honey dyed red

In the course of a study on mosquito movement at a zoo in Manhattan, Kansas, researchers discovered that local colonies of honey bees had foraged on a sugar bait for the mosquitoes that had been applied to foliage near the zoo. The bait had been dyed for the purpose of tracking mosquitoes that had fed on it, but the dye also showed up in much of the bees’ honey. Here, a frame from one of the zoo’s bee hives shows honey dyed red (black arrow). The bait in this case was nontoxic, but the discovery indicates a need for further study on attractive toxic sugar baits’ impacts on bees and other nontarget insects.
