Nine sites reporting this week. European corn borer (ECB)-E was caught at Farmington and Seneca Castle. ECB-Z was caught at three sites, Batavia, Eden and Spencerport. Corn earworm (CEW) was caught in Eden and Spencerport with the Spencerport site high enough to begin a 6 day spray interval (see table at bottom of page). Fall armyworm (FAW) was caught at Eden, Kennedy and Randsomville.
Fields at the most advanced stage of development will be most attractive to egg-laying ECB moths. Larvae hatching from eggs laid now will feed in the whorl and be found later in the emerging tassel. Degree day accumulations, based on the nearest NEWA weather station, are given for each trapping site. Most sites are close to the accumulated degree days for first ECB spring flight and several are near the accumulated degree days for first eggs. ECB eggs require 100 degree days (base 50) from oviposition to hatch. Degree day calculations for many locations may be found on the NEWA web site.
