picture info	Closteroviridae ''Closteroviridae'' is a family of viruses. Plants serve as natural hosts. There are four genera and 59 species in this family, seven of which are unassigned to a genus. Diseases associated with this family include: yellowing and necrosis, particularly affecting the phloem. Taxonomy Genome type and transmission vector are two of the most important traits used for classification. Ampeloviruses and Closteroviruses have monopartite genomes and are transmitted by pseudococcid mealybugs (and soft scale insects) and aphids respectively. While Criniviruses are bipartite and transmitted by whiteflies Whiteflies are Hemipterans that typically feed on the undersides of plant leaves. They comprise the family Aleyrodidae, the only family in the superfamily Aleyrodoidea. More than 1550 species have been described. Description and taxonomy The ....
