Entomologist Juliana Rangel, Ph.D., and her research group at Texas A&M University College Station found that a widely used pesticide—the miticide amitraz—used to protect honey bees from mite infestation had an effect on mating among the queens. She is now continuing her studies of the effects of this and other pesticides on queen and drone honey bees. (Photo courtesy of Juliana Rangel, Ph.D.)
