花粉是蜜蜂的主要蛋白质来源，其质量和消化率是蜜蜂健康的重要因素。我们比较了八种不同的混合花粉饮食对无蜂王成虫生存和生理的影响。这些混合物代表了自然环境中蜜蜂的花粉来源。它们由三到五种家族花粉类型组成，蛋白质百分比从 8.4% 到 18.1% 不等。主要含有菊科花粉的混合物消耗较少，蜜蜂死亡率增加，表明这种花粉类型为蜜蜂提供的营养质量和同化能力较差。所有花粉饮食都促进卵巢激活，但在花粉处理组中，卵巢激活的蜜蜂百分比与饮食中的蛋白质含量无关，这表明卵巢激活可能还取决于其他营养素。存活率也与血淋巴中的卵黄蛋白原水平呈正相关。我们的结果表明，蛋白质消耗量和花粉类型影响蜜蜂的存活和生理机能。
Pollen is the main protein source for honey bees, and its quality and digestibility are important factors for bee health. We compared the effects of eight different mixed-pollen diets on queenless adult survival and physiology. The mixtures represented the pollen source for bees in a natural environment. They consisted of three to five familial pollen types, and the protein percentage varied from 8.4 to 18.1 %. The mixtures that contained mainly Asteraceae pollen were less consumed and enhanced bee mortality, suggesting that this pollen type offers poor nutritional quality and assimilation for the bees. All pollen diets promoted ovarian activation, but among the pollen treated groups, the percentage of bees with activated ovaries was not related to the protein content of the diet, which suggests that ovarian activation may also depend on other nutrients. Survival was also positively correlated to the vitellogenin levels in the hemolymph. Our results showed that the amount of protein consumption and the pollen type influenced bee survival and physiology.
