蜜蜂使用的花源可以通过分析从它们的身体、粪便、育雏室或巢中的储存罐中获得的花粉粒来识别。除了关于资源可用性的数据外，这些信息还有助于调查蜜蜂对食物资源的选择。我们评估了Scaptotrigona aff的觅食模式。depilis在城市化地区的季节性可用的食物资源。该蜂的种类占可利用植物群的36.60%，表明该蜂在时空尺度上具有选择性。当有许多类型的资源可用时，工人们将他们的收集活动集中在有限的一组资源上。与此相反，更多的植物物种被利用期间开花植物的数量较少。对所研究群体的每月觅食模式的分析表明，蒲桃（Syzygium cumini）（88.86%），含羞草（Mimosa sp.1）（80.23%），黑木（Schinus terebinthifolius）（63.36%）和桉树（Eucalyptus citriodora）（61.75%）是最常用的物种，因此对维持S. aff.在研究区域的脱毛。这些植物靠近殖民地，并表现出大量开花。这项研究是为数不多的工程，以量化自然资源的可用性，并分析开花季节性对蜜蜂的食物来源的选择的影响。
The floral sources used by bees can be identified by analyzing pollen grains obtained from their bodies, feces, brood cells, or storage pots in the nests. In addition to data on resource availability, this information enables the investigation on the selection of food resource by bees. We assessed the foraging patterns of Scaptotrigona aff. depilis in an urbanized area with seasonal availability of food resources. The species visited a percentage of 36.60% of the available flora, suggesting that these bees are selective at spatiotemporal scale. When many types of resources were available, the workers concentrated their collection activities on a limited group of sources. In contrast, more plant species were exploited during periods of lower number of flowering plants. A monthly analysis of the foraging patterns of the studied colonies revealed that Syzygium cumini (88.86%), Mimosa sp.1 (80.23%), Schinus terebinthifolius (63.36%), and Eucalyptus citriodora (61.75%) were the most frequently used species and are therefore important for maintaining S. aff. depilis at the study area. These plants are close to the colonies and exhibit mass flowering. This study is one of few works to quantify natural resource availability and to analyze the effects of flowering seasonality on the selection of food sources by bees.
