About Spotted Wing Drosophila and the SCRI SWD Project

Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. Known in Oregon and the Pacific Northwest since about 2009, this species now appears to be established in many fruit growing regions around the country. Growers and researchers are working together to implement effective pest control strategies.

NEW!

A free workshop from 9am-1pm, Thursday May 22, 2014 at the North Willamette Research and Extension Center, 15210 NE Miley Rd, Aurora, OR 97002.

Registration is limited to 50 people. Please register in advance by email with: heather.andrews@oregonstate.edu

This workshop aims to educate growers about  management of Spotted Wing Drosophila. Each topic will be followed by a short discussion to allow for feedback and the voicing of ideas.

  • Identify “hot” spots on your farm: When should you spray non-crop vegetation?
  • Predict spring activity and population increase: How to use a degree-day model.
  • Recognize risky situations: Why some crops are at greater risk of damage than others.
  • Recognize susceptible fruit types and stages: Fruits vary in their susceptibility.
  • Trap adults to confirm presence and activity: Best traps and baits; when - where - how to use traps.
  • Reduce SWD damage with cultural practices: Harvest promptly; the importance of pruning; mass trapping; ground mats.
  • Assess fruit for larval infestation: See how to extract larvae from fruit.
  • Reduce chemical applications: Border sprays and alternate row spraying; mistigation.
  • Clean up infested fruit: Why sanitation is important; how to optimize on-farm techniques.
  • Keep fruit cold: Impact of cold storage - recommended temperatures and times.

The primary funding for this collaborative Spotted Wing Drosophila project is provided by: USDA-NIFA SCRI Competitive Research Grant Number 2010-51181-21167
