A chlorotic veinbanding disease of raspberries is shown to be due to a virus transmissible by the aphidAmphorophora rubiKalt. after infection feeding periods of 18 hr. or more.This virus causes leaf symptoms, masked in hot weather, on a wide range of European and North American varieties. Symptoms on the latter are analogous to those of the red raspberry mosaic of American authors.The names veinbanding disease and raspberry veinbanding virus are proposed.
