Nosema ceranae and pesticide exposure can contribute to honey bee health decline. Bees reared from brood comb containing high or low levels of pesticide residues were placed in two common colony environments. One colony was inoculated weekly with N. ceranae spores in sugar syrup and the other colony received sugar syrup only. Worker honey bees were sampled weekly from the treatment and control colonies and analyzed for Nosema spore levels. Regardless of the colony environment (spores+syrup added or syrup only added), a higher proportion of bees reared from the high pesticide residue brood comb became infected with N. ceranae, and at a younger age, compared to those reared in low residue brood combs. These data suggest that developmental exposure to pesticides in brood comb increases the susceptibility of bees to N. ceranae infection.
微孢子虫和农药暴露会导致蜜蜂健康状况下降。将从含有高或低农药残留的巢脾中培育的蜜蜂放置在两种常见的蜂群环境中。一个蜂群每周用微孢子虫孢子糖水接种，另一个蜂群只接受糖水。每周从处理和对照蜂群中抽取工蜂蜜蜂样本并分析 Nosema 孢子水平。无论蜂群环境（添加孢子+糖水或仅添加糖水）如何，与从低残留巢脾中培育的蜜蜂相比，从高残留巢脾中培育的蜜蜂有更高的比例感染了微孢子虫，而且感染的年龄更小。这些数据表明，在巢脾中发育时接触农药会增加蜜蜂对微孢子虫感染的易感性。
