Study reveals honey bees' olfactory changes from larvae to adulthood.

Researchers led by Gene Robinson have found that honey bee larvae temporarily lose their ability to detect odors due to reduced expression of a key olfactory gene. This phenomenon is linked to the social evolution of honey bees, as detailed in the Proceedings of the National Academy of Sciences. Honey bees exhibit a highly eusocial structure where reproduction is limited to a few individuals, while non-reproductive workers care for the young, with honey bees providing one of the highest levels of care.
