Corn earworm update for August 12, 2021

Corn earworm (=bollworm) moth catches continued to increase this week in our black light traps. The average number of moths caught per night was: Greensville = 10; Prince George-Templeton = 26 (Scott Reiter reported this trap is next to some early April-planted corn that the shucks are starting to dry down on); Prince George-Disputanta = 6; Southampton = 10; Suffolk = 27. Here is the Table. We found bollworm eggs in cotton in Greensville and Suffolk this week. The 2021 season average in our adult cypermethrin vial tests is 25% survival (562 moths tested).
