Nesting blocks from which cocoons were harvested were either situated in a landscape with OSR fields treated with clothianidin seed dressing (test site) or untreated fields (reference site) and placed at the edge of the fields (edge) or ca. 100 m distant from the fields (distant). Summary of Poisson GLMM Results. Study location ORC (reference site) was excluded from the evaluation as an outlier. The intercept is the estimated mean value of the dependent variable, when all continuous variables are held at 0 and all categorical variables are held at their baseline levels. Positive values indicate positive interaction, negative values indicate negative interaction. Given are parameter estimates ± standard deviation
