Corn earworm moth report for July 28, 2022

Corn earworm (=bollworm) moth captures have started to climb in local black light traps. Sara Rutherford (Greensville ANR Agent) reported a nightly average of 17.7 moths; Scott Reiter (Prince George ANR Agent) had 6.5 per night at Templeton and 10.3 at Disputanta; and we averaged 17.9 in Suffolk. Here is the Table. We have also started our corn earworm moth pyrethroid resistance monitoring program–this week we had 55% survival in vials containing 5 micrograms of the pyrethroid, cypermethrin (n=82 moths tested).
