Aphid Vectors of European Raspberry Viruses

Abstract

The failure in vigour and productivity of cultivated raspberries during the last decade in England, and more especially in the concentrated raspberry-growing districts of Scotland, has been due mainly to the spread and cumulative effect of a number of virus diseases. This has been amply demonstrated by the work of Harris^1,2 and our own unpublished work. A precise determination of the viruses concerned and of their interrelations and the development of remedial measures have, however, been severely handicapped by the absence hitherto of information on the natural vectors of the viruses concerned.
