In lowbush blueberry fields, we conducted residue analysis comparing flowers, trapped pollen (honey bee and spp.), and collected bees (honey bee workers, bumble bee queens, and non- spp. wild native bees). The study was conducted from 2012 to 2014. The number of pesticide residues, total concentrations, and risk to honey bees (Risk Quotient) on flowers were not significantly different from those determined for trapped honey bee pollen (except in one study year when residues detected in flower samples were significantly lower than residue numbers detected in trapped pollen). The compositions of residues were similar on flowers and trapped pollen. The number of residues detected in honey bee pollen was significantly greater than the number detected in spp. pollen, while the total concentration of residue was not different between the two types of pollen. The risk to honey bees was higher in trapped honey bee pollen than in trapped spp. pollen. The analysis of honey bee workers, native bumble bee queens, and native solitary bees showed that although more pesticide residues were detected on honey bee workers, there were no differences among the bee taxa in total residue concentrations or risk (as estimated in terms of risk to honey bees).
在矮丛蓝莓田中，我们进行了残留分析，比较了花朵、捕获的花粉（蜜蜂和其他物种）以及采集到的蜜蜂（工蜂、熊蜂蜂后和其他非特定物种的野生本地蜜蜂）。该研究于2012年至2014年进行。花朵上的农药残留数量、总浓度以及对蜜蜂的风险（风险商数）与捕获的蜜蜂花粉所测定的结果没有显著差异（除了在一个研究年份，花朵样本中检测到的残留量显著低于捕获花粉中检测到的残留量）。花朵和捕获花粉上的残留成分相似。蜜蜂花粉中检测到的残留数量显著多于其他物种花粉中检测到的数量，而两种花粉的残留总浓度没有差异。捕获的蜜蜂花粉对蜜蜂的风险高于捕获的其他物种花粉。对工蜂、本地熊蜂蜂后和本地独居蜜蜂的分析表明，尽管在工蜂上检测到更多的农药残留，但在总残留浓度或风险方面（以对蜜蜂的风险估计），蜜蜂类群之间没有差异。
