Oocyte size, egg index, and body lipid content in relation to body size in the solitary bee Megachile rotundata [PDF]

open access: yesPeerJ, 2014
Females of solitary, nest-provisioning bees have relatively low fecundity, but produce large eggs as part of their overall strategy of investing substantially in each offspring.

Endothermy and thermoregulation in solitary bees

open access: green, 1990
This thesis examines the roles of endothermy and body size in the thermal biology of solitary bees (Hymenoptera: Apoidea) within the species Anthophora plumipes (Anthophoridae) Amegilla sapiens (Anthophoridae) and Creightonellafrontalis (Megachilidae), within the genus Anthophora, and over the Apoidea as a whole.

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 ...

Larval exposure to field-realistic concentrations of clothianidin has no effect on development rate, over-winter survival or adult metabolic rate in a solitary bee, Osmia bicornis [PDF]

open access: gold, 2017
There is widespread concern regarding the effects of agro-chemical exposure on bee health, of which neonicotinoids, systemic insecticides detected in the pollen and nectar of both crops and wildflowers, have been the most strongly debated.

Sensitivity to imidacloprid insecticide varies among some social and solitary bee species of agricultural value.

open access: yesPLoS ONE, 2023
Pollinator health risks from long-lasting neonicotinoid insecticides like imidacloprid has primarily focused on commercially managed, cavity-nesting bees in the genera Apis, Bombus, and Osmia.

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/

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.

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 ...

Predation Cues in Solitary bee Nests [PDF]

open access: yesJournal of Insect Behavior, 2017
Predation at the nesting site can significantly affect solitary bees' reproductive success. We tested female red mason bees' (Osmia bicornis L.) acceptance of potential nesting sites, some of which were marked with cues coming from predated conspecifics (crushed bees) or from a predator itself (rodent excreta).
