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. Spotted wing drosophila (SWD), Drosophila suzukii(Matsumura), is an exotic pest of Asian origin. [17] In Fall 2010 the fly was also discovered in Michigan[18] and Wisconsin. 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. 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. “We see good to excellent control with Delegate,” Hamby says. [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. Kanzawa. Spotted wing drosophila (SWD) is a fruit fly that's on the move. 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. Spotted wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly native to Southeast Asia. Fruit flies (also called vinegar flies) are often associated with damaged, overripe, or rotting fruits and vegetables. 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. The Alachua Grower (online) Profaizer D, Angeli G, Trainotti D, Marchel L, Zadra E, Sofia M, Ioriatti C, 2012. 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. For pest description, crop damage, biology, life history, sampling and cultural management. If you fail to do so, you could face a $400 fine. Spotted Wing Drosophila: What we learned in 2014 and outlook into the 2015 field season . Spotted wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly native to Southeast Asia. Generally, soft-skinned fruit become vulnerable to attack as they begin to soften and tur… [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. Adult flies are smaller than 4mm, colored light brown with red eyes. [27], Farmers have the option of both conventional and organic sprays [28] to control D. suzukii. 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. Steck GJ, Dixon W, Dean D (2009) Spotted Wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a fruit pest new to North America. Spotted wing drosophila. . Since D. suzukii is more active in the morning and evening those are the best times to control it. 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. [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. Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. Economic impacts are significant; losses from large scale infestation (20% loss) across the US alone could equate to farm gate impacts > $500M. 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. 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. Disseminating the most current scientific knowledge of Spotted Wing Drosophila fruit fly biology, management, and effects on Pacific Northwest berry crops. Some of these could easily be confused with Drosophila suzukiidue to their spotted wings. [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]. 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. Growers and researchers are working together to implement effective pest control strategies. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. Management-chemical control: HOME USE. [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. It is particularly damaging to late fruiting plantings of raspberries, blackberries, and strawberries. Drosophila suzukii. To prevent resistance to certain sprays, farmers must rotate among different insecticides. Due to its rapid reproductive rate and their ability to use over 100+ fruits for reproduction makes management of … The most distinguishable trait of the adult is that the males have a black spot near the tip of each wing. The antennae are short and stubby … OMRI-listed for organic use. The Spotted Wing Drosophila (SWD) is a vinegar fly of East Asian origin that can cause damage to many fruit crops. In other temperate climates, the spotted wing drosophila overwinters as an adult in protected areas, … Economic losses have now been reported across North America and in Europe as the fly has spread to new areas. 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. [21] As D. suzukii continues to spread, most of the states will most likely observe it. Damage: Spotted Wing Drosophila in Ontario Table of Contents. Translated from Japanese by Shinji Kawaii. [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. kluyveri. 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. [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. There are black stripes down its abdomen. Unlike most other vinegar flies it can damage otherwise unblemished soft and stone fruit including strawberries, raspberries, blackberries, currants, blueberries, grapes, cherries and plums. [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. “Spotted wing drosophila is by far the fastest spreading pest I’ve ever seen,” Beers said. EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. It is now widespread in Coastal and Interior fruit growing areas of B.C. The newest pest arrival is the Spotted Wing Drosophila (SWD), a tiny vinegar fly with the potential to damage many fruit crops. The larvae hatch and grow in the fruit, destroying the fruit's commercial value.

This summer the SWD was captured … I have had some reports of poor control. Adults are small (2–3 mm) flies with red eyes, a pale brown thorax, and abdomen with black stripes. Spotted wing drosophila (SWD), Drosophila suzukii, is a fruit fly first found in 2008 damaging fruit in many California counties. The traps used were all of the clear “deli cup” design. In Minnesota, SWD primarily attacks raspberries, blackberries (and other cane berries), blueberries, strawberries and wine grapes. Spotted wing drosophila (SWD) is a member of the “small fruit fly” or “vinegar fly” genus Drosophila. Strik B (2005) Growing Kiwifruit. There are black stripes down its abdomen. Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. The female even has a special egg-laying organ that is serrated like a saw, so she can lay her eggs inside ripening fruit. Photo by John Davis. The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. Spotted Wing Drosophila Larvae in Blueberry; photo by David Handley. We are slowly learning to live with it in Wisconsin since its first detection in 2010. 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. This method is effective from removing D. suzukii from gardens and small areas but is difficult for farmers with larger operations to do this. Only adults overwinter successfully in the research conducted thus far. College of Agricultural Sciences [3] Generations hatched early in the year have shorter lifespans than generations hatched after September. It became established in Hawaii during the 1980’s, and was first discovered in the continental United States in California in 2008. Introduction. If adult SWD are present on your farm, manage them aggressively. 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. Spotted wing drosophila (SWD) is a vinegar (fruit) fly that was first reported in Britain in 2012. [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. Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. 2009). Biological control of the Spotted wing Drosophila - Drosophila suzukii. After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. Today, it has spread throughout most of the continental US. While it is not possible to distinguish SWD larvae from those of other common vinegar flies, the presence of larvae in intact fruit … 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. Spotted wing drosophilas are a global pest. 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. Native to Asia, SWD is currently found in most of the primary fruit growing regions of the U.S. [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 adults and larvae closely resemble the common vinegar … “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. [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, Drosophila suzukii (Matsumura) a new fruit pest of concern especially for strawberry, blackberry and blueberry growers. 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. [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. 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. 2017) using USDA production data. Unlike its vinegar fly relatives which are primarily attracted to rotting or fermented fruit, female D. suzukii attack fresh, ripe fruit by using their saw-like ovipositor to lay eggs under the fruit's soft skin. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. Spotted wing drosophila.

