Ultrastructure of viruliferous Javesella pellucida transmitting Festuca leaf streak virus (genus Cytorhabdovirus)

The ultrastructure of cells in the head and thorax from viruliferous Javesella pellucida transmitting Festuca leaf streak virus was studied. Aggregates of nonenveloped nucleocapsid particles were observed at the periphery of viroplasms located in cytoplasm of salivary gland cells, fat cells, and nerve cell bodies. Aggregates of nucleocapsid particles, not associated with viroplasms, were seen within a distance of about 1 m from the basal lamina of salivary glands. Enveloped virions, singly or aggregated, were observed in nerve cell axons and/or dendrites.
