Black Cutworm Moths Have Begun Their Arrival

Black cutworm trap cooperators have detected that moths are beginning their traverse to Indiana this past week. Though numbers are currently low, see Black Cutworm Pheromone Trap Report, we will expect more arrival with anticipated storms from the Southwest. Timing, and intensity, of moth captures allows us to begin tracking heat unit accumulations and anticipating larval development. A late-planting spring and numerous arriving moths, along with delayed weed/cover crop termination, could set the stage for significant field damage. Will it happen this year? I hope not. But, I sure am grateful to trappers from Posey to St. Joseph Counties that are watching and counting. Happy Scouting!
