The polyphagous aphid Myzus ornatus was susceptible to infection with strawberry crinkle virus (SCV) when inoculated with extracts prepared from infected Chaetosiphon jacobi, a natural vector species. However, only occasionally during six consecutive serial passages of SCV did feeding by injected M. ornatus result in development of the strawberry crinkle symptoms in Fragaria vesca test plants. Electron microscopy indicated the presence of virus particles in similar tissues, including salivary glands, in both M. ornatus and C. jacobi.
