Transient exposure to low levels of insecticide affects metabolic networks of honeybee larvae [PDF]

open access: yes, 2013
The survival of a species depends on its capacity to adjust to changing environmental conditions, and new stressors. Such new, anthropogenic stressors include the neonicotinoid class of crop-protecting agents, which have been implicated in the population

Relationships between phenotype, mating behavior, and fitness of queens in the ant Lasius niger [PDF]

open access: yes, 2004
Considerable attention has focused on why females of many species mate with several males. For social hymenopteran insects, efforts have primarily concentrated on determining whether multiple mating increases colony performance due to the increased ...

Evaluation of Antioxidant and Enzyme Inhibition Properties of Siran Propolis: Correlations With Phenolic Content Determined by LC–MS/MS

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
The ethanolic extract of Şiran propolis exhibited strong antioxidant activity and inhibited α‐glycosidase, AChE, and human carbonic anhydrase isozymes I and II. High levels of phenolic acids, especially p‐coumaric and ferulic acids, correlated with its bioactivity.

Effects of Nosema ceranae and thiametoxam in Apis mellifera: A comparative study in Africanized and Carniolan honey bees [PDF]

open access: yesChemosphere, 2016
Multiple stressors, such as chemicals and pathogens, are likely to be detrimental for the health and lifespan of Apis mellifera, a bee species frequently exposed to both factors in the field and inside hives. The main objective of the present study was to evaluate comparatively the health of Carniolan and Africanized honey bees (AHB) co-exposed to ...

Patterns of single nucleotide polymorphism (snp) variation: further insights into the complex history of the iberian honeybee [PDF]

open access: yes, 2013
The Iberian Peninsula harbours the greatest honeybee genetic diversity and complexity in Europe. The challenge of deciphering the mechanisms underlying such complexity has led to numerous morphological and molecular marker-based surveys of the Iberian ...

Anomalies and asymmetry of wing venation pattern in Carniolan and Egyptian bee populations in Egypt [PDF]

open access: yesEgyptian Academic Journal of Biological Sciences. A, Entomology, 2011
The presence of unusual wing venation and asymmetry of the forewing in Carniolan and Egyptian honeybees in Egypt were recorded. The present study indicates that, Carniolan bees had higher rate of unusual veins than the Egyptian bees. The frequency of adventitious veins was much higher than incomplete veins, and the marginal cell had the highest ...
