line-trapping experiment histogram

When comparing catch numbers from a single pheromone trap for codling moth (Cydia pomonella) versus the mean catch of a line of five traps in a single location, researchers at Michigan State University found the line-trapping method to be far less prone to variability than the single-trap method. The range of the average line-trap catch in 36 tests was 1- 12, while the range of single-trap catches in those tests was 0-32.
