Genomic insights into neonicotinoid sensitivity in the solitary bee Osmia bicornis. [PDF]
The impact of pesticides on the health of bee pollinators is determined in part by the capacity of bee detoxification systems to convert these compounds to less toxic forms.

Peptidomic analysis of the venom of the solitary bee Xylocopa appendiculata circumvolans [PDF]
Background Among the hymenopteran insect venoms, those from social wasps and bees – such as honeybee, hornets and paper wasps – have been well documented.

The Supercooling Responses of the Solitary Bee Osmia excavata (Hymenoptera: Megachilidae) under the Biological Stress of Its Brood Parasite, Sapyga coma (Hymenoptera: Sapygidae) [PDF]
(1) Background: Many insects have evolved different strategies to adapt to subzero temperatures and parasites, but the supercooling response of pollinator populations under the brood parasitism pressure has not been sufficiently investigated. (2) Methods:

Solitary bee larvae modify bacterial diversity of pollen provisions in the stem-nesting bee, Osmia cornifrons (Megachilidae) [PDF]
Microbes, including diverse bacteria and fungi, play an important role in the health of both solitary and social bees. Among solitary bee species, in which larvae remain in a closed brood cell throughout development, experiments that modified or ...

Predation Cues in Solitary bee Nests. [PDF]
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).

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

Susceptibility of solitary bees to agrochemicals highlights gaps in bee risk assessment
Ground-nesting solitary bees are the most abundant bee species in the xeric areas of the world, but the effects of agrochemicals on them have been little studied. Herein, we evaluated the topical toxicity of an insecticide, a herbicide, and an essential oil on Mediterranean ground-nesting bees (Andrena impunctata, A. nigroolivacea, A.

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