Learning, memory, and social behavior are innate properties of the honeybee that are essential for the survival of each individual as well as for the survival of the hive. The small, accessible brain of the honeybee and the availability of the complete sequence of its genome make this social insect an ideal model for studying the connection between learning, memory, and social behavior.
Honeybees produce silken cocoons containing four related fibrous proteins. High levels of each of the honeybee silk proteins can be produced recombinantly by fermentation in Escherichia coli. In this study we have used electrospinning to fabricate a single recombinant honeybee silk protein, AmelF3, into nanofibers of around 200 nm diameter. Infrared spectroscopy found that the molecular structu...
The greater wax moth, Galleria mellonella Linnaeus, is a ubiquitous pest of the honeybee, Apis mellifera Linnaeus, and Apis cerana Fabricius. The greater wax moth larvae burrow into the edge of unsealed cells with pollen, bee brood, and honey through to the midrib of honeybee comb. Burrowing larvae leave behind masses of webs which causes galleriasis and later absconding of colonies. The damage...
Intrusion Detection System has been studied for more than ten years. Though Artificial Intelligence (AI) techniques have been integrated to improve IDS but the success is still far from satisfaction. Thus, we believe a new strategy to improve IDS is badly needed. One of the solutions is by imitating the honeybee colony that can successfully protect their colony. In fact, the honeybee colony sys...
Vital pollinators whose role in ecosystems can hardly be overestimated, honeybees suffer from numerous illnesses, among which varroatosis and nosemosis seem most dangerous. Unfortunately, there is no cure that could resolve these grave honeybee health problems. Therefore, a great number of various kinds of diet supplements to help combat these illnesses are recommended for honeybee feeding. The...
The honeybee dance "language" is one of the most popular examples of information transfer in the animal world. Today, more than 60 years after its discovery it still remains unknown how follower bees decode the information contained in the dance. In order to build a robotic honeybee that allows a deeper investigation of the communication process we have recorded hundreds of videos of waggle dan...
The long-term decline of managed honeybee hives in the world has drawn significant attention to the scientific community and bee-keeping industry. A high pathogen load is believed to play a crucial role in this phenomenon, with the bee viruses being key players. Most of the currently characterized honeybee viruses (around twenty) are positive stranded RNA viruses. Techniques based on RNA signat...
honeybee is a pollinator that has prominent role in agriculture products and nourishment for human. so, the most number of studies like genetic improvement were done on honeybee. recent advances in knowledge of molecular genetics of bee emphasize the potential for using genetic markers to select favored traits. this research was done to determine polymorphism of loci of first foraging age (aff)...
b a ckground: diabetes is an important disease. this disease is a metabolic disorder characterized by hyperglycemia resulting from perturbation in insulin secretion, insulin action or both. honey bee venom contains a wide range of polypeptide agents. the principle components of bee venom are mellitin and phospholipase a2. these components increase insulin secretion from the β-cells of pancreas....
