Epidemiology of Strawberry pallidosis-associated virus and Occurrence of Pallidosis Disease in North America.

Strawberry pallidosis-associated virus (SPaV) was found closely associated with pallidosis disease. The modes of transmission of the virus were studied, including pollen, seed (achene), and whitefly transmission. Three whitefly species were tested for their ability to transmit SPaV, but only the greenhouse whitefly, Trialeurodes vaporariorum, was identified as a vector of the virus.
