Figure 1.
The proportion of B. terrestris queens that had undergone a short (6 week) or long (12 week) hibernation, and had either been exposed to the pesticide thiamethoxam or a control, which initiated a colony (by laying eggs) within ten weeks of emergence from hibernation. Total sample size for each treatment group: short hibernation, control group = 50; short hibernation, pesticide group = 49; long hibernation, control group = 48; long hibernation, pesticide group = 50 queens (includes queens which survived the whole experiment only).
