Researchers are tackling what they call “cultural tactics” to determine nonchemical farming practices — such as pruning and thinning techniques or netting — that can be brought into play to thwart spotted wing drosophila in organic orchards, vineyards and fields. In one project of blueberries and raspberries, researchers plan to adjust the temperature and humidity inside the canopy, where the insects mate and reproduce. “How can we use pruning to open the canopy to more light? Can we create a less favorable habitat?” said Dr. Mary Rogers, University of Minnesota entomologist and organic project co-director. They plan to evaluate the […]
