Alternative Strategy
Douglas-fir beetle repellent uses MCH – a naturally occurring anti-aggregation pheromone of the Douglas-fir beetle to protect living trees from attack by spruce and Douglas-fir beetles. It is also used to prevent the build-up of populations on logs, stumps, and fallen trees. MCH sends a message that the tree is full and that beetles should look elsewhere for a suitable host.Beetles and other insects communicate using pheromones. MCH replicates the beetle pheromone that tells other beetles the tree is full and that the food supply is insufficient for additional beetles. Arriving beetles receive the 'message' that they should look elsewhere for a suitable host.
