Drosophila suzukii
spotted wing drosophila, SWD, spotted-winged drosophila, cherry vinegar fly
Drosophila suzukii, commonly called the spotted wing drosophila or SWD, is a small vinegar fly native to Southeast Asia that has become a major invasive pest of soft-skinned fruits in North America, Europe, and other regions. Unlike most Drosophila species that infest rotting fruit, females use their serrated ovipositor to lay eggs in intact, ripening fruit, causing significant economic damage to crops including cherries, blueberries, raspberries, blackberries, and grapes. First described in 1931 and observed in Japan as early as 1916, the species was detected in Hawaii in the 1980s and subsequently invaded continental North America in 2008 and Europe shortly thereafter, spreading rapidly due to its high reproductive potential and polyphagous nature.
Rhagoletis cingulata
Eastern Cherry Fruit Fly, North American Cherry Fruit Fly, Cherry Fruit Fly
Rhagoletis cingulata, commonly known as the eastern cherry fruit fly, is a tephritid fruit fly species native to North America and introduced to Europe. It is a significant agricultural pest of cultivated and wild cherry species (Prunus spp.), particularly sweet cherry (P. avium) and sour cherry (P. cerasus). Females oviposit into ripening fruit, and larvae develop within the pulp, causing direct crop damage. The species exhibits latitudinal variation in morphology and phenology, with European populations appearing later in the season than the native European cherry fruit fly (R. cerasi).
