FYI

Funding for the Spotted Wing Drosophila (SWD) scouting program that collects the data posted on this website comes from: the Oregon Department of Ag, the Washington the Red Raspberry, Washington Blueberry, and Washington Strawberry commissions, the USDA’s Northwest Center for Small Fruits Research, and the clients of Peerbolt Crop Management.

Some field data in both states comes from Peerbolt Crop Management client fields. Data also comes from individual growers and researchers. All data is gathered and reported by identifying fields/sites by the quadrant of the county where they are located.

All grower contact information and exact field/site locations are confidential.

General Comments from Peerbolt Crop Management

  • Trap counts continue to indicate a much higher winter survival rate than previous years.
  • With a few exceptions, most locations are not showing any increase in numbers over the previous weeks. The most likely explanation for this is that we’re still catching primarily the overwintering generation. The first 2012 hatch hasn’t yet shown up.
  • A couple of locations are showing a different pattern:
    • OSU entomologist Amy Dreves is catching high numbers in wild habitat sites in Linn County..
    • One of our client's cherry orchard traps (not included in the public data below) had a single trap count this week of 29 males/ 104 females. We don’t have a good explanation for this anomaly but it is cause for concern & will be watched closely to see if it’s an indication of a possible early season threat to nearby strawberries & caneberries.
  • With no ripening fruit in the fields there is no reason to apply any insecticides at this time.
