First Captures of Armyworm and Black Cutworm Moths Already
Ron Hines, senior research specialist at the Dixon Springs Agricultural Center, began his "trap lines" in early March. He has established insect-specific traps at six sites in southern Illinois countiesFayette, Jefferson, Massac, Pope, Pulaski, and St. Clair. You can read the details for yourselves at The Hines Report.
The first armyworm moth was captured in a pheromone trap on March 8 in Pope County, and three more armyworm moths have been captured since. The first and only black cutworm moth to date was captured in a pheromone trap in St. Clair County during the week ending March 20. You can track the development (by accumulation of degree-days) of these two early-season pests at www.ipm.uiuc.edu/degreedays. Click on "Degree-Day Calculator" in the upper-right corner of the page to begin the process. We will be making some changes to the degree-day/insect Web site in the near future, so stay tuned for developments.--Kevin Steffey
