Chemical Stimulants and Stressors Impact the Outcome of Virus Infection and Immune Gene Expression in Honey Bees (Apis mellifera)

open access: yesFrontiers in Immunology, 2021
Western honey bees (Apis mellifera) are ecologically, agriculturally, and economically important plant pollinators. High average annual losses of honey bee colonies in the US have been partially attributed to agrochemical exposure and virus infections ...

Tropilaelaps mercedesae parasitism changes behavior and gene expression in honey bee workers.

open access: yesPLoS Pathogens, 2021
Tropilaelaps mercedesae is one of the most problematic honey bee parasites and has become more threatening to the beekeeping industry. Tropilaelaps can easily parasitize immature honey bees (larvae and pupae) and have both lethal and sublethal effects on

Comparing levels of geitonogamous visitation by honey bees and other pollinators

open access: yesJournal of Pollination Ecology, 2023
Geitonogamy, the transfer of pollen from one flower to another on the same plant, is often the primary means of self-pollination in flowering plants.

Honey bees (Apis mellifera) modify plant-pollinator network structure, but do not alter wild species' interactions.

open access: yesPLoS ONE, 2023
Honey bees (Apis mellifera) are widely used for honey production and crop pollination, raising concern for wild pollinators, as honey bees may compete with wild pollinators for floral resources.

B-Vitamins Influence the Consumption of Macronutrients in Honey Bees

open access: yesFrontiers in Sustainable Food Systems, 2022
Insects require dietary sources of B-vitamins, but relatively little is known about whether they regulate B-vitamin intake in the same way they regulate other nutrients.

Honey Bee Nutrition

open access: yesVeterinary Clinics of North America: Food Animal Practice, 2021
Optimal nutrition is crucial for honey bee colony growth and robust immune systems. Honey bee nutrition is complex and depends on the floral composition of the landscape. Foraging behavior of honey bees depends on both colony environment and external environment.

Chronic Cadmium Exposure Induces Impaired Olfactory Learning and Altered Brain Gene Expression in Honey Bees (Apis mellifera)

open access: yesInsects, 2022
The honey bee (Apis mellifera) plays vital ecological roles in the pollination of crops and the maintenance of ecological balance, and adult honey bees may be exposed to exogenous chemicals including heavy metals during their foraging activities. Cadmium

Visual diagnosis of the Varroa destructor parasitic mite in honeybees using object detector techniques [PDF]

open access: yesSensors, 21-8 (2021), 2764-2780, 2021
The Varroa destructor mite is one of the most dangerous Honey Bee (Apis mellifera) parasites worldwide and the bee colonies have to be regularly monitored in order to control its spread. Here we present an object detector based method for health state monitoring of bee colonies. This method has the potential for online measurement and processing.

Honey Bee Viruses [PDF]

open access: yes, 2007
Viruses are significant threats to the health and well-being of the honey bee, Apis mellifera. To alleviate the threats posed by these invasive organisms, a better understanding of bee viral infections will be of crucial importance in developing effective and environmentally benign disease control strategies. Although knowledge of honey bee viruses has

Analysis of Pollination Services Provided by Wild and Managed Bees (Apoidea) in Wild Blueberry (Vaccinium angustifolium Aiton) Production in Maine, USA, with a Literature Review

open access: yesAgronomy, 2020
Maine is the largest producer of wild blueberry (Vaccinium angustifolium Aiton) in the United States. Pollination comes from combinations of honey bees (Apis mellifera (L.)), commercial bumble bees (Bombus impatiens Cresson), and wild bees.
