A few hours in high temps reduced the ability of antennae to detect flower scents by 80 percent. That could impact the bees’ ability to find food.
Proceedings of the Royal Society BWhat do you want to know about extreme heat and how it can lead to extreme weather events?
After the simulated heat waves, the researchers cut off the bees’ antennae, which the insects use to smell, and measured whether the olfactory sensory neurons in the antennae were still able to detect chemical compounds common in many flowers, called flower scents.
