Beetle Pheromone Lures Both Sexes BELTSVILLE, Md. Agricul tural Research Service scientists have discovered a pheromone produced by male Colorado pota to beetles but attractive to both sexes that may lead to new en vironmentally sound pest man agement methods to protect pota toes. The Colorado potato beetle is the potato crop’s most destruc tive pest, costing growers millions of dollars annually in crop losses and expenditures for synthetic pesticides.

The Colorado potato beetle rapidly develops resistance to synthetic pesticides, many of which are now being reevaluated by regulators. The pheromone, however, is a natural byproduct of the beetle’s metabolism, so the evolution of resistance to it is un likely. Using the pheromone as a natural chemical for luring and killing the beetles may one day lessen the amount of synthetic in secticides required for pest con trol. For 75 years, scientists in the United States, Canada and Eu- Case IH AgCo Fendt Tractors John Deere AgCo Fendt Tractors AgCo Fendt Tractors Blue Seal Fee rope have searched for scents that attract the Colorado potato beetle. The generally accepted view had been that a pheromone attractant would be found in fe males. Thus, the discovery of the attractant in males provides a new model for this beetle’s chem ical communication. Since 2000, Dickens has identi fied several scents based on chemicals in potato plants them selves. Those scents were made into the first experimental plant lures to prove effective in field tests. Under a cooperative research and development agreement with ARS, Trece, Inc., of Salinas, Calif., hopes to create prod ucts based on the newly dis covered attractants that will exploit the insects’ own com- munication system. New products based on the tech nology could include attracti cides, or bait lures, formulat ed with small amounts of killing agents. The scientists now will conduct more tests to de termine when and how prod- ucts using the pheromone based attractant will transfer successfully from lab to field.
