DETECTION OF Citrus sudden death-associated virus AND HAPLOTYPES OF Citrus tristeza virus IN Toxoptera citricida AND Aphis spiraecola AND IMPLICATION ON CITRUS SUDDEN DEATH IN BRAZIL
Individuals of Toxoptera citricida (Kirkaldy) and Aphis spiraecola (Patch) collected in 16 commercial citrus orchards of the São Paulo and Minas Gerais States of Brazil were analyzed for virus presence. Orchards of Minas Gerais were selected because citrus trees exhibit symptoms of citrus sudden dea...
