Laboratory acute contact toxicity test with the leafcutter bee Megachile rotundata [PDF]

open access: yesJulius-Kühn-Archiv, 2020
So far little is known about the toxicity of Plant Protection Products (PPPs) to solitary bees other than Osmia spp. as well as the inter- and intra-species sensitivity differences of honey bees and solitary bees.

The Bee Brick: building habitat for solitary bees [PDF]

open access: yes, 2023
This article describes the process of designing the Bee Brick - a novel solution for integrating solitary bee habitats within buildings. Of the 250 species of bee in the UK, 90% are solitary bees of which 5% nest in cavities.

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 ...

Managed honey bee colony losses in Canada, China, Europe, Israel and Turkey, for the winters of 2008-9 and 1009-10 [PDF]

open access: yes, 2012
In 2008 the COLOSS network was formed by honey bee experts from Europe and the USA. The primary objectives set by this scientific network were to explain and to prevent large scale losses of honey bee (Apis mellifera) colonies.

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/

Solitary-wave solutions of the Degasperis-Procesi equation by means of the homotopy analysis method [PDF]

open access: yes, 2010
The homotopy analysis method is applied to the Degasperis-Procesi equation in order to find analytic approximations to the known exact solitary-wave solutions for the solitary peakon wave and the family of solitary smooth-hump waves.

Sublethal neonicotinoid insecticide exposure reduces solitary bee reproductive success [PDF]

open access: yes, 2014
1.Pollinating insects provide crucial and economically important ecosystem services to crops and wild plants, but pollinators, particularly bees, are globally declining as a result of various driving factors, including the prevalent use of pesticides for

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 ...
