Japanese beetle, Popillia japonica (Newman) adult counts based on degree days (DD10ºC) at the Chicago Botanic Garden (Glencoe, IL) from 1996 through 2002. Adult counts obtained using four Trece Catch Can Traps (Trece Incorporated, Adair, OK) located throughout the Chicago Botanic Garden. Traps were baited with Trece 3-Way Lure (Trece Incorporated, Adair, OK). Data not available for 1999.
