Abstract:

A sampling technique to estimate percentage of infestation of wheat by Cephus Pygmaeus (L.) was developed in 1982 and implemented in 1983. The sampling technique consisted of examinations of four sets of 50 contiguous stems; two such sets 15 m in from the middle third of both long field edges were examined for a total of 200 stems per field. Infestations in Delaware were low, averaging ca. 2% both years. Infestations were heaviest along field edges and decreased approaching field centers.
