Corn Earworms

Fresh silking corn should be protected now.

alert - corn earworm found in New Hampshire

Our network of sweet corn insect traps has detected a major corn earworm flight. Most of our traps are in Hillsborough and Merrimack Counties, so we have no data for the seacoast or Lakes region. On July 30 and 31 we found very high numbers of earworm moths in Litchfield, Hollis and Milford. We may find more. Fresh silking corn should be protected now.
