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.
Eutorna phaulocosma
False raspberry bud moth, Blackberry budmoth
Eutorna phaulocosma is a small depressariid moth native to Australia and New Zealand. Adults have been described with a wingspan of about 15–16 mm and mottled brown forewings. In New Zealand boysenberry gardens, its caterpillars fed on leaves, damaged flower buds, and entered young fruit. That crop association also makes the moth useful in studies of berry pests and their parasitoids.
