“…Bees fed diets deficient in linolenic (⍵3) acid have smaller hypopharyngeal glands and decreased learning acquisition (Arien et al 2015). Further, consumption of high ω6:ω3 ratio diets causes increased mortality and decreased brood rearing ability (Arien et al 2020).…”

“…We hypothesized that bees sampled from high-EFA hives would have more EFAs in their tissues than those from low-EFA hives. Next, given previous research suggesting that colonies forage for diets that rescue previous fatty acid deficiencies (Zarchin et al 2017) and the benefits of a balanced diet to honey bee health (Arien et al 2018(Arien et al , 2020, we assessed the foraging behavior of hives fed low-or high-EFA supplements. Hives were presented with an array of choice flours with varying levels of both EFAs.…”

Honey bees obtain lipids from pollen or commercial supplements. These supplements do not fully support colony health. We tested the hypothesis that supplements are deficient because they lack essential fatty acids (EFAs). The five supplements we tested had low linolenic (⍵3) acid and were unbalanced (⍵6:⍵3 > 6) compared to natural pollen. We selected two of these supplements for further study because they had different levels of individual EFAs and different ⍵6:⍵3 ratios. Bees from hives fed these different supplements had equivalent tissue EFA levels. In choice assays, hives fed these different supplements were presented with flours with various absolute and relative levels of EFAs. We saw no difference in foraging preference. Rather, all hives preferred flours with small grain size and high protein to lipid ratios. We conclude that bees balance their internal EFAs and that differential colony nutrition does not affect foraging preference. The data also argue for more linolenic (⍵3) acid in commercial supplements.

“…Both linoleic acid and linolenic acid have been linked to learning behavior and brood development in honey bees [ 28 , 29 , 30 , 31 ]. They have also been demonstrated to have bactericidal and antifungal activities, which can protect bees against pathogens [ 26 ].…”

“…Bee pollen is an essential source of fatty acids for honey bees. It not only is used for energy and as a structural component of cell membranes, but also plays crucial roles in bee health and behavior [ 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. Generally, the fatty acid content of pollen is dominated by saturated fatty acids, such as myristic acid (C 14:0 ), palmitic acid (C 16:0 ), and stearic acid (C 18:0 ), as well as unsaturated fatty acids, such as oleic acid (C 18:1 ), linoleic acid (C 18:2 ), and alpha-linolenic acid (C 18:3 ) [ 26 ].…”

Bee pollen is a nutrient-rich food that meets the nutritional requirements of honey bees and supports human health. This study aimed to provide nutritive composition data for 11 popular bee pollen samples (Brassica napus (Bn), Bidens pilosa var. radiata (Bp), Camellia sinensis (Cs), Fraxinus griffithii (Fg), Prunus mume (Pm), Rhus chinensis var. roxburghii (Rc), Bombax ceiba (Bc), Hylocereus costaricensis (Hc), Liquidambar formosana (Lf), Nelumbo nucifera (Nn), and Zea mays (Zm)) in Taiwan for the global bee pollen database. Macronutrients, such as carbohydrates, proteins, and lipids, were analyzed, which revealed that Bp had the highest carbohydrate content of 78.8 g/ 100 g dry mass, Bc had the highest protein content of 32.2 g/ 100 g dry mass, and Hc had the highest lipid content of 8.8 g/ 100 g dry mass. Only the bee pollen Hc completely met the minimum requirements of essential amino acids for bees and humans, and the other bee pollen samples contained at least 1–3 different limiting essential amino acids, i.e., methionine, tryptophan, histidine, valine, and isoleucine. Regarding the fatty acid profile of bee pollen samples, palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), and linolenic acid (C18:3) were predominant fatty acids that accounted for 66.0–97.4 % of total fatty acids. These data serve as an indicator of the nutritional quality and value of the 11 bee pollen samples.

“…Low diet diversity can expose bees to nutritional stress. It has been proven that adequate access to lipids determines the development of brood and affects the longevity and body structure of insects [ 46 , 47 ]. The pollen diet also influences the lipid content of the hemolymph.…”

Diet is an important factor in the proper development of the individual and the entire colony. A pollen diet affects honey bees in a number of ways. It can stimulate the number and type of hemocytes, the total number of proteins, carbohydrates and lipids, affect the histology of the middle intestine, and ensure the correct ontogenesis of the larvae. Moreover, selected single-flower diets can stimulate the development of the pharyngeal glands that produce royal jelly, thus conditioning the development of secretory immunity. Selected single-species pollen may also increase the phenol oxidase concentration, which contributes to the humoral response. A honey bee diet based on multi-flower pollen is more desirable than a mono-flower diet, but must be properly balanced.
