Solitary Bees

Scientific American, 1984
For most people the beehive and the intricate social organization of the honeybees that populate it are the hallmark of bee life. In reality more than 85 percent of the some 20,000 bee species are not social but solitary. Each female independently mates, makes her own nest of about 10 brood cells, stocks the cells with food for the young, lays an egg ...

Solitary Bees Facing Climate Change

Sociobiology
Solitary bees comprise over 15,000 species. They represent the vast majority of bees on earth (>77%), but they are less studied than the social species.

Effects of heat shocks, heat waves, and sustained warming on solitary bees

Frontiers in Bee Science
Along with higher average temperatures, global climate change is expected to lead to more frequent and intense extreme heat events, and these different types of warming are likely to differ in their effects on bees. Although solitary bees comprise >75%

‘Focal species’ – can this well-known concept in higher-tier risk assessments be an appropriate approach for solitary bees?

Julius-Kühn-Archiv, 2018
Bumble bees and solitary bees have to be considered in addition to honey bees regarding environmental pollinator risk assessments. For solitary bees it is proposed to use Osmia cornuta (LATR., 1805) or O. bicornis (L., 1758) as test organisms.

Positive Correlation between Pesticide Consumption and Longevity in Solitary Bees: Are We Overlooking Fitness Trade-Offs? [PDF]

Insects, 2020
The ubiquitous use of pesticides is one major driver for the current loss of biodiversity, and the common practice of simultaneously applying multiple agrochemicals may further contribute.

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 ...

Not every sperm counts: Male fertility in solitary bees, Osmia cornuta. [PDF]

PLoS One, 2019
Reproductive strategies can act as strong selective forces on reproductive traits of male insects, resulting in species-specific variation in sperm quantity and viability. For solitary bees, basic measures of sperm quantity and viability are scarce. Here

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

PLoS 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.
