Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1061-1071, September 2026.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

Microbial communities of three sympatric Australian stingless bee species. [PDF]

PLoS ONE, 2014
Bacterial symbionts of insects have received increasing attention due to their prominent role in nutrient acquisition and defense. In social bees, symbiotic bacteria can maintain colony homeostasis and fitness, and the loss or alteration of the bacterial

Projected Climate‐Suitable Area for Apis mellifera (Apidae) and Its Spatial Overlap With a Mining Tailings Footprint in South‐East Brazil

Journal of Applied Entomology, Volume 150, Issue 8, Page 1017-1024, September 2026.
ABSTRACT Climate change and environmental disasters can jointly impact species distributions and ecosystem stability, including pollinators and the resources they rely on. We used occurrence and climate data to predict the distribution of Apis mellifera in the Doce River Basin, south‐east Brazil, under baseline and future scenarios (2050).

Chemical Composition and Biological Activities of Geopropolis From Four Melipona Species From the Brazilian Atlantic Forest

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Geopropolis from four Melipona species collected in the Brazilian Atlantic Forest during the dry and rainy seasons was chemically characterized by ESI(‐)‐FT‐ICR MS and evaluated for antioxidant, anti‐inflammatory, and antifungal activities, demonstrating species‐ and season‐dependent variation in its chemical composition and biological properties ...

Stingless bee nesting biology

, 2006
Stingless bees diverged since the Cretaceous, have 50 times more species than Apis, and are both distinctive and diverse. Nesting is capitulated by 30 variables but most do not define clades.

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.
