Little fly – big problem for wine (Wine Spectator)
What made 2014 such a banner year for the new pest was the weather. “Mild winters and summers as well as wet weather are conducive to rapid population increase,” said Vaughn Walton, an associate professor in entomology at Oregon State University. “Spotted wing drosophila population [growth] reaches a peak during wine harvest.” In 2014, temperatures never got low or high enough in Europe to stave the frequent reproduction cycle of the fly, and humid weather around harvest exacerbated the infestation.
