Cross-activity of honeybee queen pheromones in bumblebees provides evidence for sensory exploitation
<p>The evolutionary origin of queen pheromones, which regulate reproductive division of labor in insect societies, has been explained by two evolutionary scenarios: the <i>sender-precursor hypothesis</i> and the <i>sensory exploitation hypothesis</i>. These scenarios differ in terms of whether the signaling system was built on preadaptations on the part of either the sender queens or the receiver workers. While some social insect queen pheromones – such as cuticular hydrocarbons – were likely derived from ancestral fertility cues and evolved according to the former theory, the honeybee's queen mandibular pheromone (QMP) has been suggested to act directly on pre-existing gene-regulatory networks linked with reproduction. This is evidenced by the fact that QMP has been shown to also inhibit ovary activation in fruit flies, thereby implying exploitation of conserved physiological pathways. To verify whether QMP has similar effects on more closely related eusocial species, we here tested for QMP cross-activity in the bumblebee <i>Bombus terrestris</i>. Interestingly, we found that the non-native QMP blend significantly inhibited egg-laying in both worker and queen bumblebees and caused accompanying shifts in ovary activation. The native bumblebee queen pheromone pentacosane, by contrast, only inhibited the reproduction of the workers. Overall, these findings support the hypothesis that honeybee QMP likely evolved via a route of sensory exploitation. We argue that such exploitation could allow social insect queens to produce compounds that manipulate the workers to remain sterile, but that a major hurdle would be that the queens themselves would have to be immune to such compounds.</p>
