Here we present the draft genome of Tatumella sp. [27], Farmers have the option of both conventional and organic sprays [28] to control D. suzukii. Geographical distributions and host associations of larval parasitoids of frugivorous, Molina JJ, Harisson MD, Brewer JW. The spotted wing drosophila fly, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an invasive species that can lay eggs in intact soft-skinned fruits by their advanced ovipositor (Yu et al. Figure 3. Microorganisms play a central role in the biology of vinegar flies such as Drosophila suzukii and Drosophila melanogaster: serving as a food source to both adults and larvae, and influencing a range of traits including nutrition, behavior, and development. Pupation can occur either inside or on the exterior of fruit. Since D. suzukii is more active in the morning and evening those are the best times to control it. 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. Chemical control. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. 1990. [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. This wound can be a point of entry for fungi such as the monilia. [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. Figure 5. 2002. Translated from Japanese by Shinji Kawaii. The total life cycle may be completed within one to two weeks depending upon the climatic conditions (Kanzawa 1939). [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. Figure 10. The foreleg of the male sports dark bands on the first and second tarsi. Ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), lateral view. The spotted wing Drosophila is a small fly (2 to 3.5 mm) yellow-brown in colour with transverse black rings across the abdomen and protruding brick-red eyes. Drosophila suzukii; SWD) larval infestation. 2010). The effect of entomopathogenic fungi on Drosophila suzukii larvae, pupae andadult flies is currently being fully tested. Wing of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). 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. Drosophila suzukii has a wide host range, including: The following hard fruits may be attacked if the skin is already broken: Fruit infestation is initially manifested by scars on the fruit surface left by ovipositing females (stinging). Adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). (Kanzawa 1939, Dubuffett et al. However, traps baited with yeast-sugar-water mixtures facilitate easy identification of flies because of the clear color of the bait material. Preliminary research from Oregon suggests that Drosophila suzukii larvae, pupae, and adults have the potential to survive fluctuating overwintering conditions for periods up to 60 days. This procedure emerged as the most reliable of several methods tested at Oregon State University. III. Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. The niches utilized by the fly species partially overlap, as do the microbiota that sustain them, and interactions among these players may drive the … Kanzawa. The female has a long, sharp, serrated ovipositor. Drosophila suzukii is an emerging global pest of soft fruit; although it likely overwinters as an adult, larval cold tolerance is important both for determining performance during spring and autumn, and for the development of temperature-based control methods aimed at larvae. However, Drosophila suzukii is firmly established on the island of Hokkaido in Japan where winters average -4 to -12°C (Kimura 2004), suggesting the possibility of its establishment in cooler climates. One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. (Enterobacteriaceae). 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. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. 2011). The fruit fly D. suzukii is a fruit crop pest and is a serious economic threat to soft summer fruit. The Tomakomai Experiment Forest, Hokkaido University. First instar larvae are approximately 0.07 mm in length. [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. [12] Larvae may leave the fruit, or remain inside it, to pupate. In general, Drosphila spp. Photograph by Martin Hauser, California Department of Food and Agriculture. Good field sanitation is critical to prevent further spread of flies. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Drosophila suzukii is a serious economic pest and we determined the conditions for adult reproductive diapause by the females in our previous studies. kluyveri. Infested fruit collapse around the feeding site very rapidly and rot due to mold or secondary infections (Beers et al. Drosophila species are found all around the world, with more species in the tropical regions. Bucket-style traps or quart containers used for monitoring other Drosophila flies can be effectively used for monitoring Drosophila suzukii.

