Whiteflies other than B.
tabaci were first recognized as virus vectors in the Sixties and include until to date the species Trialeurodes vaporariorum, T.
abutilonea and possibly, Parabemisia myricae.
The viruses transmitted, whose type-member may be considered beet pseudo- yellows virus, have been reported from the USA, Europe, Japan and Australia but not so far from Africa, South America or continental Asia.
They mostly infect plants in the families Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceac and Solanacea.se, causing symptoms such as chlorotic spots, yellowing or chlorosis, and thickening, brittleness and downward curling of leaves.
The clostero- like virus particles, 900-1000 nm long and 12 nm wide, with an ssRNA genome, have not been fully characterized at the molecular level but studies on some of the viruses are in progress.
Experimentally, transmission has been obtained by grafting but not by sap or aphid inoculation, by contact or through seed.
The whitefly vectors can transmit with acquisition and inoculation feedings of at least 5 min but the transmission rate increases as both feeding periods are increased.
There is no clear evidence for the presence of a latent period, although infectivity can be retained for up to 6 days.
Some epidemiological aspects of these viruses are discussed with particular emphasis on those that have been detected in Italy.
