This is a point that has been mentioned in many of the articles on this subject lately, and one of the research programs I read about is measuring exactly this. They took a bunch of volunteers and counted the number of bugs on their windshields after driving a certain distance to estimate the flying insect population in that area. And yes, there is a huge reduction in population. The more concerning statistic is that insect populations are also plummeting in remote rain forests with no pesticide use.
