Raef Parker reports lower trap catches of corn earworm this week compared with the previous week. Traps are averaging about 2-10 moths per night.

Heavy corn earworm activity in the Northern Neck of Virginia and summary of insecticide work in sweet corn
Based on pheromone moth traps monitored by Rafe Parker from Parker Farms, Oak Grove, Va, corn earworm moth activity has picked up significantly in the Northern Neck Region of Virginia. Counts jumped from less than 10 for past 2 weeks to about 100 moths this week. these moths will be flying to sweet corn, soybeans, cotton, green beans, and tomatoes among other crops. Be on the lookout for the eggs and small larvae of this pest, or begin the preventative spray programs. There are a wide range of effective insecticides for this pest. Sweet corn is probably the most difficult crop to achieve effective control of corn earworm because very few insecticides kill the eggs, eggs develop and hatch quickly in the summer heat, and larvae move down the silks and into ears where they are protected.

Early corn earworm activity in Virginia subsides
After some higher than usual corn earworm pest activity for the spring in Virginia, moth catch at traps has subsided. Raef Parker in the Northern Neck of Virginia is maintaining a couple corn earworm pheromone traps. A couple weeks ago he was catching several moths per night, but this week, the traps have gone silent, which is a good indication that new eggs of this pest are not being laid. Typically, corn earworm pest activity picks up dramatically in mid-July. So, hopefully, we’re in the clear for a little while anyway.

Early season corn earworm activity and control options in sweet corn
Over the past couple of weeks many areas of Virginia experienced some unusually high corn earworm moth activity. This early brief peak of moths was not typical, was likely not the result of migratory moths coming up from the southern U.S., but rather was the result of overwintering corn earworm pupae in Virginia and the fact that we had record high densities of this pest last summer. Nonetheless, this early blip in activity has pretty much run its course. However, if sweet corn was at a vulnerable state (tassel or later), there could be much more “worm” pressure on early sweet corn.
Based on 30 years of monitoring, the major flight of corn earworms will likely occur in mid-July in Virginia.
