Competição entre abelhas durante forrageamento em Schefflera arboricola (Hayata).

Bioscience Journal, 2007
Schefflera arboricola (Hayata) Merr (Araliaceae) é uma planta exótica, porém amplamente cultivada no Brasil para ornamentação. Devido à abundância de flores que produz, esta árvore é altamente atrativa para abelhas Apis mellifera, bem como para diversos ...

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

PLANTS, PEOPLE, PLANET, EarlyView.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

A strong immune response in young adult honeybees masks their increased susceptibility to infection compared to older bees [PDF]

, 2012
Honeybees, Apis mellifera, show age-related division of labor in which young adults perform maintenance ("housekeeping") tasks inside the colony before switching to outside foraging at approximately 23 days old. Disease resistance is an important feature

An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

Pest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]

, 2013
The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.

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

iScience
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

Pesticide use in integrated pest and pollinator management framework to protect pollinator health

Pest Management Science, Volume 81, Issue 4, Page 1691-1696, April 2025.
Integrated pest management (IPM) emphasizes non‐chemical methods, with pesticides as a last resort, while integrated pest and pollinator management (IPPM) integrates pollinator health into pest control strategies. Abstract Agricultural pesticides have historically been a critical tool in controlling pests and diseases, preventing widespread suffering ...

Assessing the role of dispersed floralresources for managed bees in providingsupporting ecosystem services for croppollination [PDF]

, 2018
Most pollination ecosystem services studies have focussed on wild pollinators and their dependence on natural floral resources adjacent to crop fields. However, managed pollinators depend on a mixture of floral resources that are spatially separated from

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

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

Ecology 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.
