Modeling the spatial distribution of male western corn rootworm (Diabrotica virgifera virgifera) in refuge and Bt corn

We sampled male and female western corn rootworm in refuge and adjacent Bt corn blocks in 2006 and 2010. Samples were taken along a transect across both blocks at multiple times during a 30 day period. We used a simple model of emergence, mortality and dispersal (exponential function) to mimic the changes in distributions of males over time.
