Unlike other Drosophila,female D. suzukiipossess a serrated ovipositor that enables them to cut through the skin of ripening fruit, and subsequent … Larval development occurs inside the fruit and develops through three instars before pupation. [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. Adult life span is about three to nine weeks. strain UCD-D_suzukii, the first member of this genus to be sequenced. Pupae of Drosophila spp. Farmers can also harvest their soft fruit early which reduces the exposure of fruit to D. suzukii and the likelihood of damage. Vertical microdistribution of Drosophilidae (Diptera) within various forests in Hokkaido. Figure 7. The larvae are white and cylindrical, reaching 3.5mm in length. Adaptations to temperate climates and evolution of over-wintering strategies in the. Not only are they larger, but they are common and often important agricultural pests (Green 2002). Yeasts occurring in, Dubuffet A, Colinet D, Anselme C, Dupas S, Carton Y, Poirié M. 2009. 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. 1974 Transmission of. on overripe banana. 2009). The spotted wing Drosophila (Drosophila suzukii) is an invasive and serious economic pest to small and stone fruits and its control is difficult. 2015).The larval feeding in fruits causes softness and fruit dropping (Stacconi et al. 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. Flies could survive up to 10 generations per year under California climate conditions (Walsh et al. Simple funnel trap baited with vinegar to trap adult Drosophila. Ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), lateral view. 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. 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. Chemical control. [43] Yeasts also form an important part of the Drosophila microbiome, with a mutualistic relationships to yeast being described in other Drosophila species. [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. Photograph by Martin Hauser, California Department of Food and Agriculture. Drosophila flies are weak fliers but spread easily through infested fruits or by wind. 2009). [4] The depressions may also exude fluid which may attract infection by secondary bacterial and fungal pathogens. The vast majority of Drosophila flies are associated with rotten or over-ripened fruit… [21] As D. suzukii continues to spread, most of the states will most likely observe it. [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]. Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a fruit fly. 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 species are found all around the world, with more species in the tropical regions. The larvae grow inside the fruit. In 2015 it is estimated that national economic loss for producers in the United States was $700 million. 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 vast majority of Drosophila flies are associated with rotten or over-ripened fruits and are nuisance pests. suzukii. Photograph by Martin Hauser, California Department of Food and Agriculture. [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. Pupation can occur either inside or on the exterior of fruit. [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. Drosophila suzukii is native to East Asia and has spread to Europe, Asia, Africa, the Americas, and Oceania [ 7 ]. 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. [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. This wound can be a point of entry for fungi such as the monilia. In the continental U.S., it was first detected in Santa Cruz County, California, on caneberry and strawberry plants (Bolda et al. [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. Figure 5. are very sensitive to desiccation. Variation of. 1990. Spotless males are also possible, but are rarely observed in the field and should be verified by a taxonomist for positive identification. Drosophilaflies are sometimes called small fruit flies. Spotted wing drosophila: Potential economic impact of a newly established pest. 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. However, traps baited with yeast-sugar-water mixtures facilitate easy identification of flies because of the clear color of the bait material. 2011). 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 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. Adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). Mitsui H, Achterberg VK, Nordlander G, Kimura MT. [44][45][46] The yeast species found to be most frequently associated with D. suzukii were Hanseniaspora uvarum, Metschnikowia pulcherrima, Pichia terricola, and P. The fruit fly D. suzukii is a fruit crop pest and is a serious economic threat to soft summer fruit. The females have a serrated ovipositor with which they penetrate the fruit skin. The flies are most active at 20°C (68°F). Adults are able to withstand longer periods of cold conditions than larvae or pupae (Walsh et al. on overripe banana. Good field sanitation is critical to prevent further spread of flies. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. Females will oviposit on many fruits and in regions of scarce fruit, many females will oviposit on the same fruit. Figure 11. insidiosus. 