Abstract
The relative occurrence in Spain of two whitefly transmitted closteroviruse s causing similar yellowing diseases in melon and cucumber greenhouse crops was studied. Based on a RT- PCR assay, a 1994-1997 survey of Spanish green houses showed that the recently described Bemisia tabaci-transmitted cucurb it yellow stunting disorder virus (CYSDV) has displaced the Trialeurodes va porariorum-transmitted beet pseudo-yellows virus (BPYV), a virus that was p resent in the area since the late 1970s. The CYSDV transmission rates by ea ch of the two biotypes of B. tabaci present in Spain were compared. The res ults showed that the ubiquitous 'B' biotype and the resident 'Q' biotype (f ound in Spain and Portugal) were able to transmit CYSDV with similar effici ency.
