This is a seasonal scouting report giving growers in the Western New
York area information on the presence of sweet corn pests and recommendations
on scouting and thresholds. The report is written by
Abby Seaman, NYS IPM's Area Extension Educator
for Vegetables.
For 6/11/02
The ECB flight has taken a jump this week at most locations with the
warmer temperatures, and we're catching Z race moths at more sites.
One CEW caught at both Eden and Medina.
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. Demonstrations
have shown that insecticides applied before tassel emergence do not
improve control compared with fields that received only tassel emergence
applications. Information from North Carolina indicates that CEW
will lay eggs on the growing tips of small corn plants, and larvae will
feed on the whorl. The feeding sounds similar to FAW feeding, and any
CEW larvae can probably be targeted in a tassel emergence spray.
