The total life cycle may be completed within one to two weeks depending upon the climatic conditions (Kanzawa 1939). Photograph by Martin Hauser, California Department of Food and Agriculture. The spotted wing Drosophila (Drosophila suzukii) is an invasive and serious economic pest to small and stone fruits and its control is difficult.

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.

In the continental U.S., it was first detected in Santa Cruz County, California, on caneberry and strawberry plants (Bolda et al. Activity becomes reduced at temperatures above 30°C (86°F) or below freezing. However, Drosophila suzukii's preference for ripening fruit necessitates use of chemicals with shorter pre-harvest intervals (Walsh et al. Green MM. 0000047936 00000 n 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. A single female can lay one to 60 eggs per day and 200–600 eggs in her lifetime. (February 2010). Good field sanitation is critical to prevent further spread of flies. 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. Abstract. 0000003077 00000 n 2011). 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. Adult life span is about three to nine weeks. Adult females of Drosophila Suzukii damage the surface of the cherry during laying. Adults are able to withstand longer periods of cold conditions than larvae or pupae (Walsh et al. 2010). Some of these could easily be confused with Drosophila suzukii due to their spotted wings. Therefore, all nearby sources of fruit should be managed to eliminate flies (Ministry of Agriculture and Lands, British Columbia 2009). 0000006649 00000 n Figure 8. The spotted-wing drosophila, Drosophila suzukii Matsumura, is an exotic species in North America and represents a major threat to fruit production. The egg, larval and pupal stages last from 1–3, 3–13, and 4–5 days, respectively (Kanzawa 1939). 0000002521 00000 n Ripe fruit should be picked frequently to minimize population buildup. 0000017148 00000 n Larval development occurs inside the fruit and develops through three instars before pupation. 0000131844 00000 n The vast majority of Drosophila flies are associated with rotten or over-ripened fruit… Adult female spotted-wing drosophila, Drosophilia suzukii (Matsumura).
