In België werd deze bijzonder schadelijke fruitvlieg voor het Nets can help prevent damage, but we are also looking for other methods to help fruit growers in their fight against this exotic species. 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. The females lay their eggs just under the skin of the fruit. 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. A colony of Drosophila melanogaster Meigen was obtained from the INRA Laboratory in Antibes (France). The larva still develop… Abstract. What can fruit growers do to cope with Drosophila Suzukii? - Helaas, uw cookie-instellingen zijn zodanig dat de Video niet getoond kan worden - pas uw permissie voor cookies aan. De vrouwtjes van de suzuki-efruitvlieg daarentegen zijn dankzij een zaagvormige legboor in staat hun eieren te leggen in nog rijpende en onbeschadigde vruchten. Unexpectedly, females fed E+S had more ovarial eggs than sucrose-fed females, suggesting that erythritol might inhibit D. suzukii laying eggs. De suzuki-fruitvlieg (Drosophila suzukii) is een invasieve fruitvlieg die steeds vaker voorkomt in Europa en grote schade kan aanrichten in de fruitteelt. Project Overview So, what’s the problem. Klik op de foto voor een groter exemplaar. Its relatively large, sclerotized, and serrated ovipositor enables the ability to penetrate ripening fruits, providing a protected environment for its egg and larval stages. After all, in contrast with other fruit flies, Drosophila suzukii lays its eggs in both ripe and unripe fruit. At the same time, this fruit fly represents an increasing threat to various fruit crops throughout Europe. The insect resembles common vinegar flies in the genus Drosophila. Drosophila suzukii herkennen en aanpakken : do’s en don’ts De Aziatische fruitvlieg Drosophila suzukii oftewel de ‘suzuki-fruitvlieg’ is in korte tijd het meest gevreesde plaaginsect in de Europese klein/steenfruit- en druiven - teelt geworden. The SWD was first detected in 2008 in the western United States and it has since rapidly spread In fact, it can attack and develop in over 150 wild and cultivated fruits as well as in fruits of ornamental plants. The SWD flies have brownish-yellow thorax, black stripes across the abdomen, and distinct red eyes. 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. It was reared on the same diet Netten kunnen goed helpen tegen deze fruitvlieg, maar we zoeken ook naar andere methoden om fruittelers te helpen in hun strijd tegen deze exoot. Netten kunnen goed helpen tegen deze fruitvlieg, maar we zoeken ook naar andere methoden om fruittelers te helpen in hun strijd tegen deze exoot. To explore the potential of nature to improve the quality of life. By frequently and thoroughly harvesting ripe fruit and removing and destroying rotting fruit, the development of new generations of fruit flies can be prevented. 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. The developing larvae accelerate fruit decay and provide a food source for the adult. Verschillende soorten sluipwespen parasiteren de larven of poppen van de suzuki-fruitvlieg en kunnen zo een bijdrage leveren aan de bestrijding. Een goede hygiëne tijdens de teelt is zeer belangrijk. Only D. suzukii flies laid eggs in the intact region of Thompson grapes (figure 3 b), and these were very rare.Therefore, in order to have enough punctures with eggs to make meaningful comparisons with the punctures without eggs (figure 3 d), we carried out a separate experiment where we placed 6–10 D. suzukii female flies per bottle.We measured the area of a total of 18 randomly … 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. Drosophila suzukii laying an egg in a blueberry Drosophila suzukii laying an egg in a blueberry SPOTTED WING DROSOPHILA (Drosophila suzukii) Although there are native species of fruit or vinegar flies in North America, the spotted wing drosophila (SWD) is a relatively new introduction that damages certain fruit crops throughout the country. 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. 11 Drosophila suzukii - female with strongly sclerotized saw-like ovipositor. 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 However, the adult males differ from other native Drosophila males in that they possess a dark spot along the 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. Here an Monitoring and trapping. Our second study examined the effects of diet on fecundity and egg load of female D. suzukii. D. suzukii females preferred to lay eggs on an atropine-containing medium in the presence of both T. cf. 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… In favourable circumstances, a female can lay hundreds of eggs, and at 20°C a complete generation takes only 16 days.
