Abstract
Whiteflies are one of the important vectors of plant viruses that feeding of plant as a general pest, and also have a very high potential for transmitting plant viruses. Whiteflies transmit about 114 species of plant viruses belonging to 5 genera in three families. Among them, the Begomovirus genus has the highest percentage of transmission by whiteflies, which are transmitted exclusively by the Bemisia tabasi and in a persistent manner. The Crinivirus and Colesterovirus viruses belonging to the family Colesteroviridae are transmitted semi-persistent by various species of Trialeuroides and Bemisia, and members of the genus Ipomoviruses (Potyviridae family) are transmitted non-persistent and semi-persistent by various species of whiteflies. The virus species and pathogenicity, the species and biotype, sex and age of the vector, the presence of symbionts in the hemolymph and the resistance of the vector to various chemical toxins are the most important factors to determining the efficiency of plant virus transmission by whiteflies.
