Sustained trap catch is a milestone often used in IPM for timing management tactics against insect pests. Insect traps in the SWD monitoring network are checked once per week until adult SWD have been caught for two consecutive weeks at that location, indicating sustained trap catch.
On the blog, we post SWD first catch reports. Some of these reports may not prove to be first sustained trap catch because SWD adults are not caught the following week. This was the case this week for the traps in Suffolk, Onondaga, and Cayuga Counties. No SWD adults were caught at these locations this week, July 14 to 18, and in Suffolk County, no infested fruit was detected.
This indicates that SWD populations are still very low in NY. Cultural practices such as removing overripe berries from the planting, clean picking, dragging equipment across the ground to squash and break up dropped berries, etc., may provide some benefit, particularly in crops that are nearing the end of the harvest window, such as summer raspberries.
