缓解欧洲蜂箱的营养压力有助于增强对寄生虫感染的抵御能力，并减少农药的相互作用。在此，我们通过田间试验来评估花增强对减少蜜蜂暴露于杀虫剂的有效性。一种大规模开花的作物，白芥菜，在一个由10个蜂箱组成的试验性养蜂场附近的一小块土地上种植。为了评估每个蜂箱中蜜蜂使用花块的频率，我们在白芥菜花上觅食的蜜蜂身上贴上电子标签，并在相邻稻田喷洒杀虫剂前一天记录每个蜂箱中有标签的蜜蜂的数量。蜂箱入口附近的尸体数量在喷洒后的一天内增加，但在蜂箱之间有所不同。被标记的蜜蜂数量与每个蜂巢的累积尸体数量呈显著负相关。我们建议将觅食蜜蜂吸引到蜂房附近的大量开花资源有助于降低杀虫剂暴露风险。
Alleviating nutritional stress in European honeybee hives helps to increase resilience to parasite infections and reduces the interactive effects of pesticides. Here, we used a field experiment to evaluate the effectiveness of floral enhancement in reducing bee exposure to insecticides. A mass-flowering crop, white mustard, was cultivated in a small patch near an experimental apiary comprising 10 hives. To assess the frequency of floral patch use by bees in each hive, we attached electronic tags to bees foraging on white mustard flowers and then recorded the number of tagged bees in each hive a day before insecticide spraying in the adjacent paddy fields. The number of corpses around hive entrances increased within a day after the spraying but varied among hives. There was a significant negative correlation between the number of tagged bees and the cumulative number of corpses at each hive. We suggest that attracting foraging bees to mass-flowering resources near an apiary helps to reduce insecticide exposure risk.
