The economic impact of D. suzukii on fruit crops is negative and significantly affects a wide variety of summer fruit in the United States including cherries, blueberries, grapes, nectarines, pears, plums, pluots, peaches, raspberries, and strawberries. After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. “Spotted wing drosophila is by far the fastest spreading pest I’ve ever seen,” Beers said. The newest pest arrival is the Spotted Wing Drosophila (SWD), a tiny vinegar fly with the potential to damage many fruit crops. Timing of the sprays is important to effectively controlling it. There are black stripes down its abdomen. The adult males have a single black spot on the tip of each wing, but the females lack this distinctive marking, making it difficult to identify this insect. [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. See: EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. Berry growers should set out traps to monitor SWD populations in their fields. Oregon State University Male Drosophila suzukii, note the dark spots near his wing tips, Female Drosophila suzukii, her wings are without spots, Electron microscope image of an ovipositor of a female Drosophila suzukii, Cherry with oviposition scars of Drosophila suzukii, Kanzawa, T. 1939 Report. 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. The adult males have a single black spot on the tip of each wing, but the females lack this distinctive marking, making it difficult to identify this insect. To enable basic and applied research of this important pest, we sequenced the D. suzukii ge … Damage: Spotted Wing Drosophila in Ontario Table of Contents. Adults: Florida is home to at least 27 addiional Drosophila spp. Introduction; Recognizing fruit damage; For more information; Introduction. It is a fruit-killing machine. There are a number of reasons that control of any insect may be poor. [6] The larvae are small, white, and cylindrical reaching 3.5 millimetres (9⁄64 in) in length.[4]. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. [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. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. Kanzawa. Larvae are small, legless, up to 1/8 inch long, cream colored and … The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. We are slowly learning to live with it in Wisconsin since its first detection in 2010. Traps that use apple cider vinegar with a whole wheat dough bait have been successful for farmers to both capture and monitor D. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). Genus species: Drosophila suzukii Growers: Talk to your local CCE agent about monitoring SWD. Spotted wing drosophila (SWD), Drosophila suzukii(Matsumura), is an exotic pest of Asian origin. [5], Like other members of the Drosophilidae, D. suzukii is small, approximately 2 to 3.5 millimetres (5⁄64 to 9⁄64 in) in length and 5 to 6.5 millimetres (13⁄64 to 1⁄4 in) in wingspan [3] and looks like its fruit and vinegar fly relatives. College of Agricultural Sciences Steck GJ, Dixon W, Dean D (2009) Spotted Wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a fruit pest new to North America. The larvae hatch and grow in the fruit, destroying the fruit's commercial value. Biological control of the Spotted wing Drosophila - Drosophila suzukii. University of Maine Cooperative Extension shows how to identify the damage caused by Spotted Wing Drosophila. SWD are very similar in size, shape and appearance to other vinegar flies (i.e. It can directly infest the fruit of many plants, but is most attracted to raspberries, blackberries, blueberries, and other late-season, soft-flesh fruits — cultivated and wild. 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). kaolin clay (Surround at Home)-Repels some insect pests when applied as a spray to leaves, stems, and fruit. 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. Spotted wing drosophila (SWD) is a fruit fly that's on the move. Spotted wing drosophila. It attacks a range of soft skinned fruit and reduces crop yield and quality through direct feeding damage and secondary infection of the fruit. Drosophila suzukii. 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. Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. This is not the case with SWD. Spotted wing drosophila (SWD), Drosophila suzukii, is a fruit fly first found in 2008 damaging fruit in many California counties. In efficacy rankings, Delegate® WG insecticide has performed well in the battle against 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. [3], D. suzukii is a fruit crop pest and is a serious economic threat to soft summer fruit; i.e., cherries, blueberries, raspberries, blackberries, peaches, nectarines, apricots, grapes, and others. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. [44][45][46] The yeast species found to be most frequently associated with D. suzukii were Hanseniaspora uvarum, Metschnikowia pulcherrima, Pichia terricola, and P. Spotted Wing Drosophila. Spotted wing drosophila is a temperate fruit fly, native to Southeast Asia; preferring temperatures of 20-30 o C. It is known to infest thin-skinned fruit. our common “fruit flies”). Strik B (2005) Growing Kiwifruit. Many species of fruit flies are present in late summer; most normally infest overripe, fallen, decaying fruit, so are not crop-limiting pests. Spotted wing drosophila continue to plague raspberry, blackberry, blueberry, and grape growers. Spotted Wing Drosophila Larvae in Blueberry; photo by David Handley. Spotted wing drosophila adults can be blown by wind to nearby locations or transported to new regions via infested fruit. Biology Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is an exotic pest of Asian origin. The female even has a special egg-laying organ that is serrated like a saw, so she can lay her eggs inside ripening fruit. [39][40] Likely also ground beetles (Carabidae),[39] crickets,[39] green lacewings' larvae,[39] rove beetles (Staphylinidae) especially Dalotia coriaria,[39] birds,[39][41] and mammals.