Slow Bee Paralysis Virus
Slow bee paralysis virus (SBPV) is a virus discovered in England in 1974 that infects honeybees (''Apis mellifera''), bumblebees (''Bombis spp.)'', and silkworms (''Bombyx mori)'' through '' Varroa destructor'' mite infestations. The virus causes paralysis in the front two pairs of legs of adult bees eventually killing its hosts. The virus is in the iflaviridae family of viruses. Infection by iflaviridae viruses is among the leading cause of death of honeybee colonies. As bees and silkworms are of great economic and biological importance, the virus is the subject of ongoing research. Structure The virus has an "... icosahedral capsid formed from sixty copies of three proteins which are common to picornaviruses." These proteins are 46, 27, and 29 kilodaltons. One of these three proteins (VP3) has a C-terminal globular domain which folds to create a single globular protein P domain. The position of this protruding protein is such that it may easily encounter and interact with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honeybee Polen
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the western h ...
