The bumble bees (Hymenoptera: Apidae: Bombus) of Arkansas, fifty years later [PDF]
, 2015 Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking. In the present study, contemporary data

AutoPollS: A tool for automated monitoring of pollinators using deep learning
Methods in Ecology and Evolution, EarlyView.Abstract Deep learning and computer vision hold enormous potential for automated monitoring of biodiversity, including pollinators and other insects. Efficient, scalable monitoring of insect pollinators is crucial given pollinators' role in supporting biodiversity and agricultural productivity amidst declining pollinator populations.

Bumble bee nest thermoregulation: a field study
Journal of Apicultural Research, 2023 Careful control of brood temperature is important for successful colony development in social insects. Six bumble bee colonies of six common Central European species (B. hypnorum, B. hortorum, B. argillaceus, B. pascuorum, B. humilis, B. sylvarum) were continuously monitored for several weeks.

Coinvasional disruptions to island pollinator networks
Conservation Biology, EarlyView.Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Review of the methods to determine the hazard and toxicity of pesticides to bumblebees [PDF]
, 2001 Methods to determine the impact of pesticides on bumblebees are described. They are classified into laboratory tests to determine the acute toxicity and the hazard to bumblebees, (semi) field tests, and brood tests.

What currency do bumble bees maximize? [PDF]
PLoS ONE, 2010 In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency.

Local influence of floral resource attributes on urban bumble bee foraging activity
Frontiers in Sustainable Cities, 2023 IntroductionUrbanization diminishes the extent of uncompacted, exposed soil and the coverage of wild plant species, yet still supports diverse pollinator communities when their habitat is maintained within the built environment.

Honey bee-collected pollen is a potential source of Ascosphaera apis infection in managed bumble bees [PDF]
, 2019 The trade of bumble bees started in the early nineties for pollinator-dependent greenhouse plants. Nowadays, its rearing and transport have received public attention, since managed bees can transfer pathogens to wild bee populations.

Ecological Entomology, EarlyView.Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.