(no longer available online), Davidson JK. Photograph by Martin Hauser, California Department of Food and Agriculture. Figure 6. are very sensitive to desiccation. Drosophila suzukii prefers a moderate climate but can also survive in cold conditions (Kanzawa 1939). 2011). The eggs are laid singly and are randomly distributed on fruits. Cultural control. 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. [21] As D. suzukii continues to spread, most of the states will most likely observe it. It really is not a fruit fly. Drosophila flies are sometimes called small fruit flies. Adults: Florida is home to at least 27 addiional Drosophila spp. 1988. Drosophila made their way to the Hawaiian Islands and radiated into over 800 species. The fly called spotted wing drosophila (SWD, Drosophila suzukii) is emerging as a global plant pest of significance. These fruits are full of yeasts and have a high protein content.The larvae then develop and grow on a proteinic diet. Drosophila suzukii is a severe economic invasive pest of soft-skinned fruit crops. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. 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.). Research Bulletin of College Experiment Forests. suzukii. D. suzukii is an economically damaging pest because the females are able to infest thin-skinned fruits before harvest and the larvae destroy the fruit pulp by feeding. Insecticide sprays effective against other Drosophila flies are also effective against Drosophila suzukii adults. 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. Drosophila or pomace flies are small insects commonly found in association with over-ripened or rotten fruits and vegetables. Figure 1. Most types of sprays need to be applied each week, at a minimum. (February 2010). Spotted wing drosophila (SWD), Drosophila suzukii, is a fruit fly first found in 2008 damaging fruit in many California counties.It infests ripening cherries throughout the state and ripening raspberry, blackberry, blueberry, and strawberry crops, especially in coastal areas. This method is effective from removing D. suzukii from gardens and small areas but is difficult for farmers with larger operations to do this. Adults emerge from overwintering when temperatures reach approximately 10 °C (50 °F) (and 268 degree days). 2007. 1999). Therefore, all nearby sources of fruit should be managed to eliminate flies (Ministry of Agriculture and Lands, British Columbia 2009). Larval development occurs inside the fruit and develops through three instars before pupation. Addition of a small drop of dish soap as a surfactant or placement of a sticky card within the traps improves trap efficiency by retaining the flies which have already entered the traps. In this project we are focusing on finding natural enemies (parasitoids) of the pest to introduce into Europe. 2013; Ioriatti et al. (February 2010). Within Europe, this species is also widely distributed in France, Italy and Spain (European and Mediterranean Plant Protection Organization 2010). Among these, Drosophila suzukiiMatsumura (Diptera, Drosophilidae), or spotted wing drosophila, a fly of East Asian origin, was first found in 2008 in Europe and North America, from where it invaded several other regions (Fraimout etal., 2017). Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. However, a few species such as the spotted-wing drosophila, Drosophila suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. Adult females of Drosophila Suzukii damage the surface of the cherry during laying. Within the United States, it has been established in Hawaii since 1980 (Kaneshiro 1983). on overripe banana. [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. Photograph by Martin Hauser, California Department of Food and Agriculture. Yeasts occurring in, Dubuffet A, Colinet D, Anselme C, Dupas S, Carton Y, Poirié M. 2009. Orius insidiosus has been reported to feed exclusively on Drosophila suzukii. Drosophila or pomace flies are small insects commonly found in association with over-ripened or rotten fruits and vegetables. [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 females have a serrated ovipositor with which they penetrate the fruit skin. 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. Figure 12. 1957. Mature larvae may grow up to 6 mm in length (Kanzawa 1939, Walsh et al. [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. SEM of an ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), lateral view. 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. 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 has shown itself to be highly opportunistic and it has been able to adapt to a wide range of host plant fruit for rearing its larvae and for adult feeding. [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 flies are most active at 20°C (68°F). Photograph by Martin Hauser, California Department of Food and Agriculture. Kimura MT. 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. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. Agriculture and Resource Economics Update. http://www.eppo.org/QUARANTINE/Alert_List/insects/drosophila_suzukii.htm, Spotted wing drosophila (Fruit fly) Pest alert, Spotted wing drosophila new in Florida berry culture, Spotted wing drosophila could pose threat for Washington fruit growers. Regularly stir the solution to bring larvae to the surface and to break Drosophila suzukii The oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". The pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. Like most Drosophila spp., reproduction in Drosophila suzukii is rapid. 