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.

SWD Management in 2014

This year we’ve seen a very welcome decline in the region’s early season SWD population. However, since this insect first showed up here in 2009 we have always seen the populations build to economically damaging levels in the later part of the season on the west side. For me, the question isn’t if but when we’ll reach those levels again this year. We’re still learning about this insect. My general advice is: Don’t Take Chances. Don’t increase your late season risk by backing off the insecticide management programs (both conventional & organic) that have gotten us through the past four seasons. It isn’t worth it. As we gain confidence in our capacity to predict risk levels better we can begin adjusting management programs by seasonal indicators. We aren’t there yet. Stick with what has worked—the recommended spray program
