Pesticide Contamination in Native North American Crops, Part II—Comparison of Flower, Honey Bee Workers, and Native Bee Residues in Lowbush Blueberry

open access: yesInsects
In lowbush blueberry fields, we conducted residue analysis comparing flowers, trapped pollen (honey bee and Osmia spp.), and collected bees (honey bee workers, bumble bee queens, and non-Bombus spp. wild native bees). The study was conducted from 2012 to

Effects of sacbrood virus on adult honey-bees

open access: yes, 1972
SUMMARY Much sacbrood virus accumulates in the brains of infected bees, especially of drones, without causing symptoms. However, infected individuals fly earlier in life than healthy bees and most infected foragers fail to collect pollen, as do bees ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

open access: yesInsect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Dietary modulation of gut microbiota and functional enzymes in savannah honey bees (Apis mellifera scutellata Lepeletier)

open access: yesApplied Microbiology and Biotechnology
Honey bees gather pollen from flowering plants, using it as a vital protein source and, in turn, acquire pollen-associated microbes that interact with their existing gut microbiota.

Declines of managed honey bees and beekeepers in Europe

open access: yes, 2009
Growing evidence indicates that European managed honey bees are in decline, but information for Europe remains patchy and localized. Here we compile data from 18 European countries to assess trends in the number of honey bee colonies and beekeepers ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

open access: yesInsect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

A Spatial Look at Negative Externalities in Agricultural Landscapes: Seedless Mandarins and Honey Bee Pollination in California

open access: yes
When honey bees transport pollen across citrus orchards they can increase the number of seeds in varieties that remain seedless otherwise. An increase in seeds diminishes the market value of the fruit creating an externality between seedless growers and ...

US Farm Bill in 2025: Ad Hoc Assistance becomes an Expanded Multi‐Year Safety Net Loi agricole américaine de 2025 : l'aide ponctuelle devient un filet de sécurité pluriannuel élargi US Farm Bill in 2025: Ad‐hoc‐Beihilfen werden zu einem erweiterten mehrjährigen Sicherheitsnetz

open access: yesEuroChoices, EarlyView.
Summary The 2025 US farm bill converts ad hoc farm assistance since 2018 into a projected US$ 62 billion farm safety net expansion within multi‐year legislation. Usually stand‐alone with strong bipartisan support, the 2025 edition is largely provisions in a far‐reaching, partisan budget law. The farm safety net is expanded by cutting food assistance to

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

open access: yesIntegrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Using honey in wound care

open access: yes, 2006
Honey is primarily a herbal product with some modifications that are made by the bees that process the nectar or sap collected from the plants to store as honey. The types of phytochemicals present in a honey depend on the plant source of the honey.
