Iflavirus aladeformis
Assigned virus:
• deformed wing virus (DWV)
The deformed wing virus is wide-spread and affects honey bee colonies. It may either results in wing deformity or not cause apparent symptoms. In the first case, the wings are often tiny or undeveloped. Other abnormalities may also become visible. Infected bees only live for about 2 days and are normally expelled from the hive. The virus disease can be transmitted by Varroa destructor.
The particles of DWV are icosahedral and about 30 nm wide. The RNA genome has a length of about 10,000 nt and encodes a large polyprotein. Several, closely related variants of DWV have been described. This includes a virus that has been named "Varroa destructor virus 1". This virus is also called DWV Type B and has been originally isolated from the parasitic honey bee mite Varroa destructor. Type B typically causes few symptoms.

Iflavirus aladeformis belongs to the family Iflaviridae (order Picornavirales). This family includes insect viruses similar to the "infectious flacherie virus" which infects silkworms. The viruses contain single-stranded positive-sense RNA.
