Drosophila suzukii

Drosophila suzukii is the scientific name for the Asian fruit fly. The Drosophila suzukii causes enormous damage in the European and American vineyards because the female lays eggs in healthy ripening grapes. In contrast to their native variants (the most common is the Drosophila melanogaster), they have a much longer ovipositor and can therefore puncture the (thin) intact skin of healthy grapes. The native fruit fly cannot do this and therefore only lays eggs in already broken and / or rotting grapes. The larvae hatching from the eggs feed on the grapes and affect the harvest.
