$500M. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. This material is based upon work supported by the [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. Search in featureTaxon InformationContributor GalleriesTopicsClassification. The small fruit flies are familiar insects to many people, sometimes found abundantly indoors, where they feed on yeasts associated with overripe fruit or the sediment of beverage containers. 4.

[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]. Males have dark spots on the wingtips and black combs on the forelegs. Ian Keesey is injecting a headspace odor collection sample from plant tissue into the GC-MS for separation, analysis and identification. Control of D. suzukii is critical since there is no tolerance for infested fruit in the market. After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. Origin. Spotted-wing drosophila Drosophila suzukii (Matsumura) is one of the most important invasive pests of fruit and wine production worldwide. Drosophila suzukii is native to southeast Asia and is widely distributed in China, India, Korea, Myanmar, Russia and Thailand (Toda 1987, Oku 2003, Hauser et al. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Geospatial data is one of the sources currently less investigated. Drosophila suzukii, unlike the fruit fly and other similar species, which are mainly attracted to rotten fruit, attacks fresh and ripe fruit, depositing eggs under the epidermis. Origin Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. The content of the bottle is poured into the ECONEX BOTTLE TRAP DS, which –after that– must be hanged in an appropriate place, in order to capture Drosophila suzukii. [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. 4. The Animal Diversity Web is an educational resource written largely by and for college students. The global fresh fruit trade, coupled with the ability of the larvae to hide inside the fruit undetected until after transportation, facilitate their distribution. 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. Suzukii Drosophila: a new threat feature for the European fruit and viticulture - report for the international conference in Trient, 2, December 2011. This species, whose development is very dependent on temperature and high relative humidity, can attack a very wide range of cultivated and wild fruits. Most types of sprays need to be applied each week, at a minimum. Translated from Japanese by Shinji Kawaii. [6] The larvae are small, white, and cylindrical reaching 3.5 millimetres (9⁄64 in) in length.[4]. 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 lifespan of D. suzukii varies greatly between generations; from a few weeks to ten months. Thus, in order to identify important evolutionary shifts in olfaction, the antennae and large basiconic sensillae of To cite this page: It is distinguished from the vinegar mosquito by having the males at the tip of its wings a gray spot. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Goals / Objectives Aim 1.1 Electrophysiological screen for affordable, safe, DEET-like repellents for flies: We propose to express the Drosophila suzukii Ir40a gene, in an ectopic expression system "empty neuron" on the D. melanogaster antenna. 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 simulation and prediction of D. suzukii's population dynamics would be helpful for guiding pest management. In 2014, more spotted-wing Drosophila suzukii than ever before were observed in Germany. Journal fur Kulturpflanzen, 64:68-72 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 SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Their research results may help to develop more efficient traps in order to simplify Drosophila suzukii monitoring and to better keep this pest in check. D. suzukii were allowed to oviposit on two early–, two middle– and two late–maturing varieties of nectarine—Shuguang and Chunguang, Fengguang and Zhong you 4, Zhong you 7 and Zhong you 8, respectively and the number of larvae also followed the order. & nbsp; Larvae: at first sight they are similar to those of other drosophilas, they are whitish color and small size (only 3.5mm long at the end of their development). National Science Foundation Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. & nbsp; Lar… The invasive pest Drosophila suzukii is characterized by a specific fresh-fruit targeting behavior and has quickly become a menace for the fruit economy of newly infested North American and European regions.D.suzukii carries a strain of the endosymbiotic bacterium Wolbachia, named wSuz, which has a low infection â ¦ Drosophila suzukii. Drosophila suzukii (Spotted Wing) Description SWD is a small fly (2 to 3 mm) with bright red eyes, a pale brown thorax, and an abdomen with black horizontal stripes. Males have dark spots on the wingtips and black combs on the forelegs. Whilst sharing some natural viruses with its close relative D. melanogaster, D. suzukii also harbours a number of unique viruses specific to it alone. Overview Origin Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Within Europe, this species is also widely distributed in France, Italy and Spain (European and Mediterranean … Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. [44][45][46] The yeast species found to be most frequently associated with D. suzukii were Hanseniaspora uvarum, Metschnikowia pulcherrima, Pichia terricola, and P. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. Males have dark spots on the wingtips and black combs on the forelegs. Origin. Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students.ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Drosophila suzukii Klasifikasi ilmiah; Kingdom: Animalia: Phylum: Arthropoda: Class: Insecta: Order: Diptera: Family: Drosophilidae: Genus: Drosophila: Species: Males have dark spots on the wingtips and black combs on the forelegs. Confused by a class within a class or The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Spotted-wing drosophila (Drosophila suzukii)2 is a member of the “small fruit fly” or “vinegar fly” genus Drosophila. Accessed at https://animaldiversity.org. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. [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. [21] As D. suzukii continues to spread, most of the states will most likely observe it. 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. The Animal Diversity Web team is excited to announce ADW Pocket Guides! 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. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. [12] Larvae may leave the fruit, or remain inside it, to pupate. 5. Seasonal polyphenism in Drosophila suzukii manifests itself in two discrete adult morphotypes, the “winter morph” (WM) and the “summer morph” (SM). In addition, the opening of the trap is designed in such a way as to ensure that pollinators are not captured. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted wing drosophila (SWD), is the most important pest affecting berry crop production worldwide. Males have dark spots on the wingtips and black combs on the forelegs. Help us improve the site by taking our survey. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. Adults emerge from overwintering when temperatures reach approximately 10 °C (50 °F) (and 268 degree days). Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. [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. Welcome to the National Drosophila Species Stock Center (NDSSC) Homepage. June-bearing strawberries may escape injury, whereas late summer fruit on day-neutral varieties may suffer damage. (Rosaceae), Vaccinium spp. [42] This fly is also infected with a variety of viruses in the wild. [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. The spotted wing Drosophila (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an invasive vinegar fly unintentionally introduced from Asia. [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. The foreleg of the male sports dark bands on the first and second tarsi. [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. This species, whose development is very dependent on temperature and high relative humidity, can attack a very wide range of cultivated and wild fruits. Drosophila suzukii is an invasive polyphagous pest of wild and cultivated soft‐skinned fruits, which can cause widespread economic damage in orchards and vineyards. [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. (Ericaceae), Vitis spp. Timing of the sprays is important to effectively controlling it. The SWD was first detected in 2008 in the western United States and it has since rapidly spread [17] In Fall 2010 the fly was also discovered in Michigan[18] and Wisconsin. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. Identification, Biology, and Life Cycle. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. The larvae hatch and grow in the fruit, destroying the fruit's commercial value. Drosophila suzukii, unlike the fruit fly and other similar species, which are mainly attracted to rotten fruit, attacks fresh and ripe fruit, depositing eggs under the epidermis. 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. © 2020 Regents of the University of Michigan. [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. Genus species: Drosophila suzukii Crops of concern: Raspberries, blackberries, and blueberries are at high risk of SWD infestation. Drosophila suzukii, like all insects, is host to a variety of microorganisms. 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 trap is red, which is the colour that strongly attracts the fruit fly. There are different types of traps, both commercial and home-made, that are effective in monitoring it.

