Spotted wing drosophila were detected for the first time (this year) in this week’s survey conducted by Deb Moreau. In total, 9 males and 2 females were captured in traps placed within raspberry and highbush blueberry crops and adjacent border vegetation. The majority (7 flies) were found in wild host plants on the edges of the crops being monitored.
I cannot advise as to whether management is warranted at your operation as only site specific trapping can provide this information. To review trapping techniques and identification characteristics of this pest please review the following factsheets
