1. Aphis rubiPhila Patch was the only insect carrier of raspberry leaf curl among several insects used. 2. The aphids must feed upon a diseased plant before becoming a carrier. 3. The infective agent is not carried over winter within the egg from the fall generation to the spring forms. 4. The infective agent is not inherited by the offspring in viviparous reproduction. 5. Leaf curl was transmitted from black to red raspberries but not from red to black varieties. The first plant disease of the mosaic type shown to be transmitted by . insects was "curly-top" of sugar beets. Shaw (6), in 1910, proved experimentally that Eultetix tenella Baker was the only common carrier.
