Washington Red Raspberry Commission Progress Report for 2012 Project Project No: Title: First Alert Scouting of SWD in Western WA Personnel: Colleen Burrows, Chris Benedict, and Harlan Gough, WSU Whatcom County Extension Reporting Period: January to November 2012 Accomplishments: In May, a workshop was held in Mt. Vernon on identification of Spotted Wing Drosophila, led by Dr. Beverly Gerdeman. This was well attended by growers interested in doing their own scouting. Participants learned and practiced identifying the key features of identifying SWD and how to determine differences between look-alike drosophila. Selected raspberry fields were scouted for Spotted Wing Drosophila using the clear cup trap with apple cider vinegar bait. The fields were located throughout Whatcom, Skagit, and Pierce Counties with 2-3 traps placed per field. 59 traps in total were monitored from early-June through late-July and the data was posted on the WSU Whatcom County Extension website as the data was collected, where growers could monitor what was happening near their fields. Growers participating in the study received weekly updates on SWD trap counts in their fields. SWD counts were low in most fields and traps throughout the trapping season. Starting in early July, a trap and bait comparison was set up at 2 locations – a field in Whatcom County and the Northwest Washington Research and Extension Center in Mount Vernon. The traps tested were clear cups, red cups, the commercial Contech trap, and the commercial CAPtiva trap. These traps all used apple cider vinegar as bait. One other treatment of the clear cup using a sugar yeast blend was also tested. Four replications for each were arranged in a randomized complete block design at each location. Results: In the SWD scouting program, levels of SWD caught in traps were low or zero in most locations throughout the fruit ripening season. Traps near native tree regions showed higher counts early on, but decreased once treatment began. The yeast-sugar mix attracted the most SWD of all trap/bait combinations. Some differences were seen between the trap types, but not enough replications were studied to have any statistical significance. Publications: Scouting data has been published on the WSU Whatcom County Extension website following each scouting trip. Project reports and data summary will be published on the WSU Whatcom County Extension website by the end of 2012. 011
2013 WASHINGTON RED RASPBERRY COMMISSION RESEARCH PROPOSAL New Project Proposal Proposed Duration: (1 year) Project Title: Trap and bait testing for SWD in Northwest Washington Raspberries PI Colleen Burrows, WSU Whatcom County Extension, Agriculture Special Projects Coordinator 1000 N. Forest St. Suite 201, Bellingham, WA, 98225. (360) 676-6736 cburrows@wsu.edu Co-PI Chris Benedict, WSU Whatcom County Extension Agriculture Extension Educator 1000 N. Forest St. Suite 201, Bellingham, WA, 98225. (360) 676-6736 chrisbenedict@wsu.edu Year Initiated 2013 Current Year 2013 Terminating Year 2014 Total Project Request: Year 1 $4,934 Year 2 $ Year 3 $ Other funding sources: Agency Name: Washington Blueberry Commission Amt. Requested: $4,934 will be requested for matching work in blueberries. Description: Spotted Wing Drosophila (SWD) is a significant direct pest of soft fruit, including red raspberries in Western Washington. In recent years, adult mating and subsequent female ovipositional flight has not begun until well into the raspberry harvest period, generally in late July, indicating a need to more fully understand flight patterns and timing for first treatment. This project will test various traps and trap baits for SWD from May through August and in different locations of the field to determine which combinations are more effective at different times of the year; this will allow for maximization of an on-farm scouting program to accurately determine when SWD will become an issue in a given field and, potentially, to monitor populations after treatment has occurred. Justification and Background: Spotted Wing Drosophila (SWD) is a direct pest of red raspberry and has been found in Western Washington soft fruit with later harvests especially impacted. Many growers feel that they have adequate management measures but need to more fully know when to expect SWD. In 2011 and 2012, WSU Whatcom County coordinated scouting in Northwest Washington so that growers could predict when SWD populations would increase in their fields. 012
