Ascosphaera Apis
''Ascosphaera apis'' is a species of fungus belonging to the family Ascosphaeraceae. It was one of the first entomopathogen genomes to be sequenced. It has a cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext .... It causes the chalkbrood diseases in bees, which rarely kills infected colonies but can weaken them and lead to reduced honey yields and susceptibility to other pests and diseases.

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

List Of Diseases Of The Honey Bee
Diseases of the honey bee or abnormal hive conditions include: Pests and parasites ''Varroa'' mites ''Varroa destructor'' and ''V. jacobsoni'' are parasitic mites that feed on the fat bodies of adult, pupal and larval bees. When the hive is very heavily infested, ''Varroa'' mites can be seen with the naked eye as a small red or brown spot on the bee's thorax. ''Varroa'' mites are carriers for many viruses that are damaging to bees. For example, bees infected during their development will often have visibly deformed wings. ''Varroa'' mites have led to the virtual elimination of feral bee colonies in many areas, and are a major problem for kept bees in apiaries. Some feral populations are now recovering—it appears they have been naturally selected for ''Varroa'' resistance. ''Varroa'' mites were first discovered in Southeast Asia in about 1904, but are now present on all continents except Australia. They were discovered in the United States in 1987, in New Zealand in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
