Rice root aphids (RRAs) feed on a range of monocotyledonous and dicotyledonous plants. In choice experiments with two potted plants, RRAs invariably selected and multiplied faster on monocotyledonous rye than on dicotyledonous cannabis, celery, coriander, lettuce, pepper, squash, tomato, or marigold.
