Figure 1. Mean abundances (number per 1 min. survey) of egg masses, nymphs, and adults of Halyomorpha halys for plants of non-Asian (blue) and Asian (orange) origins.

The mean estimates were derived from Poisson-lognormal GLMM (egg masses) and LMEs (nymphs and adults). Plotted are back transformed model estimated means (thickened horizontal line) and SE (log link function for egg mass, and cube root transformation for nymphs and adults). Tukey’s post hoc comparisons are all significant at α = 0.05.
