摘要
Citrus tristeza virus in Australian citrus is a complex of isolates that differ in biological properties and rates of aphid transmission. Biological characterization of isolates on citrus indicators produced a range of symptoms varying in type and severity depending on the field host and geographical location. Single aphid transmissions with the vector Toxoptera citricida separated some of these subisolates based on biological indexing on three citrus indicators and the numbers of inclusion bodies produced. Inclusion numbers produced in Citrus aurantiifolia were positively related to isolate and subisolate severity in that host.
