Pheromone traps in Virginia Beach captured a weekly total of 4 corn earworm moths at the Baker farm, 24 at the Henley farm, and 31 at the Hampton Roads AREC. Six were caught in the Eastern Shore AREC pheromone trap. Thanks to the following for their reports this week: Mary Beahm, Neil Clark, Mark Kraemer, Scott Reiter, Kelvin Wells, Watson Lawrence, Helene Doughty, Laura Maxey, Janet Spencer, David Moore, and the Tidewater AREC entomology crew.

Corn earworm pyrethroid vials tests show very high levels of survivorship
Corn earworm moth counts in local black light traps have increased from a few per night to 40-50 per night. These are not large numbers, but do indicate that moths are beginning to emerge from corn fields. Moths from corn are the second generation that migrates into soybean, cotton and peanut fields. We have run two batches of these second generation moths in our pyrethroid vial testing program with alarming results….55% (330 tested) and 59% (131 tested) survivorship for the July 26th and 27th samples (see the attached line graph). These are unprecedented levels for Virginia where in recent years, 40% survivorship was considered high. In a conversation with Dr. Rogers Leonard, a field crops entomologist at LSU, he confirmed that they are seeing even higher levels of survivorship in the Delta states and are dealing with extremely large corn earworm/tobacco budworm infestations in soybean. See more comments relating to soybean and cotton in the other July 28 advisories.

VT Tidewater AREC Pre-Harvest Field Tour–September 15, 2011
The Virginia Tech Tidewater Agricultural Research and Extension Center (AREC) will hold its pre-harvest field crops tour the morning of Thursday, September 15th. The tour will be held at the Center’s research farm at 1045 Hare Road in Suffolk. Specialists will display field research in progress and present valuable information for the 2011 harvest season and 2012 planting season. Important topics addressed will include cotton defoliation strategies; peanut variety and maturity assessment; cover crop establishment; variety evaluation in cotton, corn and grain sorghum; and disease and insect management in cotton, peanut, and soybean, including adaptation to the pending loss of Aldicarb (Temik®) nematicide-insecticide. Virginia private pesticide applicator certification credits will be available for participants. Lunch will be served after the tour and updates presented from USDA Farm Service Agency (FSA) and Natural Resource Conservation Service (NRCS).
Registration begins at 8:30 a.m. with the tour starting promptly at 9:00 a.m. Pre-registration by September 7th is highly encouraged by contacting Gail White at the Tidewater AREC (757-657-6450, ext. 430 or guwhite@vt.edu).
