SWD Update

Wednesday, August 17, 2016

We are continuing to monitor for SWD as we move through the harvest season.  The Annapolis valley and western Nova Scotia have had positive captures (low levels) in field borders and in hedge rows for the last couple of weeks.

Yesterday, we had our first positive capture in Central NS in a hedgerow.  We found 1 male fly, in one of our traps. The trap is not in a wild blueberry field.  This capture is expected based on what we have seen in previous years.  We expect to see sporadic, low level captures over the next couple of weeks. Historically, we have not seen SWD populations increase rapidly until we get into September, and based on what we are seeing, this is what we are expecting this year, for central and Northern NS.  Growers with later harvest fields should consider monitoring those later fields.

At this point, there is no reason to consider treating any field for SWD.
