Comments and References

General comments

The virus was originally called cowpea aphid-borne mosaic virus, like that described by Lovisolo and Conti (1966). The latter was probably an isolate of bean common mosaic virus, but is no longer available for comparative tests, and hence a nomen nudum. This virus is best differentiated from the latter by adding "Moroccan" to its name.
