Spotted Wing Drosophila - how to monitor and what we can do...

Friday, May 31, 2013

Hi folks,

I hope everyone is enjoying this nice weather and I'm sure the vines will respond to it as well!  I thought I'd take a minute to give you all an update on Spotted Wing Drosophila - if you have not heard about it, here's your chance to learn more...

This pest is a new invasive species that has been found in North America since 2010 and here in NS since 2011.  It is primarily a pest of soft fruit (strawberries, raspberries, blueberries, cherries, grapes etc...) and is different from native fruit fly species in that the adult female will lay it's egg inside the ripening fruit instead of waiting to colonize it after it starts to break down from being over ripe. There has been a fairly extensive trapping program in most soft fruit species in NS over the past two years and swd was detected in some vineyards last season.  The cooler spring and cold winter this year may impact this pest however, we are advising growers to be aware of the pest and do some monitoring in your vineyards this year to see if this may become a problem. 

Please see the new factsheet on our website Monitoring for Spotted Wing Drosophila for details on this pest and how to monitor!   There are a number of insecticides that have received emergency use registrations for this pest and they will be posted on our website as they become available. To date, Malathion, Ripcord and Pyganic have received registrations for the 2013 growing season.  If you have any questions on this or any other pest, please do not hesitate to contact me! 

Stay tuned... we are working on our first Vineyard Walk for 2013 - details will be announced shortly!!!!!!!!  And on that note... if you are interested in hosting a vineyard walk sometime during the 2013 season at your vineyard, please let me know!
