There are 2 blacklight traps monitored in
Wilson County in the Pender's Cross Rds and Buckhorn areas. These
locations have just begun to being monitored.
Please click here to
view the Wilson County information as well as all blacklight trap
monitorings in NC. Select a pest on the left hand side to view blacklight
numbers. Looking at blacklight traps from other areas is also a
good indication to the CEW moth flight. Check this site often as
most blacklight traps are updated on Monday, Wednesday and Friday.
Corn earworm moths find flowering crops attractive to lay eggs, such as
corn, peanuts, soybeans (R4-R7 are at the greatest risk when pods are
present), cotton and grain sorghum. One female moth has the
potential to lay 2,500 eggs. It takes about 3-4 days for an egg to
hatch and then several more days for caterpillar to grow. So
following a peak of CEW moths on the blacklight means you should be
scouting more intensely in about a week.
Please see the following article by
Dr. Dominic Reisig, NC State University Extension Entomologist, on CEW in
soybeans. There is an online calculator for
CEW thresholds in soybeans. Enter information such as soybean row
width, sampling method, price of soybeans per bushel, price of
insecticide plus application per acre and the calculator will generate
the CEW threshold.
