Three SWD (2 females and 1 male) were caught during the week ending on June 21, 2021 in Dutchess County. Four traps are set on the edge of a sweet cherry orchard with harvest underway, two red sticky cards and two jar traps. The insects were caught in the jar traps.
Because harvest is underway, it is difficult to impossible to apply insecticides at this point, given the need to observe the labeled pre-harvest interval (PHI). That said, because numbers are low, about 1.5 SWD on average, per trap, the crop may escape infestation and be harvested before significant, noticeable damage occurs. If sweet cherry varieties are picked at different times, spanning a two-week-long period, then judicious application of insecticides with appropriate PHI's to the later season varieties may prove beneficial, so as not to stretch the interval since the last spray much past 7 to 10 days. Review the insecticide quick guide for stone fruit for more information.
Best practice post-harvest is refrigeration or cold storage at around 34° F. Review other management tactics on the SWD Management page.
