Doctoral candidate Evan Palmer-Young and his advisor, evolutionary ecologist Lynn Adler, had reported in 2015 that a common parasitic infection of bumble bees was reduced when the bees fed on anabasine in sugar water. Anabasine is a natural alkaloid, nicotine-like chemical found in plant nectar. The researchers had hoped their finding was evidence that bees may use “nature’s medicine cabinet” to rid themselves of the intestinal parasite Crithidia bombi, which can decrease the survival of queen bees over the winter and hamper the success of young colonies in the spring.