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. 2006, Walsh et al. A female lays approximately one to three eggs per oviposition site. Biological control. There are different types of traps, both commercial and home-made, that are effective in monitoring it. First detected within the continental United States in August 2008, Drosophila suzukii has become a serious threat to fruit crops. A polyphagous pest, it infests a wide range of fruit crops, included grape, as well as an increasing number of wild fruits. [17] In Fall 2010 the fly was also discovered in Michigan[18] and Wisconsin. A female may lay as many as 300 eggs during its lifespan. Here we present the draft genome of Tatumella sp. Only adults overwinter successfully in the research conducted thus far. [30], Earwigs,[39] damsel bugs,[39] spiders,[39] ants,[39] and Orius ("minute pirate bugs")[39] especially O. [24] Future losses may decrease as growers learn how to better control the pest, or may keep increasing as the fly continues to spread. Photograph by Martin Hauser, California Department of Food and Agriculture. [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. Ministry of Agriculture and Lands, British Columbia. The oviposition site is visible in many fruit by a small pore scar in the skin of the fruit often called a "sting". [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. The eggs are laid singly and are randomly distributed on fruits. 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. Figure 12. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Drosophila suzukii is a severe economic invasive pest of soft-skinned fruit crops. 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. 2011). Varietal differences in survivorship could have resulted from nutritional factors, grape mass (g), or a combination of both which may have been … 2010). Nonparallel geographic patterns for tolerance to cold and desiccation in, De Camargo R, Phaff HJ. 1957. Like most Drosophila spp., reproduction in Drosophila suzukii is rapid. Photograph by Martin Hauser, California Department of Food and Agriculture. 2010). 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. Drosophila suzukii is an invasive plague native to Southeast Asia that has colonized several countries in America and most European countries. The pest has also been found in Europe, including the countries of Belgium, Italy, France, and Spain.[22][23]. Multiple clutches of larvae may be present on the same fruit because females may oviposit on the same fruit (Kanzawa 1939, Mitsui et al. (December 2009). All damaged fruit should be removed from the field and destroyed, either by burial or disposal in closed containers. The research was conducted in collaboration with the U.S. Department of Agriculture, Agricultural Research Service, Horticulture Crops Bolda, M. P., Goodhue, R. E. & Zalom, F. G. Spotted wing drosophila: potential economic impact of a newly established pest. Orius insidiosus has been reported to feed exclusively on Drosophila suzukii. The adult female of Drosophila melanogaster (our beloved model organism), lays her eggs on overripe or rotting fruits. In addition, it alsoreduces the fertility of the flies (during these ten days), resulting in feweroffspring20. Wing of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). 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. Photograph by Martin Hauser, California Department of Food and Agriculture. [26], In areas where D. suzukii has already been established or where its activity has been monitored, there are different ways to control it. Management typically requires killing gravid adult female flies with insecticides to prevent damage resulting from oviposition and larval development. [10], Native to southeast Asia, D. suzukii was first described in 1931 by Matsumura. Infested fruit collapse around the feeding site very rapidly and rot due to mold or secondary infections (Beers et al. Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. 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. Damage is caused primarily by larvae feeding on fruit pulp turning the fruit flesh brown and soft. Therefore, all nearby sources of fruit should be managed to eliminate flies (Ministry of Agriculture and Lands, British Columbia 2009). The species is endemic in Asia. 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. Larvae: The larvae are milky-white and cylindrical with black mouthparts.

