传粉媒介在全球范围内正在减少，农业杀虫剂是一个潜在的驱动因素。最近的研究表明，杀虫剂可能会显着影响大黄蜂的殖民地，一个重要的和下降的授粉群体。在这里，我们表明，殖民地成立皇后，一个关键的，但脆弱的阶段，大黄蜂的生命周期，是不太可能启动一个殖民地后，暴露于噻虫嗪，一种烟碱类杀虫剂。熊蜂terrestris皇后暴露于现场相关水平的噻虫嗪，和两个自然的压力源，寄生虫Crithidia bombi，和不同的冬眠持续时间。暴露于噻虫嗪产生的比例减少了26%的皇后产卵，并提前殖民地启动的时间，虽然我们没有检测到任何实验治疗的影响，皇后产生成年后代的能力，在14周的实验期间。正如先前的研究所预期的那样，冬眠时间也对产卵有影响，但与杀虫剂处理没有显著的相互作用。对殖民地减少26%对种群动态的影响进行建模，大大增加了种群灭绝的可能性。这表明，类尼古丁可以影响大黄蜂生命周期的这一关键阶段，并可能对种群动态产生重大影响。
Pollinators are in global decline, and agricultural pesticides are a potential driver of this. Recent studies have suggested that pesticides may significantly impact bumblebee colonies, an important and declining group of pollinators. Here we show that colony founding queens, a critical yet vulnerable stage of the bumblebee lifecycle, are less likely to initiate a colony after exposure to thiamethoxam, a neonicotinoid insecticide. Bombus terrestris queens were exposed to field-relevant levels of thiamethoxam, and two natural stressors, the parasite Crithidia bombi, and varying hibernation durations. Exposure to thiamethoxam produced a 26% reduction in the proportion of queens that laid eggs, and advanced the timing of colony initiation, although we did not detect impacts of any experimental treatment on the ability of queens to produce adult offspring during the 14-week experimental period. As expected from previous studies, hibernation duration also had an impact on egg laying, but there was no significant interaction with insecticide treatment. Modelling the impacts of a 26% reduction in colony founding on population dynamics dramatically increased the likelihood of population extinction. This shows that neonicotinoids can affect this critical stage in the bumblebee lifecycle, and may have significant impacts on population dynamics.
