Air pollutants and agricultural pesticides can be environmental stressors to pollinators. In this study, to investigate the expression of detoxification-related genes and heavy metal concentrations in honey bees and honey possibly exposed to environmental stresses, we collected samples from apiaries located in mountainous, agricultural, and urban areas. Compared with the mountainous and agricultural areas, the mercury and lead concentrations were highest in honey and bees collected from urban areas. In addition, the expression levels of CYP9Q1 , CYP9Q2 , CYP9Q3 , and genes encoding catalase and superoxide dismutase were markedly higher in urban bees than those from agricultural and mountainous areas, discreetly indicating that the notable induction of the detoxification metabolism in urban bees might be because of heavy metal pollutant exposure. Our study suggests that honey bees actively respond to environmental stressors, such as heavy metals derived from urban areas.

环境重金属对蜜蜂Apis mellifera解毒相关基因表达的影响

空气污染物和农用杀虫剂可能是传粉媒介的环境压力源。在这项研究中，为了调查可能暴露于环境压力的蜜蜂和蜂蜜中解毒相关基因的表达和重金属浓度，我们从位于山区、农业和城市地区的养蜂场收集了样本。与山区和农业地区相比，从城市地区采集的蜂蜜和蜜蜂中汞和铅的浓度最高。此外，城市蜜蜂的CYP9Q1、CYP9Q2、CYP9Q3以及编码过氧化氢酶和超氧化物歧化酶的基因的表达水平明显高于农业和山区的蜜蜂，谨慎地表明城市蜜蜂对解毒代谢的显着诱导可能是因为重金属污染物暴露。