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. [42] This fly is also infected with a variety of viruses in the wild. The total life cycle may be completed within one to two weeks depending upon the climatic conditions (Kanzawa 1939). The males have a dark spot near to the edge of each wing, which gives the species its common name. 2011). Beers EH, Smith TJ, Walsh DB. In Japan, the fly produces 10 to 13 generations (Kanzawa 1939). In general, Drosphila spp. 2011). (Enterobacteriaceae). Drosophila made their way to the Hawaiian Islands and radiated into over 800 species. Figure 3. Physiological responses to selection for desiccation resistance in, Bolda MP, Goodhue RE, Zalom FG. The effect of entomopathogenic fungi on Drosophila suzukii larvae, pupae andadult flies is currently being fully tested. The traps perform best when deployed under cool and shady areas in the field (Walsh et al. Adults emerge from overwintering when temperatures reach approximately 10 °C (50 °F) (and 268 degree days). As a result of its willingness to explore and test novel fruit species, it has become extremely polyphagous. However, flies emerging late in the season overwinter and may live longer. Photograph by Martin Hauser, California Department of Food and Agriculture. 2011). The female has a long, sharp, serrated ovipositor. Within the United States, it has been established in Hawaii since 1980 (Kaneshiro 1983). This species, whose development is very dependent on temperature and high relative humidity, can attack a very wide range of cultivated and wild fruits. The northern species D. montana is the best cold-adapted, and is primarily found at high altitudes. Many of the larvae will exit right away; the majority will exit fruit within 1 to 15 minutes. (February 2010). After 1 or 2 days, the area around the "sting" softens and depresses creating an increasingly visible blemish. Management practices for spotted-wing drosophila are similar to those used to manage common Drosophila flies. 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 disadvantage of these … Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. Figure 9. … Green MM. Kanzawa. First instar larvae are approximately 0.07 mm in length. b) Count larvae immediately—before they die and possibly sink to bottom of tray. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. Photograph by Martin Hauser, California Department of Food and Agriculture. The initial oviposition site becomes sunken. 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. 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). Animal and Plant Health Inspection Service, North American Plant Protection Organization, Walsh, D. Press Release, Washington State University. It attacks a range of soft skinned fruit and reduces crop yield and quality through direct feeding damage and secondary infection of the fruit. Pupae: The pupae are cylindrical, reddish brown with two small projections at the end. Figure 6. Cultural control. [3] By the 1980s, the "fruit fly" with the spotted wings was seen in Hawaii. Most types of sprays need to be applied each week, at a minimum. 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. 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. They can be found in deserts, tropical rainforest, cities, swamps, and alpine zones. The Metarhizium Brunneum fungus even causesa death of nearly 90% of fruit flies after ten days. The egg, larval and pupal stages last from 1–3, 3–13, and 4–5 days, respectively (Kanzawa 1939). 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. This strain was isolated from Drosophila suzukii larvae as part of a larger project to study the microbiota of D. suzukii . In addition, males have two rows of combs on each fore tarsus which are absent in females. 2011). [12] Larvae may leave the fruit, or remain inside it, to pupate. Bradley TJ, Williams AE, Rose MR. 1999. Males have dark spots on the wingtips and black combs on the forelegs. 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. kluyveri. Drosophila suzukii immatures, and therefore the parasitoid offspring that depend on them, could not survive at a constant average temperature of 29.3 °C. [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 spotted wing Drosophila (Drosophila suzukii) is from East Asia and then became established in Hawaii. Eggs: The eggs are translucent, milky-white, and glossy. Spotless males are also possible, but are rarely observed in the field. 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. 2013; Ioriatti et al. However, the role of beneficial organisms in management of Drosophila suzukii has not been fully ascertained (Walsh et al. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. 1988. Mature larvae may grow up to 6 mm in length (Kanzawa 1939, Walsh et al. The lifespan of D. suzukii varies greatly between generations; from a few weeks to ten months. The larger larvae cut breathing holes in fruit. Most species breed in various kinds of decaying plant and fungal material, including fruit, bark, slime fluxes, flowers, and mush… The foreleg of the male sports dark bands on the first and second tarsi. 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. The telltale spots on the wings of male D. suzukii have earned it the common name "spotted wing drosophila" (SWD). Larvae of Drosophila spp. [14] During the summer of 2010 the fly was discovered for the first time in South Carolina, North Carolina,[15] Louisiana,[16] and Utah. SEM of an ovipositor of an adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura), lateral view. We propose that the microbiome is an important dimension of the ecological interactions between Drosophila species. The antennae are short and stubby with branched arista. [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. Adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura). Some of these could easily be confused with Drosophila suzukii due to their spotted wings. 