Bumblebees play a significant role as pollinators for many wild plants and cultivated crops, owing to their elongated proboscis, resilience to diverse weather conditions, robustly furred bodies, and their unique capacity for buzz-pollination. To better understand the effect of greenhouse microclimates on bumblebee foraging behavior and working modes, a long-term record of foraging activity for each Bombus terrestris L. (Hymenoptera: Apidae) forager was monitored by the Radio-frequency identification system. The pattern of task performance, including constant housing, foraging, and day-off rotation, was examined under the microclimate. In addition, the correlation between foraging activity of bumblebees and temperature, relative humidity, illumination in the greenhouse, and pollen viability of tomato plants was further analyzed. Our findings revealed that B. terrestris can respond to microclimatic factors and plant resources while also exhibiting a suitable working pattern within the colony. Day-off rotation was observed as a strategy employed by foragers to prolong their survival time. This division of labor and task rotation may serve as strategies for the survival and development of the colony. Our research may contribute to fully understanding how microclimate and plants influence pollinator behavior within greenhouses, thereby optimizing the pollination management of bumblebees on greenhouse crops.
由于拥有细长的喙、对多种天气条件的适应能力、毛茸茸的身体以及独特的振翅授粉能力，大黄蜂在许多野生植物和栽培作物的授粉过程中发挥着重要作用。为了更好地了解温室小气候对大黄蜂觅食行为和工作模式的影响，利用射频识别系统对每只意大利蜜蜂（膜翅目：蜜蜂科）觅食者的觅食活动进行了长期记录。在小气候条件下，研究了任务执行模式，包括固定驻留、觅食和休息日轮换。此外，还进一步分析了大黄蜂觅食活动与温度、相对湿度、温室内光照以及番茄植株花粉活力之间的相关性。我们的研究结果表明，意大利蜜蜂能够对小气候因素和植物资源做出反应，同时在蜂群中展现出合适的工作模式。观察到休息日轮换是觅食者延长生存时间所采用的一种策略。这种分工和任务轮换可能是蜂群生存和发展的策略。我们的研究可能有助于全面了解小气候和植物如何影响温室内传粉者的行为，从而优化温室作物上大黄蜂的授粉管理。
