A change-up in the bait and spacing of trees used to capture mountain pine beetle could help to reduce the pest’s destructive path across forests in Western Canada. Researchers at the University of Alberta (UofA) discovered they could catch more of the beetles by tweaking existing bait and altering the spacing of trees baited to catch them.  …While there are two types of chemicals that can be used in bait to attract beetles to a tree, only one type is typically used in bait. But Klutsch’s research doubled up, including both types of chemical in the bait.But Klutsch’s research doubled up, including both types of chemical in the bait. “We added both (chemicals) along with the mountain pine beetle pheromone, and that led to greater catches of mountain pine beetle,” Klutsch said.
