Probability distributions calculated from total yearly densities of Halyomorpha halys captured from black light traps placed on farms from 2004 to 2011 using Bayesian linear regression and the reversible jump MCMC algorithm.

For relationships between H. halys and landscape/land use data to be considered informative, the posterior distribution of that relationship must be 0.05 or greater [(i.e. α-level = 0.05), indicating a statistically significant relationship].