2011). (August 2010). Bradley TJ, Williams AE, Rose MR. 1999. [30], Earwigs,[39] damsel bugs,[39] spiders,[39] ants,[39] and Orius ("minute pirate bugs")[39] especially O. There are different types of traps, both commercial and home-made, that are effective in monitoring it. Vertical microdistribution of Drosophilidae (Diptera) within various forests in Hokkaido. 2011). The species is endemic in Asia. 2009). This strain was isolated from Drosophila suzukii larvae as part of a larger project to study the microbiota of D. suzukii . strain UCD-D_suzukii, the first member of this genus to be sequenced. 2009). Pupae: The pupae are cylindrical, reddish brown with two small projections at the end. D. suzukii is an economically damaging pest because the females are able to infest thin-skinned fruits before harvest and the larvae destroy the fruit pulp by feeding. [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. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. Figure 2. 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. Physiological responses to selection for desiccation resistance in, Bolda MP, Goodhue RE, Zalom FG. This increases the danger of D. suzukii to human health, as the consumption of what appear to be normal fruits that contain drosophila larvae can lead to conditions such as intestinal myiasis. As a result of its willingness to explore and test novel fruit species, it has become extremely polyphagous. A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. Figure 9. Figure 11. Figure 7. Drosophila flies are weak fliers but spread easily through infested fruits or by wind. The antennae are short and stubby with branched arista. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. However, the role of beneficial organisms in management of Drosophila suzukii has not been fully ascertained (Walsh et al. Many of the larvae will exit right away; the majority will exit fruit within 1 to 15 minutes. Activity becomes reduced at temperatures above 30°C (86°F) or below freezing. In the continental U.S., it was first detected in Santa Cruz County, California, on caneberry and strawberry plants (Bolda et al. b) Count larvae immediately—before they die and possibly sink to bottom of tray. 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 foreleg of the male sports dark bands on the first and second tarsi. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. Photograph by Martin Hauser, California Department of Food and Agriculture. The research was conducted in collaboration with the U.S. Department of Agriculture, Agricultural Research Service, Horticulture Crops SEM of genitalia of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). However, they both survived a short (24 h) exposure at a similarly high temperature (30.6 °C in the egg-laying phase of the parasitoid fecundity assessment) showing that the adverse effect of high temperature extremes depends, in part, on the … The adult female of Drosophila melanogaster (our beloved model organism), lays her eggs on overripe or rotting fruits. Steck GJ, Dixon W, Dean D. (August 2009). 2011). The larvae hatch and grow in the fruit, destroying the fruit's commercial value. However, true fruit flies belong to the family Tephritidae. The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. Ripe fruit should be picked frequently to minimize population buildup. Drosophila suzukii (Matsumura) (Diptera: Drosophila) is an invasive frugivore and has become a significant pest of small fruit, cherry and grape throughout the United States. 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. Economic losses have now been reported across North America and in Europe as the fly has spread to new areas. Hauser M, Gaimari S, Damus M. (October 2009). [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. In addition, males have two rows of combs on each fore tarsus which are absent in females. 44: 611-632. Drosophilaflies are sometimes called small fruit flies. Larvae of Drosophila spp. Figure 4. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. The Metarhizium Brunneum fungus even causesa death of nearly 90% of fruit flies after ten days. Photograph by Martin Hauser, California Department of Food and Agriculture. Drosophila suzukii is native to East Asia and has spread to Europe, Asia, Africa, the Americas, and Oceania [ 7 ]. Spotted wing drosophila. 2006, Walsh et al. They are approximately 2–3 mm long. Multiple clutches of larvae may be present on the same fruit because females may oviposit on the same fruit (Kanzawa 1939, Mitsui et al. Flies could survive up to 10 generations per year under California climate conditions (Walsh et al. All damaged fruit should be removed from the field and destroyed, either by burial or disposal in closed containers. [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. In addition, it alsoreduces the fertility of the flies (during these ten days), resulting in feweroffspring20. 