WNY Sweet Corn Trap Network Report 9.22.14

Fifteen sites reporting this week. European corn borer (ECB)-E was caught at two sites while ECB-Z was caught at three sites this week. Eleven sites reported Corn earworm (CEW) with nine sites high enough to require a 6, 5, or 4 day spray schedule.  Thirteen sites reported Fall armyworm (FAW) and only one site caught western bean cutworm (WBC) this week.

I conducted a harvest evaluation today where I found over 10% damage due to WBC. This is still a fairly new pest in NY and economic damage has not been recorded. The larvae can be identified by the two dark bands located behind the head capsule.

Below or graphs of the flights for 2015 and 2014 for comparison. The biggest difference between the two years was the much lower CEW flight in 2015 as compared to 2014. WBC flight was on average greater this year (2015). The first generation flight of ECB-E was not as high this year as compared to 2014.
