Stressful conditions during development can have sub-lethal consequences on organisms aside from mortality. Using previously reported in-hive residues from commercial colonies, we examined how multi-pesticide exposure can influence honey bee (Apis mellifera) queen health. We reared queens in beeswax cups with or without a pesticide treatment within colonies exposed to treated or untreated pollen supplement. Following rearing, queens were open-mated and then placed into standard hive equipment in an "artificial swarm" to measure subsequent colony growth. Our treated wax had a pesticide Hazard Quotient comparable to the average in beeswax from commercial colonies, and it had no measurable effects on queen phenotype. Conversely, colonies exposed to pesticide-treated pollen had a reduced capacity for viable queen production, and among surviving queens from these colonies we observed lower sperm viability. We found no difference in queen mating number across treatments. Moreover, we measured lower brood viability in colonies later established by queens reared in treated-pollen colonies. Interestingly, royal jelly from colonies exposed to treated pollen contained negligible pesticide residues, suggesting the indirect social consequences of colony-level pesticide exposure on queen quality. These findings highlight how conditions during developmental can impact queens long into adulthood, and that colony-level pesticide exposure may do so indirectly.

:发育过程中的紧张状况除了会导致死亡以外,还可能对生物造成亚致死性后果。使用先前报道的来自商业菌落的蜂巢中的残留物,我们研究了多种农药暴露如何影响蜜蜂(Apis mellifera)女王的健康。在暴露于经过处理或未经处理的花粉补充剂的菌落中,我们将蜂王杯饲养在蜂蜡杯中,不论是否经过农药处理。饲养后,将蚁后打开交配器,然后将其放置在“人工群”中的标准蜂巢设备中,以测量随后的菌落生长。我们处理过的蜡具有与商业菌落中蜂蜡平均水平相当的农药危害指数,并且对女王表型没有可测量的影响。相反,暴露于杀虫剂处理的花粉的菌落具有降低的存活皇后生产能力,在这些菌落中存活的皇后中,我们观察到精子存活力较低。我们发现不同治疗方法的女王交配数没有差异。此外,我们在后来由处理过的花粉菌落饲养的皇后区建立的菌落中,测得了较低的繁殖力。有趣的是,暴露于经过处理的花粉的菌落的蜂王浆中农药残留量微不足道,这表明菌落水平的农药暴露对女王质量的间接社会影响。这些发现突显了发育过程中的条件如何影响成年后的女王,而菌落水平的农药暴露可能会间接地影响女王。
