Diet and nutritional status during early adult life have immediate and persistent effects on queen bumble bees.

Conservation Physiology, 2019
Many insects sequester nutrients during developmentally programmed periods, which they metabolize during subsequent life history stages. During these periods, failure to store adequate nutrients can have persistent effects on fitness. Here, we examined a

Valorization of fruit pits from Prunus laurocerasus and Prunus cerasifera as agro‐food byproducts: Bioactive properties and safety assessment for potential food additive applications

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Food additives are widely used to extend the shelf life of foods and maintain their quality. In this study, the potential of Prunus laurocerasus and Prunus cerasifera fruit pits (endocarp and seed) as food additives was investigated in terms of cytotoxicity, antigenotoxicity, antioxidant activity, enzymatic anti‐browning, and urease

Colonies of Bumble Bees (Bombus impatiens) Produce Fewer Workers, Less Bee Biomass, and Have Smaller Mother Queens Following Fungicide Exposure

Insects, 2015
Bees provide vital pollination services to the majority of flowering plants in both natural and agricultural systems. Unfortunately, both native and managed bee populations are experiencing declines, threatening the persistence of these plants and crops.

Linking bacterial diversity to floral identity in the bumble bee pollen basket

Environmental DNA, 2021
Multitrophic interactions are ubiquitous in nature and form the basis of biodiversity. For example, bumble bees visit flowers to collect pollen, on which a variety of bacteria exist.

Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]

, 2017
For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

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.

Foxglove, Digitalis purpurea: An Eco-feast Plant for Bumble Bee Conservation in the Northwestern Himalayas

Sociobiology
Bumble bees (Bombus spp.) are key pollinators in Himalayan ecosystem, but habitat degradation and floral resource scarcity threaten their population. Foxglove, Digitalis purpurea, an introduced plant with deep corolla, is an important source of pollen ...

With a Great Story Comes Great Responsibility: Role of Narrative in Leadership Development

New Directions for Student Leadership, Volume 2025, Issue 185, Page 81-87, Spring 2025.
ABSTRACT Comic books reside uniquely within American culture. Historians have contended comics are more than just sequential artwork mixed with engaging stories, but rather, a framework by which the generations make sense of who they are. These stories are a reflection of cultural conscience; a lens through which we can view the world and a mirror ...

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

Agronomy, 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.

Bumble bees (Hymenoptera: Apidae: Bombus terrestris) collecting honeydew from the giant willow aphid (Hemiptera: Aphididae) [PDF]

Journal of Hymenoptera Research, 2019
Only rarely have bumble bees (Bombus) been observed collecting honeydew from aphids (Aphididae) feeding on phloem sap. This behavior may be rare because the percentage of sugar in honeydew egested from aphids is generally well below the sugar ...
