Wing Drosophila Spring 2011 Update
This 4-page, full-color flyer discusses
the background of the SWD problem in Washington and provides information
on monitoring, identifying, and controlling the pest. Available in
English and Spanish.
Spotted Wing Drosophila in Grapes
Spotted wing drosophila (SWD) is now
present throughout Washington State and has demonstrated the
ability to lay eggs in both wine and juice grapes. Growers
grapes and juice
grapes should familiarize themselves
with this pest by reading the publications released Summer
2010 about monitoring, identifying, and controlling SWD. An August
2010 publication described initial research on the pest's
oviposition behavior on grapes in the laboratory.
Wing Drosophila: General
growers in Washington and Oregon are paying special attention
to spotted wing drosophila (SWD), a new and potentially devastating
pest that is moving north from California. There is a simple,
3-step process for identifying
SWD. The latest information can be found on the WSU
Extension SWD website, the WSU
Mount Vernon SWD Updates page, and the OSU
website devoted to this emerging pest. A bulletin
explaining monitoring, identification, and control of
released in July 2010 when the pest was confirmed in several
Eastern Washington locations. See also the November 2009 WSU
Press Release announcing collaborative efforts across the
state and the May 2010 Tri-City
Herald newspaper article about WSU and SWD. For further
information about SWD in western Washington, contact Lynell
Tanigoshi; in eastern Washington,
contact Doug Walsh.
Grape Virus and Vector Research
sure to visit the WSU Viticulture Extension Grape
Virology Website for background and emerging
information on virus diseases, including indentification and
management. For the latest information on

Bulletin addressing this topic.
Research at WSU Prosser
Barrier sprays of newer synthetic pyrethroids directed at the
base of grape vines were successfulin preventing cutworms from climbing
up and damaging buds. The cutworm responsible for bud damage is
the spotted cutworm, Amathes
In insecticide efficacy trials for grape mealybug control, several
new compounds showed effective control with delayed-dormant or in-season
application. In addition, chemigation treatment with Admire and
Platinum was effective in suppressing mealybugs.
Strawberry, Blueberry Research in western Washington
Fruit Pest Management Program at
Vernon research station is the home of the university's
small fruit pest management program. Their research and extension
is focused on new and cost effective integrated strategies in
support of the state's $100 million small fruit industry.
Research in western Washington
Much of the cranberry research and extension activities is being
carried out by the WSU
Long Beach Research Station. Programs at WSU Long Beach are
varied and multi-disciplinary. These include research in cranberry
weed control and physiology, cranberry best management practices,
integrated pest management, and cranberry pollination. Contact Kim
Patten for more information.
