Interactions between prairie dogs and arthropods in grassland ecosystems: a review and research gaps

open access: yesWildlife Biology, EarlyView.
Prairie dogs (Cynomys spp.) are an important component of grassland ecosystems of North America where they can alter vegetation composition/structure and physical attributes of grassland habitats through their feeding and burrowing behavior. Impacts of prairie dog presence on many wildlife and plant taxa have been widely studied but research on prairie

Genetic and Transcriptomic Basis of Enhanced Nectar and Resin Foraging in Honey Bees

open access: yesAgriculture
The collection of honey and propolis is crucial for the nutrition and health of honey bee colonies. In this study, Apis mellifera with high productivity for both honey and propolis (MJ) was developed through long-term selective breeding using Apis ...

Uneven Culturable Yeast Communities Harbored by Two Sympatric Stingless Bee Species: Scaptotrigona depilis and Tetragona clavipes

open access: yesYeast, EarlyView.
To explore the yeast diversity associated with Brazilian stingless bees, we collected samples from bees and their provisions. Sympatric bee species harbor distinct yeast communities, providing insights into bees' foraging choices. Moreover, these communities are dominated by specific taxa with similar metabolic profiles.

Evolution of queen pheromone receptor tuning in four honeybee species (Hymenoptera, Apidae, Apis)

open access: yesiScience
Summary: Honeybees (genus: Apis) use a plethora of pheromones for intraspecific communication. The primary compound produced by the queen’s mandibular glands, 9-ODA, is involved in mating in all Apis species. It is the ligand of the most highly expressed

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

G‐space versus E‐space: Are hornets (Hymenoptera: Vespidae) at equilibrium with honeybees in Asia?

open access: yesEcology and Evolution
This study delves into the concept of niche conservatism (NC) and its implications for how hornets (Hymenoptera: Vespidae) and honeybees respond to climate change.

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Characterization of the dynamic microbiome evolution across thrips species

open access: yesInsect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

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.
