Abstract Pollinators in agricultural landscapes are facing global decline and the main pressures include food scarcity pesticide usage. Although intensive poor habitats for wild pollinators, mass flowering crops may provide important resources, albeit monofloral short-term, which addition contain residues. We explored how landscape composition with a different proportion of oilseed rape (6%-65%) around Osmia bicornis nests affects floral diversity, contamination pesticides, energetic value provisions collected by bees as their offspring. The pollen from 28 taxa (6-15 per nest) were dominated Brassica napus (6.0-54.2%), Quercus (1.2-19.4%) Ranunculus (0.4-42.7%) found all 12 nests, but also Poaceae (1.2-59.9%, 11 nests) Acer (0.6-42%, 8 nests). Residues pesticides provisions, acetamiprid, azoxystrobine, boscalid, dimethoate being most frequently detected at concentrations up to 1.2, 198.4, 16.9 17.8 ng/g, respectively. Floral diversity not Pesticide Risk Index depended on structure. Moreover, decreased, increased diversity. Thus, even structurally simple diverse O. if nest is located close single resource-diverse patch. Both B. non-crop correlated concentrations.

Fungicides account for more than 35% of the global pesticide market and their use is predicted to increase in future. While fungicides are commonly applied during bloom when bees likely foraging on crops, whether real-world exposure these chemicals - alone or combination with other stressors constitutes a threat health still subject great uncertainty. The first step estimating risks understand how what extent exposed active ingredients. Here we review current knowledge that exists about experience field, link quantitative data acute chronic risk lethal endpoints honey (Apis mellifera). From 702 publications screened, 76 studies contained residue detections bee matrices, further 47 provided qualitative information range taxa through various routes. We compiled 90 metabolites have been detected honey, beebread, pollen, beeswax, bodies bees. posed by fungicide residues was estimated EPA Risk Quotient (RQ) approach. Based concentrations pollen/beebread, none reported exceeded levels concern (LOC) set regulatory agencies risk, while 3 12 European Food Safety Authority (EFSA) LOC wild bees, respectively. When considering all most include many broad-spectrum systemic fungicides, as well widely used contact chlorothalonil. In addition providing detailed overview frequency environment, identified important research gaps suggest future directions move towards comprehensive understanding mitigation including synergistic co-exposure pesticides pathogens.

Cultivation of mass flowering entomophilous crops benefits from the presence managed and wild pollinators, who visit flowers to forage on pollen nectar. However, management these typically includes application pesticides, which may pose a hazard for pollinators foraging in an agricultural environment. To determine levels potential exposure their concentration nectar need assessing, both within beyond target crop plants. We selected ten pesticide compounds one metabolite analysed occurrence (Brassica napus) plant (Rubus fruticosus agg.), was field edges. Nectar plants were collected five spring winter sown B. napus fields Ireland, tested residues, using QuEChERS Liquid Chromatography tandem spectrometry (LC-MS/MS). Pesticide residues detected Most detections with no recorded respective that year, but higher concentrations observed recently treated fields. Overall, more than plant, had highest mean residues. All matrices contaminated at least three compounds, most frequently fungicides. The common compound mixture comprised fungicides azoxystrobin, boscalid, neonicotinoid insecticide clothianidin, not applied Our results indicate persistent like neonicotinoids, should be continuously monitored fate toxicological evaluation mixtures identified present study performed, impacts insects exposed them.

Agricultural landscapes have changed substantially in recent decades, shifting from the dominance of small fields (S) with diverse cropping systems toward large-scale monoculture (L), where landscape heterogeneity disappears. In this study, artificial nests red mason bee, Osmia bicornis, were placed S and L types on perimeter oilseed rape representing different coverages (ORC, % land cover). The local structure around each nest was characterised within a 100, 200, 500, 1000 m radius using ORC 14 characteristics, which then reduced by non-metric multidimensional scaling (nMDS) to two axes: nMDS1 dataset primarily according fragmentation main crop, whereas nMDS2 captured prevalence more natural areas landscape.

Here, we analyzed the impacts both aspects heterogeneity role conditions pollinating insect communities two economically important mass-flowering crops across Europe. Methods Using a standardized approach, collected data five groups (honey bees, bumble other hover flies butterflies) eight oilseed rape apple orchard sites (in adjacent crop margins), European countries (128 total) encompassing four biogeographic regions, quantified habitat calculating relevant metrics for (proportion land-use types) (the aggregation isolation patches). Results We found that insects responded to climate parameters taxon- crop-specific ways. For example, was positively correlated with honey bee solitary fields, fly orchards. In sites, total all pollinators, bees decreased an increasing proportion orchards surrounding landscape. less-intensively managed habitats (i.e., woodland, grassland, meadows, hedgerows) influenced butterflies. Additionally, our showed daily annual temperature, as well precipitation seasonality, affects although, again, these appeared be or crop-specific.

Home gardening has a long history that started when humans became sedentary, being traditionally considered an accessible source of food and medicinal plants to treat common illnesses. With trends towards urbanization industrialization, particularly in the post-World War II period, importance home gardens as important spaces for growing reduced they began be increasingly seen decorative leisure spaces. However, awareness negative impacts agricultural intensification human health, quality, ecosystem resilience, biodiversity conservation motivated emergence new approaches concerning gardens.
