Counties colored white do not have traps reporting to the map. Trap catch reports update to the map within an hour. The color scheme denotes the month of the first trap catch report for that County. Oneida County (colored gray) had SWD traps in one location where, in August, the crop was harvested, SWD had not been caught, and the traps were taken down. In Steuben County (colored gray), SWD was not caught in traps, but larvae were found in fruit at the trap location. By late August, most traps in the network were taken down because sustained trap catch had been attained.
