IF ORCHIDS can trick wasps to pollinate them through a chemical they produce that mimics the scent of their prey, the honey bee, can this type of research be used elsewhere? "Various species of Vespa are problems to beekeepers, because they plunder the hives," said researcher Manfred Ayasse of the University of Ulm in Germany, in discussing his published research (see above). "Besides this, their ravages of fruit crops make hornets a serious pest to man. Our results could be used to develop environmentally responsible traps for pest hornets." This is a photo of a Western yellowjacket (Vespula pensylvanica), a queen, drinking water in May of 2009 at the Harry H. Laidlaw Jr. Honey Bee Research Facility. (Photo by Kathy Keatley Garvey)
