昆虫使用几种感官来觅食，检测花的线索，如颜色，形状，图案和挥发物。我们报告一个以前不受欢迎的感觉方式在熊蜂（熊蜂terrestris），检测花电场。这些领域作为花卉线索，这是受自然充电蜜蜂的访问。与视觉线索一样，花电场也表现出模式和结构的变化，这可以被熊蜂区分开来。我们还表明，这样的电场信息有助于复杂阵列的花卉线索，共同提高传粉者的记忆花的奖励。由于花电场可以在几秒钟内改变，这种感觉方式可能有助于花和它们的传粉者之间的快速和动态的通信。
Insects use several senses to forage, detecting floral cues such as color, shape, pattern, and volatiles. We report a formerly unappreciated sensory modality in bumblebees (Bombus terrestris), detection of floral electric fields. These fields act as floral cues, which are affected by the visit of naturally charged bees. Like visual cues, floral electric fields exhibit variations in pattern and structure, which can be discriminated by bumblebees. We also show that such electric field information contributes to the complex array of floral cues that together improve a pollinator's memory of floral rewards. Because floral electric fields can change within seconds, this sensory modality may facilitate rapid and dynamic communication between flowers and their pollinators.
