Water is an important resource for stingless bees, serving for both honey dilution and the composition of larval food inside nests, yet can be an important route of exposure to pesticides. Assuming bees can forage naturally on pesticide-contaminated or noncontaminated areas, we investigated whether water supply influences the choice between neonicotinoid-dosed or nondosed feeders and on mortality of the stingless bee, Melipona scutellaris (Latreille, Hymenoptera, Apidae). At the field concentration, there was no significant mortality; however, the bees were not able to distinguish the feeders. In the cages containing high-concentration feeders, with water supply, the bees preferred nondosed food, and with no water, the mortality increased. Considering that in the field it is common to find extrapolated concentrations, our work suggested that water may allow avoidance of high dosed food and minimize mortality.

供水是否是无St蜜蜂中毒的关键因素？

水是无刺蜜蜂的重要资源，既可以稀释蜂蜜，又可以筑巢内幼虫食物的组成，但也可以是接触农药的重要途径。假设蜜蜂可以在受到农药污染或未污染的地区自然觅食，我们调查了供水是否会影响新烟碱剂量或非剂量喂食器之间的选择，以及无刺蜜蜂黄lip（Melipona scutellaris）的死亡率（Latreille，Hymenoptera，Apidae）。在野外集中时，没有明显的死亡率。但是，蜜蜂无法区分饲养者。在装有高浓度喂食器的笼子中，有水供应，蜜蜂更喜欢无剂量食物，没有水，死亡率增加。考虑到在外地发现外推浓度很普遍，我们的工作表明水可以避免高剂量食物的使用并使死亡率最小化。
