Abstract

Resistance to the initiation of feeding by newly hatched larvae of Hylemya brassicae (Bouché) confined on surfaces of rutabaga roots was examined. Differences between varieties could be distinguished by using 10 larvae on a root segment. There were no differences between roots within a variety or between portions of one root. The evidence of resistance in Wilhelmsburger was confirmed. This technique of rearing on a small surface area of the root may be valuable in evaluating lines in the laboratory without destroying their propagation value.
