Pest Survey Program cooperators across the state maintain black light traps to monitor moth flights as an early warning of potential pest problems. Insect counts reported each week can alert growers to the emergence, abundance, and seasonal occurrence of a variety of nocturnal agricultural pests. The results are presented below and will be updated weekly through August.
