Aparavirus

Aparavirus is a genus of viruses in the order Picornavirales, in the family Dicistroviridae. Invertebrates, honeybee, and bumblebees serve as natural hosts. There are six species in this genus. Diseases associated with this genus include: ABPV: paralysis. This virus plays a role in sudden collapse of honey bee colonies infested with the parasitic mite varroa destructor.[1][2]

Life cycle

Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Invertebrates, honeybee, and bumblebees serve as the natural host. Transmission routes are contamination and saliva.[1]
