Humans versus dogs; a comparison of methods for the detection of bumble bee nests
, 2012 This study investigates alternative approaches to locating bumble bee nests for scientific research. We present results from three trials designed to assess: 1. The comparative efficiency of two detection dogs; 2.

Evaluation of the FERA study on bumble bees and consideration of its potential impact on the EFSA conclusions on neonicotinoids [PDF]
EFSA Journal, 2013 The European Food Safety Authority was requested to clarify whether the new publication on the effects of neonicotinoid seed treatments on bumble bee colonies under field conditions (March, 2013; Thompson et al.) has an impact on the EFSA Conclusions on ...

A landscape-scale study of bumble bee foraging range and constancy, using harmonic radar
, 1999 1. Bumble bees play a vital role in the pollination of many crops and wild flowers, and plans for their conservation require a knowledge of the dynamics and spatial scale of their foraging flights, which are, at present, poorly understood. 2.

Honey bees exhibit greater patch fidelity than bumble bees when foraging in a common environment
Ecosphere, 2023 Animals commonly exhibit a tendency to return to previously visited locations. Such tendency is manifested at different scales, for example, fidelity to a site or fidelity to a specific patch within a site.

First detection of the larval chalkbrood disease pathogen Ascosphaera apis (Ascomycota: Eurotiomycetes: Ascosphaerales) in adult bumble bees. [PDF]
PLoS ONE, 2015 Fungi in the genus Ascosphaera (Ascomycota: Eurotiomycetes: Ascosphaerales) cause chalkbrood disease in larvae of bees. Here, we report the first-ever detection of the fungus in adult bumble bees that were raised in captivity for studies on colony ...

Cross-infectivity of honey and bumble bee-associated parasites across three bee families
Parasitology, 2020 Recent declines of wild pollinators and infections in honey, bumble and other bee species have raised concerns about pathogen spillover from managed honey and bumble bees to other pollinators.

Neonicotinoid pesticide reduces bumble bee colony growth and queen production
, 2012 Growing evidence for declines in bee populations has caused great concern because of the valuable ecosystem services they provide. Neonicotinoid insecticides have been implicated in these declines because they occur at trace levels in the nectar and ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

Pest Management Science, EarlyView.SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.
