Pheromone traps have been established at sites throughout Wisconsin to monitor early-season flights of true armyworm moths. Counts from the trapping survey provide data on the timing of local moth flights and may be useful for planning field scouting activities. The results of the survey are presented below and will be updated weekly through mid-June.
