Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. Management-chemical control: HOME USE. [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]. Adults: Florida is home to at least 27 addiional Drosophila spp. 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. Genus species: Drosophila suzukii Growers: Talk to your local CCE agent about monitoring SWD. Introduction. OMRI-listed for organic use. In other temperate climates, the spotted wing drosophila overwinters as an adult in protected areas, … [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. Timing of the sprays is important to effectively controlling it. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. 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. "Quantifying Host Potentials: Indexing Postharvest Fresh Fruits for Spotted Wing Drosophila, "Integrating Circadian Activity and Gene Expression Profiles to Predict Chronotoxicity of, "Substrate Vibrations During Courtship in Three, "High Hemocyte Load is Associated with Increased Resistance Against Parasitoids in, https://en.wikipedia.org/w/index.php?title=Drosophila_suzukii&oldid=998411981, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 January 2021, at 07:28. 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. Native to Asia, SWD is currently found in most of the primary fruit growing regions of the U.S. Corvallis, Oregon 97331. 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. In efficacy rankings, Delegate® WG insecticide has performed well in the battle against spotted wing drosophila. (Enterobacteriaceae). Introduction; Recognizing fruit damage; For more information; Introduction. 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. 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. Since D. suzukii is more active in the morning and evening those are the best times to control it. Growers and researchers are working together to implement effective pest control strategies. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. The spotted-wing drosophila can be distinguished from the western cherry fruit fly, Rhagoletis indifferens, by comparing anatomical features of the maggots and wing patterns of adult flies. kaolin clay (Surround at Home)-Repels some insect pests when applied as a spray to leaves, stems, and fruit. The foreleg of the male sports dark bands on the first and second tarsi. Integrated pest management (IPM) programs for the spotted-wing drosophila Drosophila suzukii (Diptera: Drosophilidae) rely on insecticide applications to reduce adult populations and prevent fruit infestation. 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. A field study was conducted in 2013 to evaluate various baits for monitoring spotted wing drosophila. 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. It attacks a range of soft skinned fruit and reduces crop yield and quality through direct feeding damage and secondary infection of the fruit. Spotted wing drosophila. If you are not getting the level of control you expect, here are a … Traps that use apple cider vinegar with a whole wheat dough bait have been successful for farmers to both capture and monitor D. There are black stripes down its abdomen. 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. After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. Strik B (2005) Growing Kiwifruit. Although monitoring traps are used for early D. suzukii adult detection to time the start … The most distinguishable trait of the adult is that the males have a black spot towards the tip of each wing. Only adults overwinter successfully in the research conducted thus far. Disseminating the most current scientific knowledge of Spotted Wing Drosophila fruit fly biology, management, and effects on Pacific Northwest berry crops. Wasps native to the Northwest aren’t much of a threat to SWD. The larvae grow inside the fruit. 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. Two- to three-millimeters long, the spotted wing drosophila fly first drew attention in 2008 in California. Adult … Spotted wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly native to Southeast Asia. [3] Generations hatched early in the year have shorter lifespans than generations hatched after September. The spotted wing drosophila is an invasive pest from Asia, first discovered in California in 2008. 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. [8][9], D. suzukii has a slow rate of evolution due to its lower number of generations per year, because it enters winter diapause. The female even has a special egg-laying organ that is serrated like a saw, so she can lay her eggs inside ripening fruit. This is not the case with SWD. See: EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. Spotted wing Drosophila (SWD), Drosophila suzukii, is an invasive vinegar fly native to Southeast Asia. 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.). It made its way into New York by 2011. A Pacific Northwest Extension Publication, PNW 507. To enable basic and applied research of this important pest, we sequenced the D. suzukii ge … [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. Save to My scrapbook [6] The larvae are small, white, and cylindrical reaching 3.5 millimetres (9⁄64 in) in length.[4]. Introduction. The lifespan of D. suzukii varies greatly between generations; from a few weeks to ten months. Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. . [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. Adult flies are smaller than 4mm, colored light brown with red eyes. Spotted-wing drosophila, however, attacks undamaged fruit prior to harvest. Oregon State University Drosophila suzukii, like all insects, is host to a variety of microorganisms. The adults and larvae closely resemble the common vinegar … This summer the SWD was captured … Drosophila suzukii. Adult SWD are small, 1/16 to 1/8 in long (2‐3 mm) with red eyes and a light brown thorax and abdomen. Biological control of the Spotted wing Drosophila - Drosophila suzukii. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. Spotted wing drosophila is native to Southeast Asia, preferring temperatures of 20-30 °C. 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. The spotted wing drosophila (SWD), Drosophila suzukii, is a small fruit fly (vinegar fly) native to Japan.It was first discovered in the western United States in 2008 and has quickly moved through the Pacific Northwest into other parts of the US and northward into Canada. Due to its rapid reproductive rate and their ability to use over 100+ fruits for reproduction makes management of … It is now widespread in Coastal and Interior fruit growing areas of B.C. [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. The antennae are short and stubby … Spotted wing drosophila (SWD) is a vinegar (fruit) fly that was first reported in Britain in 2012. Unlike most other vinegar flies it can damage otherwise unblemished soft and stone fruit including strawberries, raspberries, blackberries, currants, blueberries, grapes, cherries and plums. Spotted wing drosophila (SWD) is a member of the “small fruit fly” or “vinegar fly” genus Drosophila. [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. insidiosus. There are black stripes down its abdomen. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. [21] As D. suzukii continues to spread, most of the states will most likely observe it. [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. [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. “Spotted wing drosophila is by far the fastest spreading pest I’ve ever seen,” Beers said. Spotted wing drosophila is a small vinegar fly from East Asia that lays its eggs in softer, thin-skinned fruits, such as berries. 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; 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. 