Viruses are extremely small particles which can only be seen with an electron microscope. A virus is present in a diseased plant as huge numbers of tiny particles within the cells of the plant. Viruses which are infectious can cause disease, and reproduce only inside the cells of a living plant.
Many insects transmit plant virus diseases—aphids, leafhoppers, mealy bugs, thrips and beetles. Generally a virus is spread by only one of these groups of insects.
The Western Australian Department of Agriculture is expanding the diagnostic service for the identification of plant viruses.
