Yes. There is a new fruit and berry pest in the United States called the Spotted wing drosophila (SWD). This is a small vinegar fly which is native to Asia and has become a worldwide pest in the last decade. The fly can lay its eggs in lots of different berries with thin skins and is a major fruit pest in cherries, blueberries and raspberries. The only effective control is frequent insecticide application to kill the fly before it lays its eggs. Here is a link to more information with some suggested controls. http://www.ipm.msu.edu/invasive_species/spotted_wing_drosophila.
