State experts to release wasps to kill emerald ash borer beetles
DENVER -- It’s a unique plan to save tens of thousands of trees in Colorado and it involves a parasitic wasp -- 1,000 of them to be exact. The Colorado Department of Agriculture hopes the wasp will kill the emerald ash borer, a shiny green beetle that has invaded the state. “It’s pretty bad,” said John Kaltenbach, a biological control specialist for the Colorado Department of Agriculture. "It’s probably the worst pest Colorado has ever seen.”
