A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. The adult female of Drosophila melanogaster (our beloved model organism), lays her eggs on overripe or rotting fruits. A large number of Drosophila species are known from Australia and many Drosophila species have larvae that are commonly found in rotting fruit. Monitor adult fly populations before fruit begin ripening and before flies begin laying eggs. Small white larvae hatch from eggs within a few days and feed inside the fruit, causing it to soften and collapse around the feeding site. 2006, Walsh et al. 2002.

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. However, true fruit flies belong to the family Tephritidae.

Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), is an invasive pest of soft- and stone-fruit, which has become established throughout temperate regions of the world in the last decade. Adult life span is about three to nine weeks. Entomopathogenic nematodes have been proposed as biological agents for the control of Drosophila suzukii, an invasive pest of small-stone and soft-skinned fruits.Larvae of the fly are susceptible to Steinernema carpocapsae infection but the reaction of immune defenses of the host are unknown. hÞb```b`àxÀÀÆÀÀ?‹Abì,G&¹(¨0ù&¨ã$`–.,á*9Åêè†ÅB u³R§Eߞ€ðq™D4éPŠx}ƒ®¥Þ›ƒÕfÍΑ Tç¸Äå®T„Á. are very sensitive to desiccation. 0000045287 00000 n 0000006535 00000 n 0000118418 00000 n 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. 0000131567 00000 n 0000007566 00000 n 0000014490 00000 n 0000014989 00000 n 0000131121 00000 n However, true fruit flies belong to the family Tephritidae. 0000115043 00000 n & nbsp; 0000025586 00000 n However, flies emerging late in the season overwinter and may live longer. 0000132166 00000 n Figure 9.

Photograph by Martin Hauser, California Department of Food and Agriculture. Parasitoids from the families Braconidae and Cynipidae are potential biocontrol agents of Drosophila suzukii. The egg, larval and pupal stages last from 1–3, 3–13, and 4–5 days, respectively (Kanzawa 1939). The spotted wing Drosophila is a vinegar fly originating from South-East Asia which has invaded many countries in America, Asia and Europe. 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.

Further inquiry, including systematic comparisons of Drosophila larval yeast associations more broadly, will be necessary to understand patterns of microbial resource use in larvae of D. suzukii and other frugivorous species.

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. 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. This species is included in the EPPO A2 List as recommended to be included amongst the species in phytosanitary quarantine. The effect of entomopathogenic fungi on Drosophila suzukii larvae, pupae andadult flies is currently being fully tested. 2011). The Tomakomai Experiment Forest, Hokkaido University. 2011. Under conditions favorable to the SWD, the fruit begin to collapse as quickly as two days after the eggs were laid. However, a few species such as the spotted-wing drosophila, Drosophila suzukii (Matsumura), can infest un-ripened fruits and are of economic significance. Steck GJ, Dixon W, Dean D. (August 2009).

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. 2011). Drosophila or pomace flies are small insects commonly found in association with over-ripened or rotten fruits and vegetables. 2010). Walsh DB, Bolda MP, Goodhue RE, Dreves AJ, Lee J, Bruck DJ, Walton VM, O'Neal SD, Frank GZ. 44: 611-632. In the continental U.S., it was first detected in Santa Cruz County, California, on caneberry and strawberry plants (Bolda et al. (February 2010).

Bucket-style traps or quart containers used for monitoring other Drosophila flies can be effectively used for monitoring Drosophila suzukii. It attacks a range of soft skinned fruit and reduces crop yield and quality through direct feeding damage and secondary infection of the fruit. The vast majority of Drosophila flies are associated with rotten or over-ripened fruit… Larval development occurs inside the fruit and develops through three instars before pupation. 0000049415 00000 n Photograph by Martin Hauser, California Department of Food and Agriculture. 0000020597 00000 n Drosophila flies are sometimes called small fruit flies.

Figure 8. Adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura). Drosophila spp., are rarely able to develop successfully in D. suzukii larvae, partly because of the strong host immune response of the fly larvae (Chabert, Allemand, Poyet, Eslin, & Gibert, 2012; Gabarra European and Mediterranean Plant Protection Organization.

Therefore, all nearby sources of fruit should be managed to eliminate flies (Ministry of Agriculture and Lands, British Columbia 2009). Larvae: The larvae are milky-white and cylindrical with black mouthparts. Some of these could easily be confused with Drosophila suzukii due to their spotted wings. Molecular analysis of the larvae confir-med that larvae belong to the Drosophila suzukii. SWD belong to the Sophophora subgenus of Drosophila, a group that contains a large number of species (>300 worldwide), including the common cosmopolitan D. melanogaster and D. simulans .

Figure1a. 0000017631 00000 n Proportion of ovipositing females (POF ) proportion of parasitoid females that oviposited when exposed to larvae of Drosophila suzukii in artificial diet or blueberries. Figure 7. 2011). These fruits are full of yeasts and have a high protein content.The larvae then develop and grow on a proteinic diet. A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. The adult female of Drosophila melanogaster (our beloved model organism), lays her eggs on overripe or rotting fruits. A large number of Drosophila species are known from Australia and many Drosophila species have larvae that are commonly found in rotting fruit. Monitor adult fly populations before fruit begin ripening and before flies begin laying eggs. Small white larvae hatch from eggs within a few days and feed inside the fruit, causing it to soften and collapse around the feeding site. 2006, Walsh et al. 2002. Multiple clutches of larvae may be present on the same fruit because females may oviposit on the same fruit (Kanzawa 1939, Mitsui 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.

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.
