Insect Observations/Trap Data

Spring insect activity is off to a slow start, but is expected to pick up with the recent warming trend. Piatt, Madison, Montgomery, and Sangamon counties all recorded significant moth flights this week. Projected potential cutting dates are identified in the map below. Remember, these dates are just estimates, scouting should occur before and after the potential cutting dates.

True armyworm numbers have been very low. Armyworm traps are just getting going, so reports for this week are broken down into a general area of the state.