Save to My scrapbook Many species of fruit flies are present in late summer; most normally infest overripe, fallen, decaying fruit, so are not crop-limiting pests. See: EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. Adult … Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. Spotted Wing Drosophila. 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. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. The pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. It was first detected in the North Central region of the US in Michigan in 2010, and has spread rapidly. Spotted wing drosophila (SWD) is a vinegar (fruit) fly that was first reported in Britain in 2012. [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota in 2012. 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. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. 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. The female has a long, sharp, serrated ovipositor. Drosophila suzukiiadults are small (3–4 mm) yellowish-brown flies with red eyes. Introduction; Recognizing fruit damage; For more information; Introduction. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. 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. 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. Spotted wing drosophila is native to Southeast Asia, preferring temperatures of 20-30 °C. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. The spotted wing Drosophila (SWD) is a vinegar or fruit fly of East Asian origin. 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. The foreleg of the male sports dark bands on the first and second tarsi. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. It was discovered in western Washington, Oregon and British Columbia in 2009, and in eastern Washington in June of 2010. Whenever travelling to New Zealand, always declare any food or fruit in your luggage. Most types of sprays need to be applied each week, at a minimum. 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). [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. 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. 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 is a small vinegar fly from East Asia that lays its eggs in softer, thin-skinned fruits, such as berries. It attacks a range of soft skinned fruit and reduces crop yield and quality through direct feeding damage and secondary infection of the fruit. In efficacy rankings, Delegate® WG insecticide has performed well in the battle against spotted wing drosophila. The larvae grow inside the fruit. Timing of the sprays is important to effectively controlling it. A field study was conducted in 2013 to evaluate various baits for monitoring spotted wing drosophila. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. Spotted-wing drosophila is a small fly that develops within many kinds of fruits. 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. 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. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. Spotted Wing Drosophila A new invasive pest of Michigan fruit crops Rufus Isaacs and Noel Hahn, Department of Entomology Bob Tritten and Carlos Garcia, MSU Extension MSU Extension Bulletin E-3140 New • October 2010 Introduction The Spotted Wing Drosophila (SWD) is a small vinegar fly with the potential to damage many fruit crops. 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. The spotted wing drosophila is an invasive pest from Asia, first discovered in California in 2008. Therefore, expert examination by a specialist is needed for positive identification and confirmation (Steck et al. It was first identified in British Columbia in 2009. [12] Larvae may leave the fruit, or remain inside it, to pupate. The spotted wing drosophila is most likely to get to New Zealand in fruit infested with eggs or maggots. Oregon State University, University of Idaho and Washington State University. The now infamous Spotted Wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly from Eastern Asia that can cause significant damage to soft-fleshed fruit. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. Two- to three-millimeters long, the spotted wing drosophila fly first drew attention in 2008 in California. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. 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.). 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. 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. The spotted wing drosophila is an invasive fly that first arrived in the United States in 2008, Lahiri says, eventually making its way nationwide … Larvae are small, legless, up to 1/8 inch long, cream colored and … The flies are most prevalent in the lower, shaded parts of the plants. There are different types of traps, both commercial and home-made, that are effective in monitoring it. [42] This fly is also infected with a variety of viruses in the wild. This is not the case with SWD. Spotted-wing drosophila, however, attacks undamaged fruit prior to harvest. 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". Oregon State University Detections were made for the first time in Utah and Michigan in late summer/fall of 2010. Wasps native to the Northwest aren’t much of a threat to SWD. The lifespan of D. suzukii varies greatly between generations; from a few weeks to ten months. (Accessed November 2009). The spotted wing drosophila will attack thin-skinned fruit such as raspberry, blackberry, blueberry, strawberry, cherry, plum, peach, nectarine, and sometimes grape. That makes the SWD a menace to a wide variety … It looks very much like other fruit flies, but unlike most fruit flies, which attack rotting or over-ripe fruit, SWD attacks healthy, undamaged 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. SWD are very similar in size, shape and appearance to other vinegar flies (i.e. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. [8][9], D. suzukii has a slow rate of evolution due to its lower number of generations per year, because it enters winter diapause. 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. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. Spotted wing drosophila adults can be blown by wind to nearby locations or transported to new regions via infested fruit. 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.