[24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. It differs from other species of drosophilas by having a sawed oviscapto(organ used for laying eggs) that allows it to attack healthy fruits. 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". Fall-bearing and late maturing varieties are at greater risk than early maturing ones. D. suzukii were allowed to oviposit on two early–, two middle– and two late–maturing varieties of nectarine—Shuguang and Chunguang, Fengguang and Zhong you 4, Zhong you 7 and Zhong you 8, respectively and the number of larvae also followed the order. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. A female may lay as many as 300 eggs during its lifespan. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. 2021. The spotted wing drosophila (Drosophila suzukii) is a newly introduced pest of soft fruits,stone fruits and grapes in Europe. Our Collection. A typical example of always increasing data set is that produced by the distribution data of invasive species on the concerned territories. tem that is more attractive to D. suzukii than any of its other similar Drosophila relatives, thus making sorting and counting trapped flies difficult if not impossible for those in-volved in IPM efforts. Even though its main hosts belong to the genera Prunus and Rubus, its high polyphagy and adaptability to new environments makes it a serious problem for farmers worldwide, who have reported several economic losses because of this pest. insidiosus. In order to avoid contamination with foreign microorganisms of the labo-ratory, samples were reared under microbiologically con- The spotted wing drosophila fly, Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae), is a pest which caused serious crop losses to soft-skinned fruits such as cherries, strawberries, and grapes. [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. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. Myers, P., R. Espinosa, C. S. Parr, T. Jones, G. S. Hammond, and T. A. Dewey. Drosophila suzukii is a vinegar fly that looks similar to drosophila melanogaster. [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. Males have dark spots on the wingtips and black combs on the forelegs. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. 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. These morphotypes are known to differ in thermal stress tolerance, and they co‐occur during parts of the year. (Drosophila suzukii: eine neue bedrohung fur den Europaischen obst- und weinbau - bericht uber eine internationale tagung in trient, 2, Dezember 2011.) Control of D. suzukii is critical since there is no tolerance for infested fruit in the market. Please see our brief essay. Photo: Anna Schroll. The spotted-wing drosophila, Drosophila suzukii Matsumura, is an invasive pest causing significant damage to soft skinned fruits. [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. Spotted Wing Drosophila. The insect resembles common vinegar flies in the genus Drosophila. SPOTTED WING DROSOPHILA (Drosophila suzukii) Although there are native species of fruit or vinegar flies in North America, the spotted wing drosophila (SWD) is a relatively new introduction that damages certain fruit crops throughout the country. In addition, the opening of the trap is designed in such a way as to ensure that pollinators are not captured. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. Disclaimer: [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota 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. The Spotted Wing Drosophila (SWD), Drosophila suzukii (Matsumura), is a harmful insect pest for soft fruit cultivations. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. The Drososan trap has been specifically designed to combat the Drosophila suzukii fruit fly. [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 oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. The Animal Diversity Web (online). Only adults overwinter successfully in the research conducted thus far. Kanzawa. The Drososan trap has been specifically designed to combat the Drosophila suzukii fruit fly. This pest lays its eggs in fresh and ripening fruits before they … 2009). Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Fly Drosophila suzukii male (left) and female (right) [/ caption] The adults of this insect are flies with a size of 2-3mm, light yellowish-brown thorax, red eyes and abdomen with black bands. The spotted-wing drosophila, Drosophila suzukii Matsumura, is an invasive pest causing significant damage to soft skinned fruits. 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. 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. [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. (Enterobacteriaceae). [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. ECONEX DROSOPHILA SUZUKII LIQUID ATTRACTANT is a bottled active substance. (Vitaceae), and other soft fruits. [3] Generations hatched early in the year have shorter lifespans than generations hatched after September. To prevent resistance to certain sprays, farmers must rotate among different insecticides. This species feeds on Prunus spp., Rubus spp., Fragaria spp. Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. Economic impacts are significant; losses from large scale infestation (20% loss) across the US alone could equate to farm gate impacts > $500M. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. This material is based upon work supported by the [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. Search in featureTaxon InformationContributor GalleriesTopicsClassification. The small fruit flies are familiar insects to many people, sometimes found abundantly indoors, where they feed on yeasts associated with overripe fruit or the sediment of beverage containers. 4.
