Free workshop to identify SWD

May 2nd, 2012 | Category: News

MOUNT VERNON – The WSU Extension will hold a free Spotted Wing Drosophila (SWD) identification workshop from 1 to 3 p.m. on Wednesday, May 23 at the WSU Mt. Vernon Research and Education Center. Dr. Spotted Wing Drosophila is a recently established pest of soft fruit throughout Washington State. During the workshop, Beverly Gerdeman will teach  techniques in identifying SWD using a hand lens and microscope and how to avoid misidentification of similar looking flies. Participants will have the opportunity to dissect infested fruit, observe all the life stages of SWD and practice a salt-disclosing technique to subsample fruit.  The Center is located at 16650 State Route 536 in Mount Vernon. To register, contact Colleen Burrows at or (360) 676-6736 ext 22.
