Diversity and abundance of solitary and primitively eusocial bees in an urban centre: a case study from Northampton (England) [PDF]
Journal of Insect Conservation, 2015 The apparent reduction of solitary and primitively eusocial bees populations has remained a huge concern over the past few decades and urbanisation is considered as one of the factors affecting bees at different scales depending on bee guild.

Ecotoxicology and Environmental Safety, 2023 Pesticide exposure is an important driver of bee declines. Laboratory toxicity tests provide baseline information on the potential effects of pesticides on bees, but current risk assessment schemes rely on one species, the highly social honey bee, Apis ...

Mitigating the Effects of Habitat Loss on Solitary Bees in Agricultural Ecosystems
Agriculture (Switzerland), 2020 Solitary bees and other wild pollinators provide an important ecosystem service which can benefit both the agricultural economy and the sustainability of many native ecosystems. Many solitary bees, however, are experiencing decreases in their populations

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

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

Neotropical bee microbiomes point to a fragmented social core and strong species-level effects
Microbiome, 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
Frontiers 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.
