Ron Hines, senior research specialist at the Dixon Springs Agricultural Center, is at it early again this year. Ron placed pheromone traps for armyworm and black cutworm adults at four sites on March 14. He placed two traps (bottomland and upland) at the Dixon Springs Ag Center in Pope County, one trap in Massac County, and one trap in Pulaski County. Ron checked the traps on March 18 and found one black cutworm moth each in the traps in Massac County and Pope County (upland). So black cutworms are beginning their migration northward. However, we won't begin predicting cutting dates until intense captures (nine or more moths captured in a 1- to 2-day period) occur.
A little later this season, Ron will place other insect traps in southern Illinois to monitor activities of corn earworms, European corn borers, fall armyworms, Japanese beetles, and southwestern corn borers. He will continue to provide commentary regarding these captures in "The Hines Report" on the IPM Web site (www.ipm.uiuc.edu). Begin watching there for weekly updates.--Kevin Steffey
