| Abstract:
Spread of sharka from Japanese plum trees to apricot trees and between apricot trees was extremely rapid in our orchards, but the spread to peach trees was much slower. Canino variety, the most important apricot cv. in Valencia, has been specially susceptible to sharka virus. Aphis gossypii was the most abundant species in the orchards studied and it was also the most abundant species landing on apricot leaves and shoots. Although Aphis spiraecola was not an abundant aphid on leaves, it must be taken into account because of its presence on shoots. A. gossypii has never been demonstrated to be a vector of sharka virus. Our transmission assays have not given positive results either. | |
