Where is the Japanese Beetle in Colorado?

Each year CDA places Japanese beetle traps in nurseries, parks, golf courses, areas of agriculture and horticulture production to monitor for the pest and keep track of distribution.  CDAs primary purpose for trapping Japanese beetle is to support trade and certification of Japanese beetle free nursery stock and protect un-infested areas of Colorado and the Western U.S.  The map below contains Japanese beetle population data collected from 1990 – present day.
