Volatiles of foraging honeybees Apis mellifera (Hymenoptera: Apidae) and their potential role as semiochemicals
Which compounds occurs on the cuticle of honeybee workers are analysed and which might be used as kairomones by females of the European beewolf Philanthus triangulum to identify their prey are analyzed.
Chemical and behavioural strategies along the spectrum of host specificity in ant-associated silverfish
It is found that behaviour that seems to facilitate the integration in the host colony was more pronounced in host specialist silverfish, irrespective of their degree of host specificity.
Prisoners receive food fit for a queen: honeybees feed small hive beetles protein-rich glandular secretions through trophallaxis
It is shown that small hive beetles successfully induce worker bees to feed them the protein-rich secretions of their hypopharyngeal glands during trophallaxis, and that females are more successful than males in inducing the transfer of these protein- rich secretions.
From Consciousness to Brain-Sign: a Neurobiological Reconstruction
By replacing the prescientific notion of consciousness, the theory of brain-sign can enable a scientific path for brain science.
Pests, parasitoids, and predators: Can they degrade the sociality of a honeybee colony, and be assessed via acoustically monitored systems?
The nonlethal effects of insect invaders and mites on social behavior of in-hive honeybee colonies and the acoustic emissions produced during confrontations with insect invaders are addressed.
Natural biocide disrupts nestmate recognition in honeybees
The results demonstrated that exposed bees have altered cuticular hydrocarbons and are more easily accepted into foreign colonies than controls and the acceptance of chemically unrecognizable fungus-exposed foragers could therefore favour forager drift and disease spread across colonies.
Kilka słów na temat antycznych metod leczenia chorób pszczół
Ancient authors knew at least a few possible causes of the diseases of bees, described symptoms and were trying to suggest a cure, but deeper evaluation of their writings leads to a conclusion, that their knowledge was somewhat obsolete and therefore a fully successful treatments couldn’t be developed in the time they lived.
Cuticular fatty acids of Galleria mellonella (Lepidoptera) inhibit fungal enzymatic activities of pathogenic Conidiobolus coronatus
Differences in the hydrolysis of cuticles taken from larvae, pupae and adults (thorax and wings), by C. coronatus enzymes might be responsible for the varied efficiency of fungal enzymes in degrading larval, pupal and adult cuticles.


Genetic Study of Aggressiveness of two Subspecies of Apis Mellifera in Brazil 1. Some Tests to Measure Aggressiveness
Five tests based on the use of small leather balls, kept in motion just outside the hive entrance, were used to evaluate the relative aggressiveness of Italian and Africanized bees in Brazil and showed that the latter were significantly more aggressive.
Semiochemical basis of the retinue response to queen honey bees
It is reported that the mandibular-gland-based retinue response is mediated by five semiochemicals, each component is weakly active alone, but the complete blend imparts activity equivalent to HQMC extract at a level as low as 10–7 of that present in a queen.
The tooting and quacking vibration signals of honeybee queens: a quantitative analysis
A comparison of the threshold, emission level, and attenuation with distance, suggests that these and other vibration signals are used by honey bees only for local communication within a restricted area of the comb.
Conditioning honeybees to discriminate between heritable odors from full and half sisters
It is demonstrated that workers are able to discriminate between the odors from groups of 20 individuals only if the groups represent individuals from different patrilines, and heritable variation in the production of volatile odors by worker honeybees at a level that can be detected by the workers.

By using radioactive tracer (32P) it could be shown that the beetles participate parasitically in the ants food exchange in the nests of Formica and in those of Myrmica, and this interest in adoption is induced in ants by a secretion from the unicellular glands along the margins of the abdominal tergites.
Sound and vibrational signals in the dance language of the honeybee, Apis mellifera
Sound and vibrational signals exchanged by honeybees during the performance of wagging dances were simultaneously recorded by means of a microphone and a laser vibrometer to support the assumption that the begging signals are generated with the flight muscles.