2011). including Drosophila melanogaster. The body is tapered anteriorly with elevated posterior spiracles. Like other members of the Drosophilidae, D. suzukii is small, approximately 2 to 3.5 millimetres ( ⁄64 to ⁄64 in) in length and 5 to 6.5 millimetres ( ⁄64 to ⁄4 in) in wingspan and looks like its fruit and vinegar fly relatives. SEM of an ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), posterior view. … 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. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. (December 2009). Mitsui H, Achterberg VK, Nordlander G, Kimura MT. There are approximately 1,500 known species in the genus Drosophila (Markow and O'Grady 2006). There are approximately 1,500 known species in the genus Drosophila (Markow and O'Grady 2006). Biological control. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. The eggs develop and hatch within the fruit in which they are laid (Walsh et al. Nonparallel geographic patterns for tolerance to cold and desiccation in, De Camargo R, Phaff HJ. [3] Generations hatched early in the year have shorter lifespans than generations hatched after September. The disadvantage of these … Photograph by Martin Hauser, California Department of Food and Agriculture. They can be found in deserts, tropical rainforest, cities, swamps, and alpine zones. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. 2011). [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. 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". Although the major damages are caused by the larvae that soften the cherry by making not marketable s. Although up to 65 adults have been found in the same cherry, only the presence of one of them causes appreciable damage to the fruit. Variation of. RNA interference (RNAi) or double-stranded RNA (dsRNA)-mediated gene silencing is rapidly becoming a widely used functional genomics tool in insects and holds great potential for insect pest control. In Japan, the fly produces 10 to 13 generations (Kanzawa 1939). Pupae of Drosophila spp. Diapause is a form of dormancy used by many insects to survive adverse environmental conditions, which can occur in specific developmental stages in different species. Some of these could easily be confused with Drosophila suzukii due to their spotted wings. 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. Management typically requires killing gravid adult female flies with insecticides to prevent damage resulting from oviposition and larval development. Monitoring and trapping. [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. [8][9], D. suzukii has a slow rate of evolution due to its lower number of generations per year, because it enters winter diapause. Head of an adult spotted-wing drosophila, Drosophilia suzukii (Matsumura), frontal view. Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. Genetics 162: 1-3. Origin. Males have a distinguishing dark spot along the front edge of each wing. 2011). Adult life span is about three to nine weeks. [6] The larvae are small, white, and cylindrical reaching 3.5 millimetres (9⁄64 in) in length.[4]. Toda MJ. The traps perform best when deployed under cool and shady areas in the field (Walsh et al. However, sensitivity to desiccation depends upon climatic conditions and flies could develop desiccation resistance over time (Davidson 1990, Bradley et al. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). Not only are they larger, but they are common and often important agricultural pests (Green 2002). [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. However, Drosophila suzukii's preference for ripening fruit necessitates use of chemicals with shorter pre-harvest intervals (Walsh et al. 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 northern species D. montana is the best cold-adapted, and is primarily found at high altitudes. Some northern species hibernate. A number such as Beauveria bassiana, Isaria fumosorosea, Metarhiziumanisopliae and Lecanicillium lecanii ensure a death rate of more than 50% among fruit flies11,20. [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]. First detected within the continental United States in August 2008, Drosophila suzukii has become a serious threat to fruit crops. [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota in 2012. To prevent resistance to certain sprays, farmers must rotate among different insecticides. These fruit flies are about 1/10-inch-long and have bright red eyes and black horizontal stripes on their abdomens. 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 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. The vast majority of Drosophila flies are associated with rotten or over-ripened fruits and are nuisance pests. Simple funnel trap baited with vinegar to trap adult Drosophila. Drosophila suzukii immatures, and therefore the parasitoid offspring that depend on them, could not survive at a constant average temperature of 29.3 °C. Parasitoids from the families Braconidae and Cynipidae are potential biocontrol agents of Drosophila suzukii. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit.
