于工蜂的逐步供应。我们测试的假设，幼虫表皮化学物质可以作为饥饿信号。我们首先展示了一个新的经典条件反射实验，使用Y形管，工人可以训练，喜欢的提取物正常喂养的幼虫比那些饥饿的幼虫。这证明了工蜂区分幼虫提取物的能力。其次，我们在生物测定中表明，工人也使用这些感知的差异，根据他们的营养状况喂养幼虫。幼虫育雏喷洒的饥饿幼虫的提取物喂养显着超过幼虫育雏喷洒的提取物，正常喂养的幼虫或溶剂（正戊烷）。因此，我们得出结论，B。terrestris幼虫通过它们的表皮化学物质发出它们对食物的需求信号，并讨论了这种通信形式在多大程度上可以给幼虫一些控制它们发育的能力。
Larvae of Bombus terrestris, a pollen-storing bumblebee, are dependent on progressive provisioning by workers. We test the hypothesis that larval cuticular chemicals can act as a hunger signal. We first show with a new classical conditioning experiment, using a Y-shaped tube, that workers can be trained to prefer the extracts of normally fed larvae over those of starved larvae. This proves the ability of workers to discriminate between larval extracts. Second, we show in a bioassay that workers also use these perceived differences to feed larvae according to their nutritional status. Larval broods sprayed with the extracts of the starved larvae were fed significantly more than larval broods sprayed with the extracts of normally fed larvae or with the solvent (n-pentane) only. We therefore conclude that B. terrestris larvae signal their need for food via their cuticular chemicals, and discuss the extent to which this form of communication could give larvae some control over their development.
