Scientists have wondered how bees interact with signals emitted by flowers until a recent study demystified the process. Flowers transmit signals to insect pollinators and scientists now have evidence that small vibrating hairs on bees give them the ability to communicate.
Scientists are trying to understand the process of how floral signals are perceived because bees play an essential role as pollinators of major crops.
Researchers with the University of Bristol analyzed bees’ nervous systems and discovered that only their hairs informed their nervous system of the signal. They used lasers to record the vibrations and found that both the bees’ antennae and hairs respond to an electric field. Researchers surmise that this process—electroreception—may be more prevalent in other insects as well.
Properties of the bees’ hairs being lightweight and stiff produce an acoustic motion similar to spider hairs and mosquito antennae. Lead researcher, Dr. Gregory Sutton, a Research Fellow with the University of Bristol’s School of Biological Sciences, said, “We were excited to discover that bees’ tiny hairs dance in response to electric fields, like when humans hold a balloon to their hair. A lot of insects have similar body hairs, which leads to the possibility that many members the insect world may be equally sensitive to small electric fields.”
These relationships inform scientists of the evolution of flowers and pollinators enlightening current knowledge of our ecosystem. Electroreception also exists in aquatic life. Sharks, for instance, are designed with jelly-infused receptors that detect gyrations in electric fields, which clues them into surrounding prey.
The findings were published today in the international journal Proceedings of the National Academy of Sciences (PNAS).
