Populations of important pollinators, such as bumble bees and honey bees, are declining at alarming rates worldwide. Parasites are likely contributing to this phenomenon. A distinct resident community of bacteria has recently been identified in bumble bees and honey bees that is not shared with related solitary bee species. We now show that the presence of these microbiota protects bee hosts ag...

The response of male and female Small Hive Beetle (SHB), Aethina tumida, to air-borne volatiles from adult worker bees, (Apis mellifera), pollen, unripe honey, beeswax, wax by-products (“slumgum”), and bee brood, was investigated in olfactometric and flight-tunnel choice bioassays. In both bioassay systems, males and females responded strongly to the volatiles from worker bees, freshly collecte...

Social insects are able to mount both group-level and individual defences against pathogens. Here we focus on individual defences, by presenting a genome-wide analysis of immunity in a social insect, the honey bee Apis mellifera. We present honey bee models for each of four signalling pathways associated with immunity, identifying plausible orthologues for nearly all predicted pathway members. ...

Until now, the properties of honey have been defined based exclusively on the content of plant components in the nectar of given plant. We showed that apalbumin1, the major royal jelly (RJ) protein, is an authentic and regular component of honey. Apalbumin1 and other RJ proteins and peptides are responsible for the immunostimulatory properties and antibiotic activity of honey. For the quantific...

A successful honey bee forager tells her nestmates the location of good nectar and pollen with the waggle dance, a symbolic language that communicates a distance and direction. Because bees are adept at scouting out profitable forage and are very sensitive to energetic reward, we can use the distance that bees communicate via waggle dances as a proxy for forage availability, where the further t...

Honey bees play a vital role in the pollination of crops, fruits, and wild plants [1]. However, pathogens and parasites pose major threats to their fitness and survival due to the large number of declines reported recently in North America and several European countries [2]. Aside from the innate immunity of honey bees, indirect fitness benefits resulting from altered behavior may provide resis...

In this paper, we show the functional similarities between Meta-heuristics and the aspects of the science of life (biology): (a) Meta-heuristics based on gene transfer: Genetic algorithms (natural evolution of genes in an organic population), Transgenic Algorithm (transfers of genetic material to another cell that is not descending); (b) Meta-heuristics based on interactions among individual in...

Honey-bees have long served as a model organism for investigating insect navigation and collective behavior: they exhibit division of labor and are an example of insect societies where direct communication between workers enable cooperation in the task of collecting nectar and pollen for the colony. However, honey-bees seem to learn about their environment progressively before becoming foragers...

Bees are essential pollinators of many plants in natural ecosystems and agricultural crops alike. In recent years the decline and disappearance of bee species in the wild and the collapse of honey bee colonies have concerned ecologists and apiculturalists, who search for causes and solutions to this problem. Whilst biological factors such as viral diseases, mite and parasite infections are undo...

A restrained honey bee can be trained to extend its proboscis in response to the pairing of an odor with a sucrose reward, a form of olfactory associative learning referred to as the proboscis extension response (PER). Although the ability of flying honey bees to respond to visual cues is well-established, associative visual learning in restrained honey bees has been challenging to demonstrate....
