The spotted wing drosophila will attack thin-skinned fruit such as raspberry, blackberry, blueberry, strawberry, cherry, plum, peach, nectarine, and sometimes grape. suzukii. The fly called spotted wing drosophila (SWD, Drosophila suzukii) is emerging as a global plant pest of significance. Oregon State University, University of Idaho and Washington State University. The flies are most prevalent in the lower, shaded parts of the plants. See: EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. our common “fruit flies”). University of Maine Cooperative Extension shows how to identify the damage caused by Spotted Wing Drosophila. A Pacific Northwest Extension Publication, PNW 507. This USDA National Institute of Food and Agriculture - Specialty Crop Research Initiative funded project represents a coordinated, comprehensive, region-wide investigation into the biology and management of Spotted Wing Drosophila on small and stone fruit for industry and non-commercial producers in Oregon, Washington, and California. Whilst sharing some natural viruses with its close relative D. melanogaster, D. suzukii also harbours a number of unique viruses specific to it alone.

Spotted wing drosophila. Many species of fruit flies are present in late summer; most normally infest overripe, fallen, decaying fruit, so are not crop-limiting pests. As the end of summer is approaching and fall bearing raspberry are getting ready for harvest, it is important to review the management strategies that should be implemented to manage the infamous spotted-wing drosophila (SWD; Figure 1). And unlike other fruit flies that target mostly rotting or fermenting fruit, SWD targets fruit right on the tree, laying their eggs in the young fruit and eventually turning it into a wormy mess. Oregon State University Spotted Wing Drosophila. [25] Farmers are advised to place these traps in a shaded area as soon as the first fruit is set and to not remove them until the end of harvest.

Many species of fruit flies are present in late summer; most normally infest overripe, fallen, decaying fruit, so are not crop-limiting pests. Since the spotted wing Drosophila (SWD), Drosophila suzukii, was first found in Michigan in 2010, it has become a serious pest of commercially-grown raspberries, blueberries, cherries and other fruit crops, resulting in the loss of well over 25 million dollars.This insect can also be a troublesome pest in home fruit plantings, especially for people who wish to keep pesticide use to minimal levels. That makes the SWD a menace to a wide variety … Genus species: Drosophila suzukii Simple traps can be made to monitor for this very important pest — research on SWD traps and baits has shown that the commercially available traps and lures by Scentry and Trece work as effectively as the home-made whole wheat dough trap. It infests ripening cherries throughout the state and ripening raspberry, blackberry, blueberry, and strawberry crops, especially in coastal areas. 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. [12] Larvae may leave the fruit, or remain inside it, to pupate. Introduction; Recognizing fruit damage; For more information; Introduction. Traps that use apple cider vinegar with a whole wheat dough bait have been successful for farmers to both capture and monitor D. Adult SWD are small, 1/16 to 1/8 in long (2‐3 mm) with red eyes and a light brown thorax and abdomen. It first appeared in North America in central California in August 2008,[4] then the Pacific Northwest in 2009,[11] and is now widespread throughout California's coastal counties,[12] western Oregon, western Washington,[4] and parts of British Columbia[13] and Florida.

[4] The fertilized female searches for ripe fruit, lands on the fruit, inserts its serrated ovipositor to pierce the skin and deposits a clutch of 1 to 3 eggs per insertion. Spotted wing drosophila adults can be blown by wind to nearby locations or transported to new regions via infested fruit. Spotted Wing Drosophila (Drosophila suzukii), SWD, is a recently introduced new species of fruit fly in the United States.It was first found on the west coast in 2008, but has rapidly colonized many fruit producing regions of the country. When first observed in a new region, D. suzukii has often been confused with the western cherry fruit fly (Rhagoletis indifferens) and was given the short-lasting name cherry vinegar fly. The spotted wing drosophila is an invasive fly that first arrived in the United States in 2008, Lahiri says, eventually making its way nationwide … including Drosophila melanogaster.

Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. Growers and researchers are working together to implement effective pest control strategies. acetamiprid-In field tests, this product has provided inconsistent control of SWD. If adult SWD are present on your farm, manage them aggressively. Our national team of biologists and social scientist has assembled with the goal of developing sustainable strategies to manage spotted wing drosophila (Drosophila suzukii), an invasive fly native to eastern Asia that damages soft skinned fruit crops, rendering them unmarketable. It made its way into New York by 2011. It became established in Hawaii during the 1980’s, and was first discovered in the continental United States in California in 2008.

D. suzukii, originally from southeast Asia, is becoming a major pest species in America and Europe, because it infests fruit early during the ripening stage, in contrast with other Drosophila species that infest only rotting fruit.
