Now is definitely the time to be putting out traps. SCFS Members have already found SCFS in sour cherries, raspberries, tayberries, boysenberries, blackberries, and strawberries. Do you have SWD in your fruit? Here are some good photos of what damaged fruit can look like.
We still have traps for sale – 5 traps for $10. Please email Mark at SnohomishCFS@gmail.com if you are interested in purchasing some.
Our SWD Trap Type and Bait Longevity Research Project is in full swing now. Here are a few pictures from the journey so far.
SWD is a vinegar fly originally from Asia that appeared in Washington state in 2009. Because of a robust ovipositor (egg injection tube) the SWD lays eggs in healthy ripening fruit while they are still attached to the plant as well as overripe fruit. Infested fruits then began to deteriorate due to larvae activity as well as secondary fungal and bacterial infections. Life cycles are 8-15 days allowing for up to ten generations in one summer and they are able to overwinter in our climate. Females can lay 200-600 eggs in a lifetime.
Males are easily identifiable due to a black spot on their wings, red eyes, and two dark bands on their front legs. Females lack the dark spot but have a distinct, serrated ovipositor which is carried tucked under her abdomen.
Oregon State University and Washington State University are some of the leaders in the research regarding SWD in the United States.
SCFS applied for and received a grant to conduct research on trap design and bait longevity this summer. See our grant proposal here (SCFS2013FlyStudyWebInfo). If you are in the Snohomish County or interested in helping with this research, send us an email.
