Evolution of Multiple Sensory Systems Drives Novel Egg-Laying Behavior in the Fruit Pest Drosophila suzukii Highlights d The pest Drosophila suzukii prefers to lay eggs on ripening fruit d Closely related Drosophila species prefer to lay eggs on rotten fruit d Female ﬂies use chemosensation and mechanosensation to choose an oviposition site The larva still develop… Ordinary fruit flies lay their eggs on damaged, overripe or decaying fruit. 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. Netten kunnen goed helpen tegen deze fruitvlieg, maar we zoeken ook naar andere methoden om fruittelers te helpen in hun strijd tegen deze exoot. Drosophila suzukii. The population of Drosophila Suzukii grows rapidly as soon as cherries and other summer fruits start to ripen. Drosophila suzukii The Spotted Wing Drosophila (SWD), Drosophila suzukii (Matsumura), is a pest of soft fruit native to Asia, but has become established in the Pacific Northwest starting in 2009. Overwinterende vliegen zijn wat donkerder dan de in de zomer aanwezige exemplaren. Suzukii Drosophila: a new threat feature for the European fruit and viticulture - report for the international conference in Trient, 2, December 2011. Wilt u met ons samenwerken? Drosophila suzukii is a vinegar fly that looks similar to drosophila melanogaster. The foreleg of the male sports dark bands on the first and second tarsi. Fig. 2011). De suzuki-fruitvlieg veroorzaakt schade in onder meer aardbeien, blauwe bessen, frambozen, bramen, kersen en pruimen. In contrast, Drosophila Suzukii females can use their serrated ovipositor to lay their eggs in fruit that is still ripening and is undamaged. Unexpectedly, females fed E+S had more ovarial eggs than sucrose-fed females, suggesting that erythritol might inhibit D. suzukii laying eggs. Netten kunnen goed helpen tegen deze fruitvlieg, maar we zoeken ook naar andere methoden om fruittelers te helpen in hun strijd tegen deze exoot. This behaviour is allowed by an enlarged and serrated ovipositor that can pierce intact fruit skin. There are different types of parasitic wasps, and they all lay their eggs in a Drosophila larva or pupa. Onder gunstige omstandigheden kan een vrouwtje honderden eieren leggen en bij 20°C duurt een generatie 16 dagen. 420 Diagnostics The female has a long, sharp, serrated ovipositor. Klik op de foto voor een groter exemplaar. Larval consumption and the associated microbial infection cause rapid fruit degradation, thus drastic yield and economic loss. In België werd deze bijzonder schadelijke fruitvlieg voor het Er kunnen zich tot zeven generaties in een seizoen ontwikkelen.Wat kunnen fruitttelers tegen de suzuki-fruitvlieg doen? Our second study examined the effects of diet on fecundity and egg load of female D. suzukii. Drosophila suzukii is an invasive agricultural pest species that lays eggs in fruit during ripening, while most closely related Drosophila species use rotten matter as oviposition substrates. Whereas other species of Drosophila utilize fruit that is decaying, suzukii penetrate fruit that is still on the vine, like peaches, strawberries, cherries, pears, raspberries, nectarines, and particularly in our area, NJ blueberries. An overview of the species can be found in the publication, A detailed overview of the life of Drosophila Suzukii in the spring can be found in the publication. However, the adult males differ from other native Drosophila males in that they possess a dark spot along the De suzuki-fruitvlieg (Drosophila suzukii) is een invasieve fruitvlieg die steeds vaker voorkomt in Europa en grote schade kan aanrichten in de fruitteelt. 12 Drosophila suzukii – eggs. Adults are 2 to 3 mm long with red eyes, a yellow-brown thorax, and black stripes on the abdomen. Project Overview So, what’s the problem. The male has a distinct dark spot near the tip of each wing; females do not have the spotted wing. Drosophila Suzukii - how can fruit growers cope with this pest? Drosophila suzukii (Matsumura), also known as spotted-wing drosophila, is an economic pest of soft-skinned and stone fruit (Bolda et al. Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) native to South East Asia is one of the most important invasive pests of unripe fruits which invaded European countries from 2008. Suzuki's fruitvlieg of Aziatische fruitvlieg (Drosophila suzukii) is een vliegensoort uit de familie van de fruitvliegen (Drosophilidae).De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1931 door Matsumara. Problem: Spotted Wing Drosphila - Drosophila suzukii Hosts: Blackberries, blueberries, boysenberries, raspberries, strawberries and grapes. Nets can help prevent damage, but we are also looking for other methods to help fruit growers in their fight against this exotic species. Please contact: Non-crop plants used as hosts by Drosophila suzukii in Europe, Overwintered Drosophila suzukii are the main source for infestations of the first fruit crops of the season. This species is included in the EPPO A2 List as recommended to be included amongst the species in phytosanitary quarantine. Most Drosophila species are attracted to overripe and rotting fruit for ovipositing sites, but SWD females have saw-like ovipositors which they use to lay eggs in ripening fruit, still on the plant. Drosophila Suzukii can use a large number of plant species as hosts. That is important as chemical agents barely have any effect on Drosophila suzukii. Indeed, in a recent study where we compared the egg-laying preferences of different Drosophila species for different substrates (Karageorgi et al., 2017), we found that D. melanogaster shared the preference of a large number of other species for rotten fruits and soft substrates, while D. suzukii radically chose to lay on ripe or even unripe fruits, and tolerated much harder substrates. Its relatively large, sclerotized, and serrated ovipositor enables the ability to penetrate ripening fruits, providing a protected environment for its egg and larval stages. Description: The spotted wing drosophila resembles other native vinegar and fruit flies. 2010).Unlike other Drosophilidae which target overripe fruit, D. suzukii possess a serrated ovipositor which they use to pierce and oviposit into ripe, marketable fruit (Walsh et al. Ordinary fruit flies lay their eggs on damaged, overripe or decaying fruit. At the same time, this fruit fly represents an increasing threat to various fruit crops throughout Europe. The only natural enemy that did have an effect on the development of the Drosophila population was the parasitic wasp. Journal fur Kulturpflanzen, 64:68-72 Why is Drosophila Suzukii more harmful than ordinary fruit flies? Verschillende soorten sluipwespen parasiteren de larven of poppen van de suzuki-fruitvlieg en kunnen zo een bijdrage leveren aan de bestrijding. These can be seen with a magnifying glass. Abstract. Fly Drosophila suzukii male (left) and female (right) [/ caption] The adults of this insect are flies with a size of 2-3mm, light yellowish-brown thorax, red eyes and abdomen with black bands. After all, in contrast with other fruit flies, Drosophila suzukii lays its eggs in both ripe and unripe fruit. Mixtures of yeast, sugar, and water; fruit purees, distillates from apple cider vinegar or wine; ethanol, acetic acid, and phenylethanol in 1: 22: 5 rat… (Drosophila suzukii: eine neue bedrohung fur den Europaischen obst- und weinbau - bericht uber eine internationale tagung in trient, 2, Dezember 2011.) The males have a few striking dark spots on their wings, from which the species draws its English name: Spotted Wing Drosophila. The spotted wing Drosophila is a vinegar fly originating from South-East Asia which has invaded many countries in America, Asia and Europe. Volwassen suzuki-fruitvliegen hebben het typische uiterlijk van de fruitvlieg: ze zijn 2-3 mm lang, met rode ogen en een lichtbruin achterlijf met zwarte strepen. A D. suzukii male (A) is characterised by its spotted wings, while females (B) possess a saw-like ovipositor which enables them to break the relatively hard skin of fresh ripening fruits and lay eggs in it. Nadat de eieren zijn gelegd, steken twee luchtpijpjes (filamenten) door de schil naar buiten. DROSOPHILA SUZUKII: A NEW INVASIVE SPECIES THREATENING EUROPEAN FRUIT PRODUCTION It lays its eggs and feeds on unwounded ripening fruits of many plant species: Drosophila suzukii is a pest endemic to South East Asia able to threaten the fruit industry worldwide. Like other members of the Drosophilidae, D. suzukii is small, approximately 2 to 3.5 mm in length and 5 to 6.5 mm in wingspan and looks like its fruit and vinegar fly relatives. In fact, it can attack and develop in over 150 wild and cultivated fruits as well as in fruits of ornamental plants. Adult Drosophila Suzukii have the typical appearance of fruit flies: they are 2-3 mm long, with red eyes and a light brown abdomen with black stripes.
