Abstract A number of experiments were conducted targeting the effect feeding with pollen substitutes or supplements, sugar solutions, artificial flavors, and delivery methods on various activities honey bees. The results showed that regular yeast was most fastest consumed, a significant difference from other types dough. placing dough inside hives increasing foraging After one day setting dough, recorded lowest remaining weight, which 22.67 It consumed compared to rest dough‥ Before bees ranged 19.33 22.50 bee/minute 19.83 50.83 bee/minute, respectively after has also been observed food flavors before increases flavor strawberry flavor, volume 300 ml first two hours presenting solution containing flavor. highest rate as result treatments 70.83, 22.66 for second days, rates applying 46.33 18.66 respectively. increased duration bees’ temporal memory days experiment progressed, period began increase flavor-containing solution, 30 minutes reached 4 last experiment. study possibility using in nutrition consumption stimulate accept alternatives.

A guide to sunflowers: floral resource nutrition for bee health and key pollination syndromes

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: May 1, 2025

Sunflower, Helianthus annuus L., is a prominent global oilseed crop with rising cultivation and appeal as bee-friendly plant by providing abundant floral resources for pollinators. Mass-flowering crops can increase the availability of resources, sunflower good opportunity to relieve pollen scarcity during late summer in agricultural landscapes. Yet this should be taken caution they also provide homogeneous source nutrition. This study aimed review summarize nutritional profile pollen, nectar, bee bread, honey, while assessing their effects on survival, development, health. Furthermore, we present here general state knowledge additional pollinator syndromes that extend beyond including those influencing visual olfactory attraction. We found pollen’s quality questioned due lower protein amino acid deficiencies, its nutrient content, like nectar sugars, had large variability. Sunflower consumption showed mixed Apis mellifera Bombus species, sometimes negatively impacting development survival. However, studies have conveyed positive impact health consistently reduced infection intensity gut parasite, Crithidia bombi , species. probes question defining emphasizing need when categorizing low resource. outlines importance characteristics (sugar content volume) morphology (flower pigmentation corolla length) foraging preferences. A gap persists regarding chemistry sunflowers’ extensive volatile better understand pollination drive interactions.

The Effects of Artificial Diets Containing Free Amino Acids Versus Intact Proteins on Biomarkers of Nutrition and Deformed Wing Virus Levels in the Honey Bee

Insects, Journal Year: 2025, Volume and Issue: 16(4), P. 375 - 375

Published: April 2, 2025

Pollen is bees’ primary source of proteins. Using pollen substitutes could reduce colony losses in areas with limited floral resources. In this study, we compared the effects made from intact proteins versus free amino acids on bee survival, as well levels vitellogenin (vg), major royal jelly protein 1 (mrjp1), and deformed wing virus (DWV). Our study revealed no significant differences vg mRNA between bees fed acid diets. However, mrjp1 were higher diets, suggesting that availability affects expression nutritionally regulated gene differently. Thus, combined be used to assess nutritional value different substitutes. results also indicate diets rich exhibited high DWV increased mortality during first week, even though they showed a genes related good nutrition. contrast, an diet lowest two weeks, although viral infection afterward. These suggest ingested are quickly absorbed intestine, transported hemolymph, taken up by cells, where can facilitate replication. On other hand, may undergo slower digestion gradual release which not trigger overt infection. Possible interactions among Varroa mites, infection, nutrition discussed.

Effects of a supplemented diet containing 7 probiotic strains (Honeybeeotic) on honeybee physiology and immune response: analysis of hemolymph cytology, phenoloxidase activity, and gut microbiome

Biological Research, Journal Year: 2024, Volume and Issue: 57(1)

Published: Aug. 7, 2024

Abstract Background In this study, a probiotic mixture (Honeybeeotic) consisting of seven bacterial strains isolated from unique population honeybees ( Apis mellifera ligustica ) was used. That honeybee located in the Roti Abbey locality Marche Region Italy, an area human activities, and genetic contamination other populations. The aim to investigate effects on innate immunity intestinal microbiome healthy common two hives same apiary. Hive A received diet 50% glucose syrup, while hive B syrup supplemented with probiotics, both administered daily for 1 month. To determine whether altered immune response, phenoloxidase activity hemolymph cellular subtype count were investigated. Additionally, metagenomic approaches used analyze gut microbiota composition function, considering critical role plays modulating host physiology. Results results revealed differences hemocyte populations between hives, as exhibited higher counts oenocytoids granulocytes. These findings indicated that dietary supplementation safe well-tolerated. Furthermore, significantly decreased (1.75 ± 0.19 U/mg) compared (3.62 0.44 U/mg, p < 0.005), suggesting improved state well-being honeybees, they did not require activation defense mechanisms. Regarding composition, modulated control, retaining core components causing positive negative variations. Notably, several genes, particularly KEGG genes involved amino acid metabolism, carbohydrate branched-chain (BCAA) transport, more abundant probiotic-fed group, effective nutritional supplement host. Conclusions This study advocated feeding induces beneficial immunological promoted balanced enhanced metabolic activities related digestion. use highly selected probiotics shown contribute overall improving their response health.

Optimal competitors: the balance of attraction and choices of mutualists, like pollinators, drives facilitation and may promote crop pollination

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 1, 2024

Abstract When two species use the same resource, this typically leads to competition, such as when different plants aim attract mutualist pollinators. However, more flowers may also pollinators area. Depending on which process dominates, one or both ‘competitors’ actually benefit from other’s presence: a phenomenon called ‘pollination facilitation’ in plant ecology. For example, it has been argued that strips of wildflowers planted next crops who ‘spill over’ into crop. Here we mathematically examine tradeoff between facilitation and competition consumer attraction. We show contrary previous claims, no accelerating benefits density per se are necessary for facilitation. Instead, under very general assumptions, an imbalance local joint attraction consumers can generate at least ‘competitor’. This maximal crop low presence highly attractive ‘wildflowers’ (i.e. share with crop). Our results generalize many contexts where trade off consumers. In situations, exact effect competitor qualitatively shape outcomes, including competition.
