What are the common orchid viruses and their transmission routes?
I. Common orchid viruses 1. Cymbidium mosaic virus, abbreviated CyMV (1) Symptoms: Orchid plants infected with Cymbidium mosaic virus frequently tend to develop necrosis symptoms, such as black necrotic spots, necrotic stripes, etc. In addition to necrosis on the leaves and stems, infected plants also develop necrosis on the flowers, which is a symptom unique to Cymbidium mosaic virus. Orchid varieties that are easily susceptible include Cymbidium sinense, Cattleya, Oncidium, Cymbidium hookerianum, Vanda, and Phalaenopsis. Necrotic spots sometimes appear only on the lower surface of the leaves and not on the upper surface; this phenomenon occurs in Oncidium, Dendrobium, Vanda, and Phalaenopsis, and is therefore often mistaken by growers for a fungal infection. Some Cymbidium plants infected with Cymbidium mosaic virus, such as Cymbidium hookerianum, Cymbidium sinense, Oncidium, and Phalaenopsis, also develop yellow-green mottled mosaic or yellow chlorotic streak symptoms. In addition, some orchid species show no recognizable symptoms after infection.