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. Therefore, expert examination by a specialist is needed for positive identification and confirmation (Steck et al. I have had some reports of poor control. Larvae are small, legless, up to 1/8 inch long, cream colored and … It is particularly damaging to late fruiting plantings of raspberries, blackberries, and strawberries. It infests ripening cherries throughout the state and ripening raspberry, blackberry, blueberry, and strawberry crops, especially in coastal areas. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. 2017) using USDA production data. Adults are small (2–3 mm) flies with red eyes, a pale brown thorax, and abdomen with black stripes. acetamiprid-In field tests, this product has provided inconsistent control of SWD. One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. Generally, soft-skinned fruit become vulnerable to attack as they begin to soften and tur… Most types of sprays need to be applied each week, at a minimum. 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 oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". 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. 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 … Spotted Wing Drosophila Larvae in Blueberry; photo by David Handley. SWD are very similar in size, shape and appearance to other vinegar flies (i.e. Growers and researchers are working together to implement effective pest control strategies. A female may lay as many as 300 eggs during its lifespan. There are different types of traps, both commercial and home-made, that are effective in monitoring it. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. 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. [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota in 2012. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. The most distinguishable trait of the adult is that the males have a black spot near the tip of each wing. College of Agricultural Sciences Spotted Wing Drosophila. 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). 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. Fruit flies (also called vinegar flies) are often associated with damaged, overripe, or rotting fruits and vegetables. [30], Earwigs,[39] damsel bugs,[39] spiders,[39] ants,[39] and Orius ("minute pirate bugs")[39] especially O. It became established in Hawaii during the 1980’s, and was first discovered in the continental United States in California in 2008. For pest description, crop damage, biology, life history, sampling and cultural management. The Spotted Wing Drosophila (SWD) is a vinegar fly of East Asian origin that can cause damage to many fruit crops. EMERGING PEST: Spotted Wing Drosophila-A Berry and Stone Fruit Pest. Spotted wing drosophila (SWD), Drosophila suzukii(Matsumura), is an exotic pest of 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. Spotted wing drosophila (SWD) is a fruit fly that's on the move. Adults emerge from overwintering when temperatures reach approximately 10 °C (50 °F) (and 268 degree days). [42] This fly is also infected with a variety of viruses in the wild. [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 (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. The larvae hatch and grow in the fruit, destroying the fruit's commercial value. The spotted wing drosophila will attack thin-skinned fruit such as raspberry, blackberry, blueberry, strawberry, cherry, plum, peach, nectarine, and sometimes grape. Spotted Wing Drosophila. “Spotted wing drosophila have small, white legless larvae with no apparent head, and damaged fruit often feels soft and leaks juice,” Hamby says. To prevent resistance to certain sprays, farmers must rotate among different insecticides. 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. 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 a temperate fruit fly, native to Southeast Asia; preferring temperatures of 20-30 o C. It is known to infest thin-skinned fruit. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. The traps used were all of the clear “deli cup” design. 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. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. 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. suzukii. 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 discovered in western Washington, Oregon and British Columbia in 2009, and in eastern Washington in June of 2010. It became established in Hawaii during the 1980’s, and was first discovered in the continental United States in California in 2008. Damage: Spotted Wing Drosophila in Ontario Table of Contents. Aggressive management entails: 1. Spotted Wing Drosophila: What we learned in 2014 and outlook into the 2015 field season . Spotted wing drosophila. Spotted wing drosophila (SWD) is a fruit fly that's on the move. Some of these could easily be confused with Drosophila suzukiidue to their spotted wings. It is a fruit-killing machine. [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. 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 fly called spotted wing drosophila (SWD, Drosophila suzukii) is emerging as a global plant pest of significance. University of Maine Cooperative Extension shows how to identify the damage caused by Spotted Wing Drosophila. “We see good to excellent control with Delegate,” Hamby says. Spotted wing drosophila (SWD), Drosophila suzukii, is a fruit fly first found in 2008 damaging fruit in many California counties. 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. The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. 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. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. 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 is a small fly that develops within many kinds of fruits. 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. Drosophila suzukii Matsumura (Diptera: Drosophilidae), a fruit fly from East Asia, is now a serious economic pest of soft fruits and berries across Europe, the Americas and North Africa. 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. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. 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. Detections were made for the first time in Utah and Michigan in late summer/fall of 2010. The spotted wing Drosophila (SWD) is NOT that kind of fruit fly. 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. Observed in Japan as early as 1916 by T. Kanzawa,[3] it was widely observed throughout parts of Japan, Korea, and China by the early 1930s. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. Steck GJ, Dixon W, Dean D (2009) Spotted Wing Drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a fruit pest new to North America. SWD quickly spread throughout the Pacific Northwest and Canada, and was found in Florida in 2009. Spotted Wing Drosophila. The pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. Translated from Japanese by Shinji Kawaii. Spotted wing drosophila continue to plague raspberry, blackberry, blueberry, and grape growers. Photo by John Davis. Biology Spotted wing drosophila (SWD), Drosophila suzukii (Matsumura), is an exotic pest of Asian origin. Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable small fruit and tree fruit crops. 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. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. 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. Many species of fruit flies are present in late summer; most normally infest overripe, fallen, decaying fruit, so are not crop-limiting pests. 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. 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. 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. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). It was first detected in the North Central region of the US in Michigan in 2010, and has spread rapidly. 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.
