Summary

Not available – first paragraph follows:

A European weed, London rocket (Sisymbrium irio), which is distributed from coastal and interior southern California to Modoc County in northern California, has been found to harbor Spiroplasma citri. We have succeeded in demonstrating transmission to London rocket by leafhoppers, Scaphytopius nitridus and Circulifer tenellus, and from these field plants to periwinkle (Vinca rosea) by C. tenellus.
