[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. 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. Multiple clutches of larvae may be present on the same fruit because females may oviposit on the same fruit (Kanzawa 1939, Mitsui et al. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. The fruit fly D. suzukii is a fruit crop pest and is a serious economic threat to soft summer fruit. Larvae: The larvae are milky-white and cylindrical with black mouthparts. Photograph by Martin Hauser, California Department of Food and Agriculture. on overripe banana. (February 2010). However, a few species such as the spotted-wing drosophila, Drosophila suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. One way to manage D. suzukii is to remove the infested fruit and place it in a plastic bag in the garbage. Cultural control. Management practices for spotted-wing drosophila are similar to those used to manage common Drosophila flies. After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. This procedure emerged as the most reliable of several methods tested at Oregon State University. All damaged fruit should be removed from the field and destroyed, either by burial or disposal in closed containers. [27], Farmers have the option of both conventional and organic sprays [28] to control D. suzukii. Drosophila suzukii is an invasive and economically important pest of many soft-skinned fruits such as blueberries, blackberries, raspberries, strawberries, cherries, and other fruits. 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. Drosophila suzukii larval survivorship to adulthood was significantly reduced in the presence of Z. indianus in Petit Manseng, Petit Verdot, and Cabernet Franc for all interspecific densities tested compared with the intraspecific D. suzukii controls. 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. Timing of the sprays is important to effectively controlling it. Wing of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). & nbsp; There are approximately 1,500 known species in the genus Drosophila (Markow and O'Grady 2006). The egg, larval and pupal stages last from 1–3, 3–13, and 4–5 days, respectively (Kanzawa 1939). 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. Economic losses have now been reported across North America and in Europe as the fly has spread to new areas. The genome contains 3,602,931 bp in 72 scaffolds. The female has a long, sharp, serrated ovipositor. Monitor adult fly populations before fruit begin ripening and before flies begin laying eggs. The initial oviposition site becomes sunken. are very sensitive to desiccation. Adult females of Drosophila Suzukii damage the surface of the cherry during laying. [8][9], D. suzukii has a slow rate of evolution due to its lower number of generations per year, because it enters winter diapause. There are different types of traps, both commercial and home-made, that are effective in monitoring it. Figure 3. Drosophila suzukii is a serious economic pest and we determined the conditions for adult reproductive diapause by the females in our previous studies. They can be found in deserts, tropical rainforest, cities, swamps, and alpine zones. Drosophila flies are weak fliers but spread easily through infested fruits or by wind. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. The niches utilized by the fly species partially overlap, as do the microbiota that sustain them, and interactions among these players may drive the … The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Pupae of Drosophila spp. 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. on overripe banana. However, true fruit flies belong to the family Tephritidae. Kanzawa. The effect of entomopathogenic fungi on Drosophila suzukii larvae, pupae andadult flies is currently being fully tested. 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. European and Mediterranean Plant Protection Organization. To prevent resistance to certain sprays, farmers must rotate among different insecticides. [12] Larvae may leave the fruit, or remain inside it, to pupate. Unlike other Drosophila,female D. suzukiipossess a serrated ovipositor that enables them to cut through the skin of ripening fruit, and subsequent … [44][45][46] The yeast species found to be most frequently associated with D. suzukii were Hanseniaspora uvarum, Metschnikowia pulcherrima, Pichia terricola, and P. Figure 6. 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. Since then, it has rapidly spread to new areas including Florida, Louisiana, Michigan, North Carolina, Oregon, South Carolina, Utah, Washington and Wisconsin in the U.S., and British Columbia in Canada (Walsh et al. Mitsui H, Achterberg VK, Nordlander G, Kimura MT. The research was conducted in collaboration with the U.S. Department of Agriculture, Agricultural Research Service, Horticulture Crops 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. Photograph by Martin Hauser, California Department of Food and Agriculture. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. [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. These fruits are full of yeasts and have a high protein content.The larvae then develop and grow on a proteinic diet. 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. including Drosophila melanogaster. 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. 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. They are approximately 2–3 mm long. Therefore, expert examination by a specialist is needed for positive identification and confirmation (Steck et al. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. The adult female of Drosophila melanogaster (our beloved model organism), lays her eggs on overripe or rotting fruits. Larval development occurs inside the fruit and develops through three instars before pupation. The vast majority of Drosophila flies are associated with rotten or over-ripened fruit… Since D. suzukii is more active in the morning and evening those are the best times to control it. The serrations are much darker than the rest of ovipositor (Kanzawa 1939, Walsh et al. Ripe fruit should be picked frequently to minimize population buildup. [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. There are approximately 1,500 known species in the genus Drosophila (Markow and O'Grady 2006). [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. In this project we are focusing on finding natural enemies (parasitoids) of the pest to introduce into Europe. 