Factors Determining Transmission of Persistent Viruses by Bemisia tabaci and Emergence of New Virus-Vector Relationships

• Samuel Wilson

Many plant viruses depend upon insect vectors for his or her transmission and dissemination. The whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) is without doubt one of the most essential virus vectors, transmitting greater than 4 hundred virus species, the bulk belonging to begomoviruses (Geminiviridae), with their ssDNA genomes. Begomoviruses are transmitted by B. tabaci in a persistent, circulative method, throughout…
