ABSTRACT: German winemakers have recently paid attention to a species of Asian fruit fly that has attacked European vineyards and caused fruit rot. ABSTRACT: German winemakers have become the latest in Europe to raise concerns over an Asian fruit fly that causes grapes to rot in the vineyards. . Mo-Rhe-Na, the German wine export organization, said the pests had a serious impact on Dornfelder and Regent grapes. The name of the group is taken from the abbreviations of Mosel, Rheingau and Nahe. According to the winemakers in these areas, the infected grapes are no longer available for wine, and an estimated one-third of the Danfield grapes have been destroyed, and there is nothing people can do about it. In fact, not only in Germany, but also in other European regions such as Bordeaux, Burgundy and Veneto, the harm of cherry flies has been reported. The fruit fly was found in Baden in 2011 at the Wine Institute, but it was not serious. Probably last year's warm winter angels, these Drosophila flies overwintered and multiply. Therefore, measures must be taken to combat the harm of Drosophila. Some winemakers have to harvest red grapes ahead of time to reduce losses. Unlike other fruit flies that eat ripe grapes, cherry fruit flies attack immature grapes, lay eggs on them, and hatch larvae feed on grapes. Nevertheless, German grape production in 2014 was 25% higher than in 2013, and 1.8 million bottles of wine are expected to be produced.
