Vibrating bees are the main pollinators of the tomato plant (Solanum lycopersicum L.). Knowledge of other alternative food resources for these bees is fundamental for pollinator management actions in agricultural areas. The objective of this study was to evaluate the plants used as food resources for the main pollinators Bombus morio (Swederus) and Exomalopsis analis Spinola in plantation areas. The study was conducted in 12 plantation areas in São José de Ubá, southeastern Brazil, during the flowering period of S. lycopersicum. The pollen material contained on the hind legs of 40 B. morio females and 72 E. analis females was analyzed and compared with the reference slides made from 155 flowering plant species (35 botanical families) sampled close to the plantations. The pollen material was submitted to acetolysis and mounted in glycerin gelatin and analyzed under optical microscope. From B.morio corbiculae were identified 188 pollen types (52 identified from reference slides) and 189 types from E. analis scopae (54 in reference slides). Besides tomato pollen, other most abundant types belong to Fabaceae (8%) in B. morio samples, and Hyptis and Solanum sp in E. analis samples. The trophic niche overlap was close to zero when the tomato pollen was disregarded, indicating that both pollinators use distinct sources. The results confirm the generalist character of tomato pollinators; in addition, the use of floral resources from several other plants, even at tomato flowering peak, emphasizes the importance of maintaining flowering plant composition around agricultural areas.

番茄授粉的花粉负荷谱。

振动的蜜蜂是番茄植株（Solanum lycopersicum L.）的主要授粉媒介。了解这些蜜蜂的其他替代食品资源是农业地区授粉媒介管理行动的基础。这项研究的目的是评估种植园中主要传粉媒介Bombus morio（Swederus）和Exomalopsis analis Spinola用作食物资源的植物。这项研究是在巴西东南部的番茄开花期，在巴西东南部的圣何塞德乌巴的12个种植区进行的。花粉材料包含在40 B. morio雌性和72 E. analis的后腿上对雌性进行了分析，并与在种植园附近采样的155种开花植物物种（35个植物科）制成的参考幻灯片进行了比较。将花粉材料进行乙酰分解并固定在甘油明胶中并在光学显微镜下进行分析。从B.morio corbiculae被确定188种花粉类型（从参考幻灯片标识52），并从189种类型E. analis scopae（54参考幻灯片）。除番茄花粉外，其他最丰富的类型在桑布鲁芽孢杆菌样品中还属于豆科（占8％），在大肠杆菌中属于hyptis和茄属sp 。样品。当忽略番茄花粉时，营养位的重叠接近于零，表明两个传粉者使用不同的来源。结果证实了番茄授粉媒介的多面性。此外，即使在番茄开花高峰期，也要利用其他几种植物的花卉资源，强调保持农业地区周围开花植物组成的重要性。
