- As native bee populations decrease, there is a need to better understand their nutritional requirements to sustain healthy pollinator populations. A common native bee to eastern North America is the small carpenter bee, Ceratina calcarata. Previous studies have shown that the primary pollen sources for C. calcarata consist of clover and rose.
- The aim of this study is to compare the effects of diet composition on body size, development and survival. Artificial pollen diets were created using five different ratios of commercially available clover and rose pollen.
- Diets containing higher ratios of clover pollen produced larger individuals with increased survival rates and faster development times. To examine this further, the macronutrient profiles of clover and rose pollen were characterised comparing: protein, sugar, fatty acid, and amino acid content. Results indicated that rose pollen contained significantly higher protein and sugar content, while clover pollen had higher concentrations of essential amino acids. These are crucial to bee health and development, which helps to explain the increased survivorship observed on high clover diet treatments.
- Taken together, these results show that clover pollen provides a higher quality diet for larval development and survival of the native small carpenter bee. This research indicates that diet has a significant effect on the health of the native pollinator community and more research is needed to further explore the balance between pollen quality and availability, including essential macronutrients and the availability of these floral sources for wild bees.

花粉成分显着影响本地小型木匠蜜蜂Ceratina calcarata的发育和生存
- 随着本地蜂种群的减少，有必要更好地了解其营养要求，以维持健康的传粉媒介种群。北美东部常见的本地蜜蜂是小木匠蜜蜂Ceratina calcarata。先前的研究表明，C。calcarata的主要花粉来源包括三叶草和玫瑰。
- 这项研究的目的是比较饮食组成对体重，发育和生存的影响。人造花粉饮食是使用五种不同比例的市售三叶草和玫瑰花粉制成的。
- 含有较高三叶草花粉比例的饮食可以使较大的个体具有更高的存活率和更快的发育时间。为了进一步检查这一点，对三叶草和玫瑰花粉的常量营养素特征进行了比较：蛋白质，糖，脂肪酸和氨基酸含量。结果表明玫瑰花粉中蛋白质和糖的含量明显较高，而三叶草花粉中的必需氨基酸浓度较高。这些对蜜蜂的健康和发育至关重要，这有助于解释在高三叶草饮食疗法中观察到的存活率增加。
- 综上所述，这些结果表明三叶草花粉为本地幼小木匠蜜蜂的幼虫发育和生存提供了更高质量的饮食。这项研究表明，饮食对本地授粉媒介社区的健康具有重大影响，需要开展更多研究以进一步探索花粉质量与可利用性之间的平衡，包括必需的大量营养素和野生蜂这些花源的可利用性。
