蜜蜂为许多粮食作物提供重要的授粉服务，对支持野生植物多样性至关重要。然而，由于农业集约化和栖息地丧失，群居蜜蜂和独居蜜蜂的花粉食物来源的饮食景观已经发生了变化。因此，了解蜜蜂的基本营养代谢并满足其营养需求正成为农业和保护的迫切要求。我们知道花粉是传粉者食用脂肪和固醇的主要来源，但对必需营养素是什么以及需要多少的精确理解尚不清楚。甾醇是产生控制发育的激素的关键，可能存在于细胞膜中，其中含脂肪酸的物质是重要的结构和信号分子（磷脂）或供应，储存和分配能量（甘油酯）。在这篇重要的综述中，我们从各种文献来源研究了目前对社会和孤独蜜蜂的固醇和脂质代谢的一般认识，并讨论了对蜜蜂健康的影响。我们发现，虽然真社会性蜜蜂对固醇供应的某些饮食变化有弹性，但这种范围是有限的。从头脂肪生成和饮食需要特定的脂肪酸（FA）的证据表明，在昆虫中的FA代谢类似于哺乳动物，但具有独特的功能。蜜蜂依赖于它们的饮食摄入的必需固醇和脂质的方式是依赖于花粉的可用性。
Bees provide essential pollination services for many food crops and are critical in supporting wild plant diversity. However, the dietary landscape of pollen food sources for social and solitary bees has changed because of agricultural intensification and habitat loss. For this reason, understanding the basic nutrient metabolism and meeting the nutritional needs of bees is becoming an urgent requirement for agriculture and conservation. We know that pollen is the principal source of dietary fat and sterols for pollinators, but a precise understanding of what the essential nutrients are and how much is needed is not yet clear. Sterols are key for producing the hormones that control development and may be present in cell membranes, where fatty-acid-containing species are important structural and signalling molecules (phospholipids) or to supply, store and distribute energy (glycerides). In this critical review, we examine the current general understanding of sterol and lipid metabolism of social and solitary bees from a variety of literature sources and discuss implications for bee health. We found that while eusocial bees are resilient to some dietary variation in sterol supply the scope for this is limited. The evidence of both de novo lipogenesis and a dietary need for particular fatty acids (FAs) shows that FA metabolism in insects is analogous to mammals but with distinct features. Bees rely on their dietary intake for essential sterols and lipids in a way that is dependent upon pollen availability.
