“…There are at least 25 sterols recorded from plant pollen (Zu et al, 2021 ), with as many as twelve sterols detected in pollen of any individual species (Rasmont et al, 2005 ; Svoboda et al, 1983b ; Vanderplanck et al, 2020 ; Zu et al, 2021 ). The pollen sterolome of Populus fremontii and Hypochoeris radicata is dominated by cholesterol (C 27 , δ5; Standifer et al, 1968 ; Vanderplanck et al, 2020 ), whereas the sterolome of Zea mays, Prunus avium and P. spinosa is dominated by 24-methylenecholesterol (C 28 , δ5; Guo et al, 1995 ; Standifer et al, 1968 ; Villette et al, 2015 ; Zu et al, 2021 ). The pollen of Alnus glutinosa and Calluna vulgaris is mainly ß-sitosterol (C 29 , δ5; Standifer et al, 1968 ; Vanderplanck et al, 2020 ), whereas that of Helianthus spp.…”

Background 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). Aim of the review 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. Key scientific concepts of review 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.
