Abstract

Background: Pesticides in aquatic environments are frequently studied, yet those in terrestrial environments remain relatively unexplored. This study monitored bee bread collected from two apiaries located in a typical agricultural environment in Switzerland from March to August 2022 as a proxy for terrestrial pesticide inputs. The temporal appearance of the selected pesticides was compared to their profiles in the water of a small catchment within this area.

Results: Overall, 62% (31 of 50) of the targeted pesticides were detected in bee bread, with occurrences in both apiaries largely overlapping (23 pesticides), demonstrating a similar agricultural landscape across the region. Furthermore, nine pesticides were detected in bee bread and water, two pesticides were detected only in bee bread, and two additional pesticides were detected only in water. Comparative temporal analysis revealed that pesticides with moderate-to-high movement potential [Groundwater ubiquity score (GUS) ≥ 2.19] appeared simultaneously in bee bread and water (azoxystrobin, boscalid, flufenacet and terbuthylazine). However, pesticides with low movement potential (GUS ≤ 1.86) showed different profiles in both matrices (cyprodinil, prosulfocarb, tebuconazole and thiacloprid), indicating the difficulty of predicting their fate, given that they adhere to soil particles and cannot be covered by current water monitoring programmes.

Conclusion: Our findings present bee bread as a viable biomarker for monitoring pesticides by complementing the conventional water monitoring, and permitting a more comprehensive assessment of the exposure of terrestrial organisms to pesticides. Bee bread allows immediate recording of the applied pesticides and promptly reflects the seasonal variation in pesticide use. © 2024 The Author(s).

蜜蜂（Apis mellifera）收集的蜜蜂面包作为陆地农药生物标志物，补充了水研究。

背景：人们经常对水生环境中的农药进行研究，但对陆地环境中的农药研究相对较少。这项研究对 2022 年 3 月至 8 月期间从瑞士典型农业环境中的两个养蜂场采集的蜜蜂面包进行了监测，以此作为陆地农药输入的替代物。研究人员将所选农药在时间上的表现与该地区一个小型集水区水中的农药含量进行了比较：结果：总体而言，62%的目标农药（50 种中的 31 种）在蜜蜂面包中被检测到，在两个养蜂场中的出现率基本重叠（23 种农药），这表明整个地区的农业景观相似。此外，在蜜蜂面包和水中检测到 9 种农药，仅在蜜蜂面包中检测到 2 种农药，另有 2 种农药仅在水中检测到。时间比较分析表明，具有中高移动潜力[地下水泛在性得分（GUS）≥ 2.19]的农药（唑螨酯、啶虫脒、氟虫酰胺和特丁津）同时出现在蜜蜂面包和水中。然而，移动潜力低（GUS ≤ 1.86）的农药（腈菌唑、丙硫克百威、戊唑醇和噻虫啉）在两种基质中显示出不同的特征，这表明很难预测它们的归宿，因为它们附着在土壤颗粒上，无法被目前的水监测计划覆盖：我们的研究结果表明，蜜蜂面包是监测杀虫剂的一种可行的生物标志物，它是对传统水监测的补充，可以更全面地评估陆地生物接触杀虫剂的情况。蜜蜂面包可以立即记录施用的农药，并及时反映农药使用的季节性变化。© 2024 作者简介害虫管理科学》由约翰-威利-森斯有限公司代表化学工业协会出版。
