Many apricot orchards in the Santa Clara Valley have been severely attacked by the codling moth for a number of years. The losses in wormy fruit at harvest have frequently been as high as 30% to 50% of the crop. The attempts of some growers at control were usually unsatisfactory and at their request the Division of Entomology and Parasitology at Berkeley started a field investigation of the problem in the spring of 1948.