1999). Figure 8. Males have dark spots on the wingtips and black combs on the forelegs. 2011). The foreleg of the male sports dark bands on the first and second tarsi. The genome contains 3,602,931 bp in 72 scaffolds. Whilst sharing some natural viruses with its close relative D. melanogaster, D. suzukii also harbours a number of unique viruses specific to it alone. Head of an adult spotted-wing drosophila, Drosophilia suzukii (Matsumura), frontal view. Photograph by Martin Hauser, California Department of Food and Agriculture. Drosophila suzukii adults are small (3–4 mm) yellowish-brown flies with red eyes. Walsh DB, Bolda MP, Goodhue RE, Dreves AJ, Lee J, Bruck DJ, Walton VM, O'Neal SD, Frank GZ. It really is not a fruit fly. The adults have a pale brown or yellowish-brown thorax with black bands on the abdomen. Economic losses have now been reported across North America and in Europe as the fly has spread to new areas. Internal organs of larvae are visible after it has consumed some fruit. 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. & nbsp; The eggs develop and hatch within the fruit in which they are laid (Walsh et al. 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. 2011). The invasive vinegar fly Drosophila suzukiiMatsumura has become a serious pest of soft-skinned fruit globally. To prevent resistance to certain sprays, farmers must rotate among different insecticides. 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. The larvae hatch and grow in the fruit, destroying the fruit's commercial value. Agriculture and Resource Economics Update. 2011). 2011). [27], Farmers have the option of both conventional and organic sprays [28] to control D. suzukii. A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. Economic impacts are significant; losses from large scale infestation (20% loss) across the US alone could equate to farm gate impacts > $500M. Steck GJ, Dixon W, Dean D. (August 2009). Origin. 2007. 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. Its body is yellow to brown with darker bands on the abdomen and it has red eyes. Photograph by Whitney Cranshaw, Colorado State University, Bugwood.org. Different laws and pre-harvest date intervals need to be kept in mind when choosing a type of spray. (no longer available online), Davidson JK. However, true fruit flies belong to the family Tephritidae. Traps that use apple cider vinegar with a whole wheat dough bait have been successful for farmers to both capture and monitor D. Regularly stir the solution to bring larvae to the surface and to break Drosophila suzukii 1987. Translated from Japanese by Shinji Kawaii. [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. (August 2010). Adults: Florida is home to at least 27 addiional Drosophila spp. 2011). Not only are they larger, but they are common and often important agricultural pests (Green 2002). Males have a distinguishing dark spot along the front edge of each wing. Kimura MT. European and Mediterranean Plant Protection Organization. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. They are approximately 2–3 mm long. Photograph by Martin Hauser, California Department of Food and Agriculture. 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. Figure 4. Some northern species hibernate. 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. 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. SEM of genitalia of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). Timing of the sprays is important to effectively controlling it. Activity becomes reduced at temperatures above 30°C (86°F) or below freezing. 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. 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. The body is tapered anteriorly with elevated posterior spiracles. Since D. suzukii is more active in the morning and evening those are the best times to control it. There are approximately 1,500 known species in the genus Drosophila (Markow and O'Grady 2006). Oviposition scars from a female spotted-wing drosophila, Drosophilia suzukii (Matsumura), on a cherry fruit. 2011). 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 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. Drosophila suzukii; SWD) larval infestation. In captivity in Japan, research shows up to 13 generations of D. suzukii may hatch per season. (Kanzawa 1939, Dubuffett et al. However, Drosophila suzukii's preference for ripening fruit necessitates use of chemicals with shorter pre-harvest intervals (Walsh et al. 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. This procedure emerged as the most reliable of several methods tested at Oregon State University. Toda MJ. These fruit flies are about 1/10-inch-long and have bright red eyes and black horizontal stripes on their abdomens. Due to the impact of D. suzukii on soft fruits, farmers have started to monitor and control it. Drosophila suzukii is a serious economic pest and we determined the conditions for adult reproductive diapause by the females in our previous studies. 2011.
