Spotted-wing Drosophila Canadian Webinar Series - Highlights
Four webinars, each comprised of 4-6 presentations were held during winter 2016-17. The goal was to share Canadian research and extension activities related to Spotted-wing Drosophila (SWD) biology and management and provide a forum to discuss and identify next steps towards robust sustainable control solutions.
The webinar series was delivered by the national Spotted-wing Drosophila Technical Working Group.
Attendance over the four sessions totaled more than 340 participants from various sectors, including research, the provinces, extension, as well as pest management and farming industries.

- Berry crops, including raspberries, blueberries, and blackberries continue to be at high risk from SWD. Some stone fruit, particularly late season cherries and plums are at risk from SWD. Strawberries are at moderate to high risk. Generally early berries escape impact by SWD and mid to late fruit are at high risk.
- SWD can overwinter in Canada and survives in wild hosts. There are many wild fruit species that SWD utilizes, providing refuge and contributing to population buildup over the season.
- There is a need for more efficient monitoring systems, including predictive tools like degree day models and guidance on interpretation of the data collected (action thresholds). Though many traps and bait systems have been developed, none is particularly selective or efficient at detecting SWD in a timely way, and these traps generally are not competitive with ripening fruit in attracting the pest.
- Though progress has been made in pest management tools and approaches, continued work is needed on chemical control, cultural practices, biological control, other novel approaches and integration of tools.
- An on-line participant feedback survey on the webinars revealed that the webinars were generally viewed as an effective means of sharing information; over 90% of respondents said they learned something new and information was relevant to their situation.
- It is anticipated that the information shared at this series will support and encourage further studies on SWD biology and management. Some priorities for future action will be identified under the Pest Management Centre's Reduced Risk Strategy for Berry Insect Pests.
