The percentage of curly leaf (curly top or blight) which develops in beet fields after the spring dispersal of the beet leafhopper (Eutettix tenella Baker) from the plains and foothills depends upon the number of leafhoppers on each beet. Seventeen per cent of the spring brood adults collected on the foothills of Little Panoche Valley in the San Joaquin Valley transmitted curly leaf to sugar beets. One per cent of the winter host plants, namely Red Stem Filaree (Erodium cicutarium) harbored curly leaf under natural conditions on the foothills of Little Panoche Valley.
