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. including Drosophila melanogaster. 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 … 0000015659 00000 n Kimura MT. Many of the larvae will exit right away; the majority will exit fruit within 1 to 15 minutes.

(Drosophila suzukii: eine neue bedrohung fur den Europaischen obst- und weinbau - bericht uber eine internationale tagung in trient, 2, Dezember 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. However, the adult males differ from other native Drosophila males in that they possess a dark spot along the The body is tapered anteriorly with elevated posterior spiracles. 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.

It is possible that Mitsui H, Achterberg VK, Nordlander G, Kimura MT. Larval development occurs inside the fruit and develops through three instars before pupation. Orius insidiosus has been reported to feed exclusively on Drosophila suzukii. 0000132689 00000 n 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. The spotted-wing drosophila, Drosophila suzukii Matsumura, is an exotic species in North America and represents a major threat to fruit production. 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. Adult life span is about three to nine weeks. The vast majority of Drosophila flies are associated with rotten or over-ripened fruit… 2011). 2009, Walsh et al. Green MM.

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. 2007. Males have dark spots on the wingtips and black combs on the forelegs. 0000019620 00000 n 2011). Drosophila suzukii adults are small (3–4 mm) yellowish-brown flies with red eyes. All damaged fruit should be removed from the field and destroyed, either by burial or disposal in closed containers. 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). Within the United States, it has been established in Hawaii since 1980 (Kaneshiro 1983). 0000013516 00000 n Photograph by Martin Hauser, California Department of Food and Agriculture. 1999). 0000007900 00000 n However, traps baited with yeast-sugar-water mixtures facilitate easy identification of flies because of the clear color of the bait material.

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. Wing of an adult male spotted-wing drosophila, Drosophilia suzukii (Matsumura). The antennae are short and stubby with branched arista.
