Abstract Honey bees play a crucial role in agricultural production. Farmers rely on commercial bee pollination to obtain optimal yields, and beekeepers the income from fees. However, confronts honey with pests pathogens, pesticides, low-quality food, which many cases do not fulfill minimal nutritional requirements of bees.

Abstract Floral traits describe organs or structures directly related to plant reproduction, and they are essential understanding plant–pollinator interactions, notably for conservation purposes. The growth of trait‐based approaches lies in the availability data shared by international research community on dedicated platforms, as well protocols compiled handbooks how measure these a standardized way. important pieces that missing from handbooks, likely due complexity flower morphology.

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.

Abstract Pollen and nectar are crucial resources for bees but vary greatly among plant species in their quantity, nutritional quality timing of availability. This makes it challenging to identify an appropriate range plants meet the needs throughout year, though this information is important design pollinator conservation schemes. Using DNA metabarcoding pollen loads, we record floral resource use UK farmland bumblebees at different stages colony lifecycle, compare with null models ‘expected’ based on landscape‐scale availability (pollen nectar), foraging priorities preferences. We approach ask three main questions: (i) what breadth individual bumblebees?; (ii) do utilise a greater or lesser diversity than expected if they foraged proportion availability?; (iii) which preferentially utilise? Individual from highly consistent number taxa (mean: 10 ± 0.37 SE per bee), regardless species, sampling site time year. high consistency breadth, despite large changes identity availability, implies strong behavioural tendency towards fixed resources. effect was most striking April when maintained very low landscape‐level diversity. Bumblebees used some significantly more predicted abundance, supply, implying certain desirable characteristics beyond mere quantity resource. These included Allium spp. Vicia April; Trifolium repens Lotus corniculatus July Cardueae (thistles) Taraxacum officinale September. Practical implication : Our results strongly indicate that not only factor driving bumblebee patterns also factors. Thus, addition providing quantities resources, recommend schemes focus sufficient preferred enabling pollinators self‐select diverse nutritious diet.

Bee attraction to flowers mediated by both quantity resources (the number available for exploration) quality (pollen nutritional value), but whether how bees prioritize these factors not well understood.

Abstract Wildflower habitats planted along field borders are a widely promoted strategy for supporting bees in agricultural landscapes. However, honeybees ( Apis mellifera ), which often stocked at high densities crop lands can compete with wild pollen and nectar, potentially limiting the successfulness of wildflower plantings diverse bee communities. Using weekly samples five study sites Northern California we assessed how plants pollinator‐friendly seed mixes varied their ability to provide abundant nutritious under intense honeybee competition. We quantified production, protein lipid content, end‐of‐day availability different plant species. also sampled visits flowers composition on bodies. these data, investigate nutritional quality abundance impacted native nutrition. Bees collected more (i.e. protein) from species high‐protein plants). as increased, diets declined. detected important interactions between plantings, such that, some taxa, there was no impact competition diet high‐nutrition plantings. Synthesis applications : Our reveals that reduce diets. From an applied conservation perspective, therefore recommend introductions natural areas be approached extreme caution. our results suggest flower could mitigate negative effects managed Where simultaneous support is key management objective, including populations.

We show that gardens provide 15% overall annual nectar landscapes Southwest UK, between 50% 95% during early spring late summer when supplies low. therefore reduce seasonal gaps experienced by bumblebees. Consistent with this pattern, bumblebee activity increased relative to summer.
