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

Honeybee pollinators use visual and floral scent cues to find apple (Malus domestica) flowers.
Journal of Agricultural and Food Chemistry, 2019Apple flowers of most varieties require pollinator-mediated cross-pollination. However, little is known about the cues used by pollinators to find the flowers.

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 ...

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. In the second experiment, responding to B after AB+ training was less in animals that also had A+

To report a rare case of corneal honeybee sting.The corneal honeybee stinger was removed under slit-lamp guidance using a 27-gauge needle.Corneal edema resolved by 90% the next day after removal of the honeybee stinger without using topical steroids.The patient's condition improved significantly after removal of the corneal honeybee stinger, and ...

Swarm Orientation in Honeybees
Science, 1963A swarm of honeybees will move up to 75 m (250 feet) without its queen but only for 3 to 8 minutes. The swarm is aware of the presence of its queen, but the queen does not lead the swarm from one location to another. Bees return to a queen which cannot follow the swarm in flight and in fact are capable of finding a queen "lost along the way." The ...