2011. Figure 10. A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. Photograph by Martin Hauser, California Department of Food and Agriculture. Figure 4. This wound can be a point of entry for fungi such as the monilia. Ministry of Agriculture and Lands, British Columbia. … [4] Research investigating the specific threat D. suzukii poses to these fruit is ongoing. Photograph by Martin Hauser, California Department of Food and Agriculture. Chemical control. However, true fruit flies belong to the family Tephritidae. This method is effective from removing D. suzukii from gardens and small areas but is difficult for farmers with larger operations to do this. 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. 2015).The larval feeding in fruits causes softness and fruit dropping (Stacconi et al. Overall, we found that microbes isolated from D. suzukii promote D. melanogaster larval development, which is consistent with the model that infestation of fruit by D. suzukii can open up habitat for D. melanogaster. Therefore, all nearby sources of fruit should be managed to eliminate flies (Ministry of Agriculture and Lands, British Columbia 2009). 2011). Biological control. 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. 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 … [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. Figure 8. Insecticide sprays effective against other Drosophila flies are also effective against Drosophila suzukii adults. Drosophila flies are sometimes called small fruit flies. Research Bulletin of College Experiment Forests. [19] The fly was first discovered in the northeastern states in 2011[20] and in Minnesota in 2012. Degree-day models on Drosophila suzukii suggest that the entire life cycle (egg to egg laying female) can be completed within 12 to 15 days at 18.3°C (65°F) or a little more than a week at 21.1°C (70°F) (Walsh et al. 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 lifespan of D. suzukii varies greatly between generations; from a few weeks to ten months. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. It was first recorded as invasive in Hawaii in 1980 and then simultaneously in California and in Europe in 2008. It really is not a fruit fly. Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. 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. Figure 12. A number such as Beauveria bassiana, Isaria fumosorosea, Metarhiziumanisopliae and Lecanicillium lecanii ensure a death rate of more than 50% among fruit flies11,20. Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. Drosophila suzukii immatures, and therefore the parasitoid offspring that depend on them, could not survive at a constant average temperature of 29.3 °C. Drosophila suzukii adults are small (3–4 mm) yellowish-brown flies with red eyes. Drosophilaflies are sometimes called small fruit flies. 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. (Kanzawa 1939, Dubuffett et al. III. Mixtures of yeast, sugar, and water; fruit purees, distillates from apple cider vinegar or wine; ethanol, acetic acid, and phenylethanol in 1: 22: 5 ratios are potent baits for monitoring Drosophila suzukii populations. As a result of its willingness to explore and test novel fruit species, it has become extremely polyphagous. 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. kluyveri. [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. Beers EH, Smith TJ, Walsh DB. Adults are able to withstand longer periods of cold conditions than larvae or pupae (Walsh et al. insidiosus. Photograph by Martin Hauser, California Department of Food and Agriculture. (Enterobacteriaceae). The spotted wing Drosophila (Drosophila suzukii) is from East Asia and then became established in Hawaii. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. Adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). 2002. "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. 2010). 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. Monitoring and trapping. Photograph by Martin Hauser, California Department of Food and Agriculture. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). 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). SEM of genitalia of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). [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. The eggs develop and hatch within the fruit in which they are laid (Walsh et al. Adaptations to temperate climates and evolution of over-wintering strategies in the. Adults: Florida is home to at least 27 addiional Drosophila spp. 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. Flies could survive up to 10 generations per year under California climate conditions (Walsh et al. Photograph by Martin Hauser, California Department of Food and Agriculture. 1990. Translated from Japanese by Shinji Kawaii. It may be possible to determine if a Virginia vineyard is at risk of D. suzukiiinfestation by analyzing the biotic and abiotic factors around each vineyard. They live for 20-30 days. 2013; Ioriatti et al. 1957. 1974 Transmission of. [42] This fly is also infected with a variety of viruses in the wild. Agriculture and Resource Economics Update. 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. Pupae: The pupae are cylindrical, reddish brown with two small projections at the end. 2011). The body is tapered anteriorly with elevated posterior spiracles. Spotless males are also possible, but are rarely observed in the field and should be verified by a taxonomist for positive identification. A female lays approximately one to three eggs per oviposition site. 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. Mature larvae may grow up to 6 mm in length (Kanzawa 1939, Walsh et al. [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. The species is endemic in Asia. In general, Drosphila spp. 2009, Walsh et al. A polyphagous pest, it infests a wide range of fruit crops, included grape, as well as an increasing number of wild fruits. Males have dark spots on the wingtips and black combs on the forelegs. b) Count larvae immediately—before they die and possibly sink to bottom of tray. However, the role of beneficial organisms in management of Drosophila suzukii has not been fully ascertained (Walsh et al. First instar larvae are approximately 0.07 mm in length. Photograph by Martin Hauser, California Department of Food and Agriculture. The pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. Drosophila or pomace flies are small insects commonly found in association with over-ripened or rotten fruits and vegetables. However, Drosophila suzukii's preference for ripening fruit necessitates use of chemicals with shorter pre-harvest intervals (Walsh et al. The spotted wing Drosophila (Drosophila suzukii) is an invasive and serious economic pest to small and stone fruits and its control is difficult. The females have a serrated ovipositor with which they penetrate the fruit skin. 