[39][41]. (Accessed November 2009). The spotted wing drosophila is an invasive pest from Asia, first discovered in California in 2008. [21] As D. suzukii continues to spread, most of the states will most likely observe it. “Females” means that they are vinegar flies without spots on the wings and assumed to be spotted wing drosophila (SWD), while males were readily identifiable with spots on the wings. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. With as many as 13 generations per season, and the ability for the female to lay up to 300 eggs each, the potential population size of D. suzukii is huge. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. Fruit flies (also called vinegar flies) are often associated with damaged, overripe, or rotting fruits and vegetables. [3] Generations hatched early in the year have shorter lifespans than generations hatched after September. [29] Sprays should be in place prior to egg laying and the coverage needs to be thorough because adults often hide in dense portion of the canopy. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. Spotted wing drosophila (SWD) is a member of the “small fruit fly” or “vinegar fly” genus Drosophila. (Enterobacteriaceae). Damage was first noticed in North America in the western states of California, Oregon, and Washington in 2008; yield loss estimates from that year vary widely, with negligible loss in some areas to 80% loss in others depending on location and crop. Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/) is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. 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. To prevent resistance to certain sprays, farmers must rotate among different insecticides. It became established in Hawaii during the 1980’s, and was first discovered in the continental United States in California in 2008. 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. Adults emerge from overwintering when temperatures reach approximately 10 °C (50 °F) (and 268 degree days). kluyveri. The larvae grow inside the fruit. Depending on the variety of soft fruit and laws in different states and countries, there are many types of organic and conventional sprays that are effective. [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. [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. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. 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. The adults are small (2-3 mm) flies with red eyes and a pale brown thorax and abdomen with black stripes on the abdomen, see Figure 1. Spotted Wing Drosophila: What we learned in 2014 and outlook into the 2015 field season . This method is effective from removing D. suzukii from gardens and small areas but is difficult for farmers with larger operations to do this. In Minnesota, SWD primarily attacks raspberries, blackberries (and other cane berries), blueberries, strawberries and wine grapes. EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. The spotted wing drosophila (SWD) is a fruit fly that is a 1/16 to 1/8 inch long with red eyes and a yellow-brown thorax and abdomen. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. Spotted wing drosophila is a small vinegar fly from East Asia that lays its eggs in softer, thin-skinned fruits, such as berries. The Spotted Wing Drosophila (SWD) is a vinegar fly of East Asian origin that can cause damage to many fruit crops. [7] The cherry fruit fly is significantly larger than D. suzukii (up to 5 millimetres (13⁄64 in)) and has a pattern of dark bands on its wings instead of the telltale spot of D. suzukii. Native to Asia, SWD is currently found in most of the primary fruit growing regions of the U.S. OMRI-listed for organic use. It was discovered in western Washington, Oregon and British Columbia in 2009, and in eastern Washington in June of 2010. Unlike most other vinegar flies it can damage otherwise unblemished soft and stone fruit including strawberries, raspberries, blackberries, currants, blueberries, grapes, cherries and plums. Most types of sprays need to be applied each week, at a minimum. We expect populations to increase in the coming weeks as more food (fruit) becomes available for the flies, especially if conditions remain warm and humid. It is also important to note that males of D. suzukii become sterile at 30 °C (86 °F) and population size may be limited in regions that reach that temperature. 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. Spotted wing Drosophila-related yield loss estimates have been applied to raspberry production estimates to quantify the value of these losses in California for nonorganic (Goodhue et al. Two- to three-millimeters long, the spotted wing drosophila fly first drew attention in 2008 in California. Spotted Wing Drosophila (SWD) is an invasive species of fruit fly that lays its eggs in thin-skinned fruits, such as blueberries, strawberries, raspberries and blackberries. It was first detected in the North Central region of the US in Michigan in 2010, and has spread rapidly. [12] Larvae may leave the fruit, or remain inside it, to pupate. If adult SWD are present on your farm, manage them aggressively. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. Look for fruit flies hovering around fruit and symptoms of premature fruit decay. If you fail to do so, you could face a $400 fine. Wasps native to the Northwest aren’t much of a threat to SWD. The fly called spotted wing drosophila (SWD, Drosophila suzukii) is emerging as a global plant pest of significance. [27], Farmers have the option of both conventional and organic sprays [28] to control D. suzukii. Due to its rapid reproductive rate and their ability to use over 100+ fruits for reproduction makes management of … Spotted wing drosophila. insidiosus. [17] In Fall 2010 the fly was also discovered in Michigan[18] and Wisconsin. Economic impacts are significant; losses from large scale infestation (20% loss) across the US alone could equate to farm gate impacts > $500M. Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. Adult flies are smaller than 4mm, colored light brown with red eyes. [30], Earwigs,[39] damsel bugs,[39] spiders,[39] ants,[39] and Orius ("minute pirate bugs")[39] especially O. There are black stripes down its abdomen. Although monitoring traps are used for early D. suzukii adult detection to time the start … The traps should be checked once a week and farmers should look for the spot on the wing of the males to determine if D. suzukii is present. Introduction. 2011) and organic raspberries (Farnsworth et al. [3] Research shows that many of the males and most of the females of the late-hatching generations overwinter in captivity—some living as long as 300 days. Photo by John Davis. The spotted wing drosophila is an invasive fly that first arrived in the United States in 2008, Lahiri says, eventually making its way nationwide … Oregon State University, University of Idaho and Washington State University. [2], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura, it was observed in Japan as early as 1916 by T. Generally, soft-skinned fruit become vulnerable to attack as they begin to soften and tur… Drosophila suzukii, like all insects, is host to a variety of microorganisms. Corvallis, Oregon 97331. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. The spotted wing Drosophila (SWD) is NOT that kind of fruit fly. Some of these could easily be confused with Drosophila suzukiidue to their spotted wings. Whilst sharing some natural viruses with its close relative D. melanogaster, D. suzukii also harbours a number of unique viruses specific to it alone. It is particularly damaging to late fruiting plantings of raspberries, blackberries, and strawberries. Spotted wing drosophilas are a global pest. Spotted Wing Drosophila. [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. Attacks a range of soft skinned fruit species; Egg deposition and larval feeding can occur in maturing, firm fruit; Small (2-3 mm in length) flies with yellow-brown colouring, dark bands on the abdomens and red eyes; The flies are most prevalent in the lower, shaded parts of the plants. A field study was conducted in 2013 to evaluate various baits for monitoring spotted wing drosophila. Spotted wing drosophila is a temperate fruit fly, native to Southeast Asia; preferring temperatures of 20-30 o C. It is known to infest thin-skinned fruit. This small insect has been in Hawaii since the 1980s, was detected in California in 2008, spread through the West Coast in 2009, and was detected in Florida, Utah, the Carolinas, Wisconsin and Michigan for the first time in 2010. Spotted-wing drosophila is a small fly that develops within many kinds of fruits. 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. Spotted wing drosophila (SWD) is a vinegar (fruit) fly that was first reported in Britain in 2012. Today, it has spread throughout most of the continental US. [42] This fly is also infected with a variety of viruses in the wild. A female may lay as many as 300 eggs during its lifespan. Adult SWD are small, 1/16 to 1/8 in long (2‐3 mm) with red eyes and a light brown thorax and abdomen. Western cherry fruit fly adults are much larger (5 mm) than the spotted-wing drosophila adults and have a dark banding pattern on their wings. It made its way into New York by 2011. Spotted wing drosophila is native to Southeast Asia, preferring temperatures of 20-30 °C. In Washington state, D. suzukii has been observed in association with two exotic and well-established species of blackberry, Rubus armeniacus (= Rubus discolor) and Rubus laciniatus (the Himalayan and Evergreen Blackberries, respectively.). 2009, http://extension.oregonstate.edu/news/story.php?S_No=729&storyType=news, http://www.ipm.ucdavis.edu/EXOTIC/drosophila.html, "Stop The Invasion - Spotted Wing Drosophila", http://www.agf.gov.bc.ca/cropprot/swd.htm, http://ncsmallfruitsipm.blogspot.com/p/spotted-wing-drosophila.html, http://extension.usu.edu/files/publications/publication/ENT-140-10.pdf, "Spotted Wing Drosophila IPM Working Group", "Spotted Wing Drosophila | Minnesota Department of Agriculture", http://www.eppo.org/QUARANTINE/Alert_List/insects/drosophila_suzukii.htm, "USDA Awards $6.7 Million To Stifle Spotted Wing Drosophila", "Spotted wing drosophila in home gardens", "Spotted Wing Drosophila Management Guidelines--UC IPM", "New guide to organic management of spotted wing Drosophila released", "Spotted Wing Drosophila Management | Entomology", "ASIAN GIANT HORNET STAKEHOLDER UPDATE #17 – DECEMBER 9, 2020", Washington State Department of Agriculture, "Catching hope: Possible ally in fight against harmful fruit fly discovered in Asian giant hornet trap", "Associations of Yeasts with Spotted-Wing Drosophila (Drosophila suzukii; Diptera: Drosophilidae) in Cherries and Raspberries", "Preliminary Screening of Potential Control Products against, Oregon State University horticulture site, Michigan State University Spotted Wing Drosophila site, Species Profile - Spotted Wing Drosophila (, United States National Agricultural Library, "EMERGING PEST: Spotted-Wing Drosophila-A Berry and Stone Fruit Pest". “Spotted wing drosophila have small, white legless larvae with no apparent head, and damaged fruit often feels soft and leaks juice,” Hamby says. Management-chemical control: HOME USE.

Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. A spotted wing drosophila are able to lay its eggs in healthy fruit that is still ripening, as opposed to other vinegar flies that only attack rotting fruit. Spotted wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly native to Southeast Asia. The traps used were all of the clear “deli cup” design. suzukii. Only adults overwinter successfully in the research conducted thus far. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. [8][9], D. suzukii has a slow rate of evolution due to its lower number of generations per year, because it enters winter diapause. That makes the SWD a menace to a wide variety … Unlike most other vinegar flies it can damage otherwise unblemished soft and stone fruit including strawberries, raspberries, blackberries, currants, blueberries, grapes, cherries and plums. The most distinguishable trait of the adult is that the males have a black spot near the tip of each wing. I have had some reports of poor control. The Alachua Grower (online) Profaizer D, Angeli G, Trainotti D, Marchel L, Zadra E, Sofia M, Ioriatti C, 2012. The oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. Aggressive management entails: 1. 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. Detections were made for the first time in Utah and Michigan in late summer/fall of 2010. This small insect has been in Hawaii since the 1980s, was detected in California in 2008, spread through the West Coast in 2009, and was detected in Florida, Utah, the Carolinas, Wisconsin and Michigan for the first time in 2010. For questions or feedback about our college or website, please Contact Us. [47] Although certain fungal pathogens have been shown to experimentally infect D. suzukii,[48][49][50] the wild fungal infections of D. suzukii remain to be explored comprehensively. The invasive fruit fly spotted-wing drosophila (Drosophila suzukii) causes extensive damage to cherry and berry crops, and effective monitoring is vital to control efforts.A new study in Michigan found that spotted-wing drosophila consistently prefer red, glue-covered monitoring traps made of rectangles of plastic or spheres of plastic compared to the most commonly used clear deli … The intestinal bacterial communities of adult and larval D. suzukii collected in its invasive range (USA), were found to be simple and mostly dominated by Tatumella spp. Drosophila suzukii Matsumura (spotted wing drosophila) has recently become a serious pest of a wide variety of fruit crops in the United States as well as in Europe, leading to substantial yearly crop losses. The spotted wing drosophila (SWD) is a fruit fly orginally from Asia, was found in Hawaii in the 1980s, in California in 2008, in Michigan in 2010 and in Maine in 2012. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. First detected in California in 2008, it has currently been detected in at least 41 states in the United States, and into Canada, Mexico, and many European countries. For pest description, crop damage, biology, life history, sampling and cultural management. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. [12] The $500 million actual loss due to pest damage in 2008—the first year D. suzukii was observed in California—is an indication of the potential damage the pest can cause upon introduction to a new location. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. In choice test bioassays, a synthetic lure containing the EAG-active blend in mineral oil attracted ~3 times more spotted wing drosophila than control (mineral oil alone) lures. Spotted Wing Drosophila, Drosophila suzukii (Matsumura) a new fruit pest of concern especially for strawberry, blackberry and blueberry growers. [4] The fly has been observed reproducing on many other species of soft-skinned wild fruit, however, research is still ongoing to determine the quality of individual species as reproductive hosts. The spotted wing drosophila (SWD) is a fruit fly that is a 1/16 to 1/8 inch long with red eyes and a yellow-brown thorax and abdomen. [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota in 2012. In other temperate climates, the spotted wing drosophila overwinters as an adult in protected areas, … This summer the SWD was captured … There are different types of traps, both commercial and home-made, that are effective in monitoring it. The spotted wing Drosophila (SWD) is a vinegar or fruit fly of East Asian origin. 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. They were detected in California in 2008, in Oregon and Washington the following year, in New England in … The antennae are short and stubby … 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 pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. acetamiprid-In field tests, this product has provided inconsistent control of SWD. 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. The most distinguishable trait of the adult is that the males have a black spot towards the tip of each wing. What makes the SWD different is that the female has an enlarged, serrated ovipositor (egg layer) that enables her to lay eggs under the skin of ripening fruits that are otherwise free of damage. Since D. suzukii is more active in the morning and evening those are the best times to control it. Therefore, expert examination by a specialist is needed for positive identification and confirmation (Steck et al. The spotted wing drosophila (Drosophila suzukii) is a fruit fly which originated in Japan and has spread across the world, first to the USA, then mainland Europe, before first being detected in the United Kingdom in 2012 at NIAB EMR in Kent. Management-chemical control: HOME USE. “We see good to excellent control with Delegate,” Hamby says. A novel control strategy could be in store for spotted wing drosophila, an invasive vinegar fly species from Asia that attacks more than 100 fruit crops, including blueberry, cherry, blackberry, and grape.
