Inhibitory conditioning in honeybees
The Quarterly Journal of Experimental Psychology Section B, 2003Honeybees were rewarded with sucrose solution for choosing AX(a grey target, X, labelled with a distinctive stimulus, A) rather than ABX (a grey target labelled both with A and with another distinctive stimulus, B)–AX+/ABX– training. Tests of independent groups made after such training showed a clear preference not only for AX over ABX, but also for ...

Sensory Preconditioning in Honeybees
Journal of Experimental Biology, 2000ABSTRACT Sensory preconditioning means that reinforcement of stimulus A after unreinforced exposure to a compound AB also leads to responses to stimulus B. Here, we describe and analyze sensory preconditioning in an insect, the honeybee Apis mellifera.

Identification of Africanized honeybees
Journal of Chromatography A, 2005Gas chromatography and pattern recognition methods were used to develop a potential method for differentiating European honeybees from Africanized honeybees. The test data consisted of 237 gas chromatograms of hydrocarbon extracts obtained from the wax glands, cuticle, and exocrine glands of European and Africanized honeybees.

Intermodal blocking in honeybees
The Quarterly Journal of Experimental Psychology B, 2001Previous findings of intramodal but not of intermodal blocking in foraging honeybees prompted a new series of experiments with colours, odours, a proximal visual landmark, and a localized geomagnetic anomaly as stimuli. In Experiments 1-2, the landmark was blocked by both colour and odour.

The mushroom body (MB) in the insect brain is composed of a large number of densely packed neurons called Kenyon cells (KCs) (Drosophila, 2200; honeybee, 170,000). In most insect species, the MB consists of two caplike dorsal structures, the calyces, which contain the dendrites of KCs, and two to four lobes formed by collaterals of branching KC axons ...

Canadian Journal of Ophthalmology, 2005
We report the complications and management of a retained bee sting injury to the cornea. The case highlights the acute and chronic management of an uncommon injury and its pathogenesis.A 67-year-old man was attacked by a swarm of bees and was referred for severe chemosis on the right eye. A retained corneal bee stinger (ovipositor) was seen but removal

Probiotics for Honeybees’ Health
2017Honeybee is certainly one of the most familiar flying insects of terrestrial habitats. Honeybees are critically important in the environment, sustaining biodiversity and providing essential pollination for a wide range of crops and wild plants. Extensive losses of honeybee colonies in recent years are becoming a major cause of concern.

Abstract Humankind has displayed keen interest in bees since the dawn of history. There is no evidence that the opposite was ever true. Cave paintings dating 10 000 years ago already depict bold honey harvesters driving away the stinging bees with smoke (Menzel and Mercer 1987). A few millennia later, when the Almighty led the Israelites

The antennal lobe (AL) of an insect is the functional analog of the olfactory bulb in mammals. The first-level synaptic interaction of large numbers of multiple types of olfactory receptor neurons (OSNs) with AL interneurons serves the function of reliably coding a vast range of odorants and their mixtures and the separation between odor identity and ...

Backward blocking in honeybees
The Quarterly Journal of Experimental Psychology Section B, 2004Three experiments with foraging honeybees were designed to study the effect of experience with A on responding to B after AB+ training. In the first experiment, responding to B was the same whether the AB+ training was preceded or followed by A+ training.
