The rôle of aphids in the transmission of virus diseases of celery, Apium graveolens Linn., var. dulce, in California has attained considerable economic importance in recent years. The object of this paper is to furnish information as to the identity of the various species involved, the determination of which has been a difficult task. It has been especially complicated by the large number of different species discovered feeding on celery and by the fact that the species appear to be considerably altered, particularly in size, when reared in the greenhouse. Many of the species studied appear to be introduced, while others are undoubtedly indigenous. An abundance of wild umbelliferous plants, growing in all of the celery-producing sections of California, affords a continuous and ample food supply throughout the year. Certain of the aphids studied alternate from these hosts to willow, honeysuckle, and many other cultivated and wild plants. Carrots and celery are extensively grown as winter crops in many parts of California and aphids may be found upon them almost any time of the year.