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). Head of an adult spotted-wing drosophila, Drosophilia suzukii (Matsumura), frontal view. 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. Green MM. 2011). Drosophila suzukii prefers a moderate climate but can also survive in cold conditions (Kanzawa 1939). Spotted wing drosophila: Potential economic impact of a newly established pest. Most types of sprays need to be applied each week, at a minimum. Spotted wing drosophila. Yeasts occurring in, Dubuffet A, Colinet D, Anselme C, Dupas S, Carton Y, Poirié M. 2009. [30], Earwigs,[39] damsel bugs,[39] spiders,[39] ants,[39] and Orius ("minute pirate bugs")[39] especially O. The foreleg of the male sports dark bands on the first and second tarsi. 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. A female may lay as many as 300 eggs during its lifespan. 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. Physiological responses to selection for desiccation resistance in, Bolda MP, Goodhue RE, Zalom FG. suzukii. 2010). 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. Origin. First detected within the continental United States in August 2008, Drosophila suzukii has become a serious threat to fruit crops. [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. However, flies emerging late in the season overwinter and may live longer. (February 2010). The oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". Traps that use apple cider vinegar with a whole wheat dough bait have been successful for farmers to both capture and monitor D. Some of these could easily be confused with Drosophila suzukii due to their spotted wings. Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. Figure 11. Internal organs of larvae are visible after it has consumed some fruit. Bradley TJ, Williams AE, Rose MR. 1999. Drosophila suzukii; SWD) larval infestation. Kimura MT. 2011). Pupation can occur either inside or on the exterior of fruit. 2011). Figure 9. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. These fruit flies are about 1/10-inch-long and have bright red eyes and black horizontal stripes on their abdomens. Spotless males are also possible, but are rarely observed in the field. In addition, it alsoreduces the fertility of the flies (during these ten days), resulting in feweroffspring20. The larvae grow inside the fruit. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. Economic impacts are significant; losses from large scale infestation (20% loss) across the US alone could equate to farm gate impacts > $500M. Toda MJ. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. Figure 5. 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 the continental U.S., it was first detected in Santa Cruz County, California, on caneberry and strawberry plants (Bolda et al. SEM of an ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), lateral view. 44: 611-632. Geographical distributions and host associations of larval parasitoids of frugivorous, Molina JJ, Harisson MD, Brewer JW. 1987. Adult life span is about three to nine weeks. Some northern species hibernate. Males have a distinguishing dark spot along the front edge of each wing. The invasive vinegar fly Drosophila suzukiiMatsumura has become a serious pest of soft-skinned fruit globally. 2011). Like most Drosophila spp., reproduction in Drosophila suzukii is rapid. The larvae are white and cylindrical, reaching 3.5mm in length. The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. Orius insidiosus has been reported to feed exclusively on Drosophila suzukii. Photograph by Martin Hauser, California Department of Food and Agriculture. Drosophila suzukii, like all insects, is host to a variety of microorganisms. The males have a dark spot near to the edge of each wing, which gives the species its common name. [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]. 2009). Variation of. 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. Vertical microdistribution of Drosophilidae (Diptera) within various forests in Hokkaido. The eggs are laid singly and are randomly distributed on fruits. 2007. Parasitoids from the families Braconidae and Cynipidae are potential biocontrol agents of Drosophila suzukii. [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. The larger larvae cut breathing holes in fruit. [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. Abstract Microorganisms play a central role in the biology of vinegar flies such as Drosophila suzukiiand Drosophila melanogaster: serving as a food source to both adults and larvae, and influencing a range of traits including nutrition, behavior, and development. The flies are most active at 20°C (68°F). [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 species are found all around the world, with more species in the tropical regions. Within the United States, it has been established in Hawaii since 1980 (Kaneshiro 1983). Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. Eggs: The eggs are translucent, milky-white, and glossy. In addition, males have two rows of combs on each fore tarsus which are absent in females. 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. 2009). Its body is yellow to brown with darker bands on the abdomen and it has red eyes. strain UCD-D_suzukii, the first member of this genus to be sequenced. [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. In Japan, the fly produces 10 to 13 generations (Kanzawa 1939). The Metarhizium Brunneum fungus even causesa death of nearly 90% of fruit flies after ten days. Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. This strain was isolated from Drosophila suzukii larvae as part of a larger project to study the microbiota of D. suzukii . Good field sanitation is critical to prevent further spread of flies. Genetics 162: 1-3. [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. Laboratory experiments were conducted to determine larval movement of the spotted wing drosophila (Drosophila suzukii Matsumura).Movement of larvae outside of the wild blueberry fruit (Vaccinium angustifolium Aiton) can occur after exhausting fruit food resources pri- or to completion of development or just prior to pupation.We found that when provided a choice larvae select moist … Fruit should be verified by a taxonomist for positive identification the adult spotted-wing...
