地面炸弹蜂的觅食者能够提醒它们的同伴食物来源的存在。据推测，这至少部分是通过巢内信息素的分布来实现的。我们通过行为测试证实了这一说法，在行为测试中，警报信号通过长途航空运输从一个群体传播到另一个群体，因此排除了所有其他信息交换方式。然后，我们调查了信息素的来源，并能够证明从大黄蜂工蜂的红土V-VII中提取的己烷提取物引起了更高的活性，就像一个成功的觅食者一样。其他腺体的提取物，如下颌、唇、下咽和杜福尔腺，以及角质层其他部位的提取物没有效果。这表明，大黄蜂拥有一种信息素分泌腺，类似于蜜蜂的纳萨诺夫腺。事实上，蜜蜂纳萨诺夫腺的提取物也被证明能引起大黄蜂工蜂的注意，这表明这些腺体可能是同源的。
Foragers of Bombus terrestris are able to alert their nestmates to the presence of food sources. It has been supposed that this happens at least partially through the distribution of a pheromone inside the nest. We substantiate this claim using a behavioral test in which an alerting signal is transmitted from one colony to another by long distance air transport, so excluding all other modalities of information exchange. We then investigated the source of the pheromone and were able to show that a hexane extract from tergites V-VII of bumble bee workers elicits higher activity, like a successful forager does. Extracts from other glands, such as the mandibular, labial, hypopharyngeal, and Dufour's gland as well as extracts from other parts of the cuticle had no effect. This suggests that bumble bees possess a pheromone-producing gland, similar to the Nasanov gland in honey bees. Indeed, an extract from the honey bee Nasanov gland also proved to alert bumblebee workers, suggesting a possible homology of the glands.
