Small Fruit Farmers are Advised to Monitor for Spotted Wing Drosophila

March, 2014 - In 2013, Spotted Wing Drosophila (SWD) was captured in monitoring traps and very quickly became a devastating pest of berry crops in Missouri. In addition to small fruit crops, this invasive insect pest also attacks some stone fruits (cherry, nectarine, peach), high tunnel tomatoes, and wild hosts (including pokeweed, autumn olive, crabapple, nightshade, Amur honeysuckle, and wild grape). Raspberries, blackberries, blueberries, elderberries and grapes are at the greatest risk. If you grow any of these fruits, then for the 2014 growing season you are advised to monitor for this invasive pest. Integrated Pest Management (IPM) options to manage SWD in high tunnels include monitoring, sanitation, exclusion, and timely application of lower risk insecticide sprays. Research aimed at identifying additional management options will be conducted by the LU IPM Program. Free monitoring traps and yeast-based bait are available at no cost by contacting Mr. Jacob Wilson at or (573) 681- 5591. For further information on SWD identification go to LU IPM program website:
