During the 2013 growing season, sugarbeet root aphid (Pemphigus betae Doane) were observed on the crowns and petioles of sugarbeet plants in the Red River Valley.  This unusual behavior, last reported in 1956, is attributed to the entomopathogenic fungi Pandora neoaphidis.  Aphids were collected and barcoded to confirm identity from three morphologically similar, sympatric aphid species.  Alate P. betae were collected from a suction trap network to construct a flight phenology.  This data can be used to develop management plans for this yield-limiting pest.
