Model-based estimates of contrasts and corresponding significance levels of the treatment effect (neonicotinoid <i>versus</i> control) and honeybee genetics (strain A <i>vs.</i> strain B).

Results are shown in the transformed scale for the three response variables adult bees, eggs and larvae and pupae assessed directly after the 1.5 months of treatment (Summer 2011), 3.5 months later (Autumn 2011) and 1 year later (Spring 2012). For adult bees and eggs and larvae (the models that included a significant threefold interaction between treatment, honeybee strain and assessment date) contrasts for treatment effects were also computed within individual honeybee strains at each assessment date. P values are adjusted for multiple testing. ***P<0.001; **P<0.01; *P<0.05; · 0.05<P<0.1.
