JÃƒÂ¼rgen Tautz and Michael Rostas of the University of WÃƒÂ¼rzberg in Germany conducted a simple experiment with pepper plants and beet armyworm caterpillars in two enclosed tents. A hive was connected to one of the tents, and honeybees flew around on their way to two sugar-solution feeders inside the tent.
After about two weeks, the researchers measured the amount of plant foliage eaten by the caterpillars. In the tent with the bees, they discovered, about 60 percent to 70 percent less foliage was consumed compared with the other tent.
