A new study that explores the effect of smoke on honey bee (Apis mellifera) behavior finds that it reduces the instance of bees releasing a venom droplet in their signaling of danger to other bees, which researchers speculate may thereby reduce the amount of alarm pheromone released.
In the course of a study on mosquito movement, researchers discovered that local colonies of honey bees had foraged on a nontoxic sugar bait meant for the mosquitoes. The bait was dyed red to track mosquitoes that fed on it, but the dye also showed up in much of the bees' honey.
A review of existing research on floral resource competition between managed honey bees and wild bees shows gaps in our knowledge about such interactions and calls for further research to better inform decisions on honey bee management and pollinator protection.
Solitary bees face different—and less well-understood—challenges from pesticide exposure than their colony-dwelling honey bee cousins. A pair of entomologists encourage colleagues to dedicate more research to these important pollinators.
