The vinegar fly (Drosophila melanogaster) is the most common species of the insect family (also fruit flies). These are the most important and most commonly used experimental animal in heredity research. In agriculture, the insect appears as a large pest. It mainly affects in fermentation passed fruits and fruits of all kinds and lays its eggs there. Rapid propagation can cause great damage. A female lays 15 to 25 eggs a day and 500 to almost 1,000 eggs during its lifetime, which develop into larvae within 24 hours. These live from yeasts and bacteria, Within two weeks (in a warm climate in just eight days) a generation (from egg to egg) with three larval stages is run through. The hibernation takes place as a doll. On the vine, the flies can eat damaged berries microorganisms how Acetobacter (Acetic acid bacteria) and thereby the acid rot cause. The insect can also be in the basement during fermentation vinegar sting cause.
A second, very closely related species is that of Japan native cherry vinegar fly (Drosophila suzukii). It was first launched in 2008 California discovered and spread from there to many neighboring US states. In 2009 the insect was observed in some European countries such as Spain, France, Italy and Slovenia, and from 2011 also in Switzerland, Austria and Germany. This can affect many host plants, with red fruits such as cherries, strawberries, raspberries or red wine grapes being preferred. In the meantime, this new pest has become a real threat to fruit and viticulture. Due to the short generation cycle, the vinegar flies are difficult to take insecticides combatted. After an infestation, the breeding sites must be destroyed or further spread through disrupter (Pheromone traps) can be prevented. See a list of all pests and diseases below Vine enemies,
