The first lots of asparagus received at processing terminals in the Shelby, Michigan area in May of 1959, were heavily contaminated with case-bearer larvae of the family Coleophoridae. Various methods were unsuccessful in an endeavor to dislodge the larvae from the spears. As a result, a detailed investigation was initiated to ascertain the origin, life history, and possible control of this insect.
