Ein Winzling lehrt das Fürchten: Die invasive Kirschessigfliege – ein bedeutender Schädling

Abstract

The invasive Spotted Wing Drosophila – a significant pest. The Spotted Wing Drosophila (Drosophila suzukii), native in South-East Asia, is an invasive pest belonging to the small fruit fly family of Drosophilidae, also named vinegar flies. Apparently displaced by global trade to the USA and Europe, this pest was able to disperse enormously over the continents since 2008. Ideal preconditions for this spread were suitable climatic conditions, the availability of a wide variety of host plants and the use of an ecological niche, namely healthy ripening and ripe fruits. In addition, D. suzukii is highly reproductive and owns excellent overwintering strategies. The Spotted Wing Drosophila is difficult to control and causes enormous damage.
