The study concerns a 220-acre area. To extrapolate from that to the world is a mistake. From what I believe is the original paper (copy at http://www.bouldercountybeekeepers.org/wp-content/uploads/2016/02/Orbrioch-Nature-reserve.pdf http://www.bouldercountybeekeepers.org/wp-content/uploads/20... ): "The results show that, in the same two areas, sampled in the years 1989 and 2013, there was a dramatic fall in the number of flying insects. Using the same traps, in the same areas, significant reductions of insect populations, of more than 75%, were found. Our data confirms, that in the areas studied, less than 25% of the original number of flying insects collected in 1989, were still present in 2013. Orboicher Bruch Area The Orboicher Bruch, to the Northwest of Krefeld, is a designated Nature Reserve of around 100 hectares (220 acres). Due to the reserve’s relatively remote location and its rugged landscape, intensive farming came to the area only recently."
