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 ...

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.

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 ...

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.

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).

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 ...

Plant species richness and sunlight exposure increase pollinator attraction to pollinator gardens

open access: yesEcosphere, 2022
Evidence documenting the decline of insect populations is accumulating. Efforts have increased to mitigate pollinator losses by establishing gardens to support pollinator diversity.
