“…Key foraging resources for pollinators are provided by different habitats to various degrees (Cole et al, 2017), and resource shortages may occur in agricultural landscapes (Jachula, Denisow, & Wrzesien, 2018), resulting in a decrease in bee survival (Requier, Odoux, Henry, & Bretagnolle, 2017). To properly manage such habitats for bees, the specific nutritional needs of the bee species of interest should be understood.…”

1. Bee-friendly plants are defined by the quantity of food they produce and the visitation rates of adult insects foraging for nectar. However, it is pollen nutritional quality that enables proper larval development of bees, affecting their populations. Not all plants produce pollen that satisfies the nutritional requirements of bee larvae, and we lack an understanding of how different plant pollens impact bee nutritional demands. This study examined whether nutritionally desirable key plant species may promote wild bee larval development, which is essential if the population is to thrive.2. The generalist solitary mason bee Osmia bicornis L. was used as a model species to examine differences between bee larva nutritional demand and host plant nutrient supply; an ecological stoichiometry framework was applied. The stoichiometric ratios of 12 elements were investigated in bee bodies and cocoons (reflecting nutritional demand) and in the pollen supplied by the mother (nutritional supply; N = 15 × 2 sexes). Similarly, the stoichiometry of 62 pollen taxa, including native, alien, and garden plants and crops, was compared with the bee demand based on the literature.3. Compared to males, females had higher demands for P, Cu and Zn and were supplied with pollen richer in these elements. Therefore, when collecting pollen for their progeny, Osmia provides daughters and sons with different pollen mixtures, reflecting sex-specific nutritional demand. 4. Bees may be limited by the availability of P, Na, Mn, Mg, K, Fe, Ca, Zn and Cu, with high taxonomic variability in their concentrations in pollen. Female fitness may be particularly related to a high proportion of P in the diet. Synthesis and applications.Access to key plant species that allow nutritionally balanced larval diets may be essential for bee development, whether food is gathered intentionally or randomly. Such plant species-and not only those rich in nectar and pollen-should be promoted in wild bee conservation efforts, including planting flower strips and hedgerows. Bee-friendly plants should not be defined and planted solely based on the quantities of food they produce and on the visitation rates of adult insects foraging for energy.

“…Under the climatic conditions in Poland, P. caeruleum bloomed in late spring. This period is considered to be critical for the survival of honey bee colonies because in urban-adjacent agricultural areas, seasonal gaps in food resources were recorded [19,52,53]. Contrasting weather patterns occurred between the study seasons.…”

“…Over the last decades, insect pollinator species richness and abundance have declined [10][11][12][13]. Although this phenomenon is complex, several reasons for pollinator decrease have been identified: pathogens and diseases [14,15], intensification of agricultural production and application of pesticides [16,17], habitat fragmentation [18], and the shortage of floral food resources [19][20][21]. One of the initiatives suggested for mitigating pollinator failure is improvement of floral food resources, both in agricultural [19,22,23] and urban areas [24][25][26].…”

Mosaic structure of urban green areas is regarded as favorable for pollinating insects. Ornamental plants can provide food resources to pollinators and may thus be used to create pollinator-friendly habitats. However, detailed data on forage quantity and quality is required for the selection of the most valuable plant species. In this paper, blooming biology, pollen production, and insect visitors of two forms (blue-flower and white-flower) of Polemonium caeruleum were studied in the period of 2012–2014 in Lublin, SE Poland. Both forms bloomed from mid-May until mid-June. The average mass of pollen produced in a single flower was 1.57 mg and 1.39 mg in blue-flower and white-flower forms, respectively. On average, the blue-flower form produced 7.74 g of pollen/m2, while the white-flower form yielded 6.54 g of pollen/m2. Both forms attracted mainly honey bees and solitary bees. Polemonium caeruleum can be considered a good source of pollen for honey bees and wild insect pollinators and should be propagated in urban pollinator-friendly arrangements.

The statistics from Europe and the USA have proven a high risk for skin diseases associated with plant contact. Therefore, plant-induced dermatitis is of increasing attention in dermatology. The focus of this paper was to present the current knowledge on aspects of contact allergy related to Asteraceae (Compositae) species. The Asteraceae family is one of the largest in the world with members across all continents. The PubMed/Medline databases have been searched. The Asteraceae representatives consist of diverse secondary metabolites, which exhibit various advantageous effects in humans. In particular, sesquiterpene lactones (SLs) may cause sensitization resulting in skin irritation and inflammation. In this study, we tried to reveal the allergenic potential of several Asteraceae species. The Asteraceae-related allergy symptoms involve eczema, hay fever, asthma, or even anaphylaxis. Furthermore, the evidence of severe cross-reactivity with food and pollen allergens (PFS) in patients sensitive to Asteraceae allergens have been announced. Further identification and characterization of secondary metabolites and possible allergens in Asteraceae are necessary for the better understanding of Asteraceae-related immune response. The Asteraceae allergy screening panel (the SL mix and the Compositae mix of five plant species) is a promising tool to improve allergy diagnostics and therapy.
