Summary of main results of impacts of three different doses of thiamethoxam (treatment) on life-history traits of four species of bumblebee queen. As infected and escapee queens were excluded from analyses, the total number of uninfected queens represents the individuals used for analyses. The average daily syrup consumption was calculated for uninfected queens only. The average terminal oocyte length was calculated for uninfected queens that survived the full four-week experiment. Averages presented are means ± s.e.
