Metabolomics unveils the influence of dietary phytochemicals on residual pesticide concentrations in honey bees

Environment International, 2021
The losses of honey bee colonies and declines of other insect pollinators have been associated with negative effects of pesticides. Honey bees as well as other pollinators are nectar and pollen foragers and thus are exposed to an extensive range of ...

Bioecology and Domiciliation of the Alkali Bee, Hoplonomia westwoodi (Gribodo, 1894) (Hymenoptera: Halictidae: Nomiinae) from India

Sociobiology, 2022
We describe here nesting biology of Hoplonomia westwoodi, a common ground nesting solitary bee in India. A typical nest consisted of a straight main tunnel with the cells arranged horizontally at the end. Number of cells per nest ranged from 2 to 4 (x̄ =

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

Frontiers 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.

PLoS 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

The Movement of Western Honey Bees (Apis mellifera L.) Among U.S. States and Territories: History, Benefits, Risks, and Mitigation Strategies

Frontiers in Ecology and Evolution, 2022
Beekeeping is a cornerstone activity that has led to the human-mediated, global spread of western honey bees (Apis mellifera L.) outside their native range of Europe, western Asia, and Africa.

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

Insects, 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

Comparing levels of geitonogamous visitation by honey bees and other pollinators

Journal 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.

Unraveling Honey Bee–Varroa destructor Interaction: Multiple Factors Involved in Differential Resistance between Two Uruguayan Populations

Veterinary Sciences, 2020
The ectoparasite Varroa destructor is the greatest biotic threat of honey bees Apis mellifera in vast regions of the world. Recently, the study of natural mite-resistant populations has gained much interest to understand the action of natural selection ...

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

PLoS 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.

Introduced honey bees increase host plant abundance but decrease native bumble bee species richness and abundance

Ecosphere, 2022
Long‐term variation in the population density of introduced honey bees (Apis mellifera) has been shown to be associated with variations in floral traits in alpine lotus (Saussurea nigrescens).
