Cooperative Extension: Maine Wild Blueberries

SWD trap captures in Washington County remained steady and similar to last week. At the University of Maine Blueberry Hill Farm, we continue to capture anywhere from one to thirty flies per trap; and the proportion of fruit that has SWD larvae appears to be very low (less than 1%) as we still have not […]

SWD trap captures continue to build throughout the state.  At the University of Maine Blueberry Hill Farm, we are now catching 10-30 flies/trap.  Traps in other areas Downeast are now capturing 30+ flies/trap.  These SWD continue to be mostly females; however, males appear to be making up a larger percentage than in previous weeks.  The […]

This summer appears to be a bit different than last year, the first year that we experienced SWD. It does appear that SWD is starting to build, evidence being multiple captures of two to seven flies/trap with a few males being captured. However, the buildup appears to be slow and there are still several fields […]

Trap captures of spotted wing drosophila continue to occur throughout the state BUT appear to have jumped up a bit. There are still some fields that have not had trap captures and many have had just the one or two SWD. However, late last week in southern Maine, trap captures jumped quickly with one small […]

As of last week, trap captures of spotted wing drosophila continue to occur throughout the state. There have only been a few fields at this point where multiple flies are being caught. Most fields either have had NO trap captures yet OR just one or two SWD. We have identified SWD larvae in fresh fruit […]

Trap captures of spotted wing drosophila continue to occur throughout the state. All blueberry growing regions have reports of SWD males and many fields have experienced multiple captures, indicating that reproduction is occurring and fruit infestation is taking place. But, let me be clear NOT ALL fields have captured SWD yet. On the other hand, […]

More SWD has been captured in the Downeast growing area on the blueberry barrens. Male SWD was caught and confirmed in a few locations. At the University of Maine, Blueberry Hill Farm SWD have been caught in more locations throughout the fields there. So far our fruit sampling (several fields sampled yesterday) has not revealed […]

More SWD has been captured in the coastal growing area. Nine flies were captured this past week in a Warren field and continued single SWD detections have been found in Union and Lincolnville. However, despite the number of fields where this pest has been captured in traps there are still several fields in this area […]

Dave Yarborough and Frank Drummond will be sending out SWD updates one to two times a week over the growing season. Frank and Judy Collins will be monitoring 18 field sites from Stockton Springs up to Jonesboro. Dr. Jim Dill and Dr. Dave Handley (UMaine Cooperative Extension) are monitoring traps in mid-coast to southern Maine […]
