This paper presents a novel version of the bees algorithm. This version is characterized by an extended set of search operators, and a mechanism that protects the most recently generated solutions from competition with more evolved individuals. Compared to the standard implementation of the bees algorithm, the new procedure requires the selection of an additional set of parameters

Honey bees are very much a part of the modern American agricultural picture. It is estimated that there are 2.9 million colonies in the United States today (owned by beekeepers with five or more colonies). Over two million of these colonies are on the road each year to pollinate crops and to produce honey and beeswax.

The honey bee is a model organism for studies on the neural substrates of learning and memory. Associative olfactory learning using sucrose rewards is fast and reliable in foragers and older hive bees. However, researchers have so far failed to show any signiWcant learning in newly emerged bees. It is generally argued that in these bees only part of the brain structures important for learning are fully developed.

Europe harbours several endemic honeybee (Apis mellifera) subspecies. Yet the distribution of these subspecies is nowadays also much influenced by beekeeping activities. Large scale migratory beekeeping and trade in queens, coupled with the promiscuous mating system of honeybees, have exposed native European honeybees to increasing introgressive hybridization with managed non-native subspecies,

There has been a renaissance in recent times in the use of honey, an ancient and traditional wound dressing, for the treatment of wounds, burns, and skin ulcers. In the past decade, there have been many reports of case studies, experiments using animal models, and randomized controlled clinical trials that provide a large body of very convincing evidence for its effectiveness, and biomedical research that explains how honey produces such good results

The widespread existence of unhealed wounds, ulcers, and burns has a great impact on public health and the economy. Many interventions, including new medications and technologies, are being used to help achieve significant wound healing and to eliminate infections.

The antibacterial activity of honey samples provided by apiarists and honey packers was tested against microorganisms usually isolated from skin wounds. The antibacterial activity was tested using the well-agar diffusion assay. The honey samples were tested without dilution, and at 75, 50, 30, and 10% (w/v) dilution

Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony with a genetically diverse worker force. The adaptive significance of polyandry by social insect queens remains an evolutionary puzzle. Using the honeybee (Apis mellifera), we tested the hypothesis that polyandry improves a colony’s resistance to disease.

Multiple mating by social insect queens increases the genetic diversity among colony members, thereby reducing intracolonic relatedness and lowering the potential inclusive ï¬tness gains of altruistic workers. Increased genetic diversity may be adaptive, however, by reducing the prevalence of disease within a nest. Honeybees, whose queens have the highest levels of multiple mating among social insects, were investigated to determine whether genetic variation helps to prevent chronic infections.
