Contact toxicity of three insecticides for use in tier I pesticide risk assessments with Megachile rotundata (Hymenoptera: Megachilidae) [PDF]

open access: yesPeerJ, 2021
The current pesticide risk assessment paradigm may not adequately protect solitary bees as it focuses primarily on the honey bee (Apis mellifera). The alfalfa leafcutting bee (Megachile rotundata) is a potential surrogate species for use in pesticide ...

Deformed wing virus prevalence in solitary bees put to the test: an experimental transmission study

open access: yesFrontiers in Ecology and Evolution, 2023
Virus spillover from managed to unmanaged bees and vice versa may be one mechanism driving colony losses of the former and declines of the latter. There is clear evidence that the ubiquitous Deformed wing virus (DWV) is a major driver of honey bee (Apis ...

Neotropical bee microbiomes point to a fragmented social core and strong species-level effects

open access: yesMicrobiome, 2023
Background Individuals that band together create new ecological opportunities for microorganisms. In vertical transmission, theory predicts a conserved microbiota within lineages, especially social bees. Bees exhibit solitary to social behavior among and/

Phenological mismatches and the demography of solitary bees

open access: yesProceedings of the Royal Society B: Biological Sciences, 2023
Species respond idiosyncratically to environmental variation, which may generate phenological mismatches. We assess the consequences of such mismatches for solitary bees. During 9 years, we studied flowering phenology and nesting phenology and demography of five wood-nesting solitary bee species representing a broad gradient of specialization ...

The contributions of flower strips to wild bee conservation in agricultural landscapes can be predicted using pollinator habitat suitability models

open access: yesEcological Solutions and Evidence, 2023
Sowing flower strips along field edges is a widely adopted method for conserving pollinating insects in agricultural landscapes. To maximize the effect of flower strips given limited resources, we need spatially explicit tools that can prioritize their ...

Venom profile of the European carpenter bee Xylocopa violacea: Evolutionary and applied considerations on its toxin components

open access: yesToxicon: X, 2022
Modern venomics is increasing its focus on hymenopterans such as honeybees, bumblebees, parasitoid wasps, ants and true wasps. However solitary bees remain understudied in comparison and the few available venom studies focus on short melittin-like ...

The Impact of Different Biotopes and Management Practices on the Burden of Parasites in Artificial Nests of Osmia spp. (Megachilidae) Bees

open access: yesDiversity, 2022
The decline in pollinator insect abundance and diversity is increasing on a global scale. Major threats are the byproducts of numerous negative environmental pressures acting individually or in combination.

Post-embryonic Development of the Circadian Clock Seems to Correlate With Social Life Style in Bees

open access: yesFrontiers in Cell and Developmental Biology, 2020
Social life style can influence many aspects of an animal’s daily life, but it has not yet been clarified, whether development of the circadian clock in social and solitary living bees differs.

Ascosphaera callicarpa, a new species of bee-loving fungus, with a key to the genus for Europe. [PDF]

open access: yesPLoS ONE, 2013
We studied the bee specialist fungus Ascosphaera in wild solitary bees to investigate the diversity of the genus in nature and the ecology of these fungi with their bee hosts.

Widespread occurrence of honey bee pathogens in solitary bees [PDF]

open access: yesJournal of Invertebrate Pathology, 2014
Solitary bees and honey bees from a neighbouring apiary were screened for a broad set of putative pathogens including protists, fungi, spiroplasmas and viruses. Most sampled bees appeared to be infected with multiple parasites. Interestingly, viruses exclusively known from honey bees such as Apis mellifera Filamentous Virus and Varroa destructor Macula-
