Spotted
Wing Drosophila Update
by Wei Yang, Oregon State University Berry Crops Extension Agent
With
funding support from the Oregon Blueberry Commission and ODA, OSU,
USDA, and Peerbolt Crop Management, I conducted a series of experiments
in blueberries during summer 2010 to develop the best IPM (integrated
pest management) practices for controlling spotted wing drosophila
(SWD). A statewide monitoring program began in late April and SWD
male and female fly populations were monitored using vinegar traps
in commercial blueberry fields.
By late July, SWD appeared in all the counties along the I-5 corridor,
indicating SWD was widespread in Oregon blueberry fields.
To determine the best treatment options, many chemical trials were
conducted in early, mid and late blueberry cultivars. Mass trapping,
organic insecticides and sanitation practices were evaluated for
controlling SWD in organic production systems. How blueberry ripeness
stages, fruit firmness, pH and Brix affect egg laying and developing
SWD were also studied in early, mid and late cultivars. After harvest,
SWD activity was monitored using ground traps and in fruits fallen
on the ground. How SWD overwinters in Oregon will be carefully investigated
in the next few seasons. The good news is that OSU along with WSU,
UC California and USDA-ARS was awarded a $5.7 million Specialty
Crop Research Initiative grant to combat this new pest. The research
results from many SWD experiments will be presented in various grower
meetings this winter.
Those
interested in hearing the latest SWD research and control measures
for the new growing season, with a focus on berry crops, may sign
up for free ($10 per person donation suggested) for a SWD Research
Update and Season Warm Up Workshop on April 21, 2011 from 1:00 –
4:00 p.m. at the North Willamette Research & Extension Center
in Aurora. You will learn the current recommended trap design and
usage, monitoring for adults and larvae, spray application timing
and chemical choices for control. Future planned research activities
will also be presented. Speakers for the event will include Amy
Dreves, Denny Bruck, Walton Vaughn, Lynell Tanigoshi and Jana Lee.
Pre-registration is required and space is limited, so sign up early.
