The complexity continues to the brain, the team found. “In mosquitoes, we saw a lot of overlap in the brain,” says Margaret Herre, the co-author of the study.

Meg Younger, a former postdoc in Vosshall’s lab and now an assistant professor at Boston University made a surprising discovery. Although the 1:1:1 rule dictated that mosquitoes should have one neuron, receptor, and glomerulus for smelling body odor and a separate scheme for carbon dioxide, Younger working with Margaret Herre - co-author of the study - found evidence of individual odor neurons with multiple different receptors.

“One major strategy for controlling mosquitoes is to attract them to traps to remove them from the biting population. If we could use this knowledge to understand how human odor is represented in the mosquito antennae and brain, we could develop blends that are more attractive to mosquitoes than we are. We could also develop repellants that target those receptors and neurons that detect a human odor,” said Younger.
