Amplitude de nicho e similaridade no uso de recursos florais por abelhas eussociais em uma área de Cerrado

open access: yesBioscience Journal, 2007
A identificação das espécies de abelhas e suas relações com as plantas são importantes para conhecer os polinizadores e traçar estratégias de exploração racional de recursos naturais.

Local and landscape features of urban fragments determine the occurrence of stingless bees As características locais e paisagísticas dos fragmentos urbanos determinam a ocorrência de uma espécie de abelhas sem ferrão

open access: yesInsect Conservation and Diversity, EarlyView.
Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.

Varroa destructor detection on honey bees using hyperspectral imagery [PDF]

open access: yesarXiv
Hyperspectral (HS) imagery in agriculture is becoming increasingly common. These images have the advantage of higher spectral resolution. Advanced spectral processing techniques are required to unlock the information potential in these HS images. The present paper introduces a method rooted in multivariate statistics designed to detect parasitic Varroa

Localised patterns of wild bee abundance indicate woodlands play multiple roles in supporting farmland populations

open access: yesInsect Conservation and Diversity, EarlyView.
Across 12 farmland sites, we deployed wild bee traps in deciduous woodland canopies and understories, and in an open habitat (at field margins) before and after canopy closure. Post‐canopy closure, understory activity (relative to field margins) generally decreased, but higher temperatures may have increased its likelihood.

ApisTox: a new benchmark dataset for the classification of small molecules toxicity on honey bees [PDF]

open access: yesarXiv
The global decline in bee populations poses significant risks to agriculture, biodiversity, and environmental stability. To bridge the gap in existing data, we introduce ApisTox, a comprehensive dataset focusing on the toxicity of pesticides to honey bees (Apis mellifera).

Formulation and evaluation of alternative to beeswax for vegan lipsticks

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Characterization of a cosmetic ingredient as a vegan alternative to beeswax. Investigation of binary oil–wax systems for cosmetic applications. Development of a predictive strategy for the formulation of vegan stick cosmetics. Abstract Honeybees' success is strictly linked to the chemical and application properties of their products: honey, beeswax (BW)

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
