This paper reviews the results of a three year cooperative effort against the codling moth, Carpocapsa pomonella, in a heavily infested district near Glassboro, New Jersey.This cooperation existed between a group of more than twelve growers,whose properties involved a total of over 1400 acres of bearing apple,and the New Jersey Agricultural Experiment Station.In 1925,which is the year previous to the inception of this effort,the average percentage of fruit free from codling moth at picking time was 47.4.In 1926 the average clean fruit at picking time in a crop of 280,200 bushels was 68.8%.In 1927 the average clean fruit at picking time in a crop of 378,554 bushels was 80.8%.In 1928 the average clean fruit in a crop of 309,499 bushels was 81.1%.Of course there were individuals,and large producers too,that reached more than 95% clean fruit but there were others that were not as successful and the average consequently stood at the point mentioned.The small increase in average clean fruit at picking time in 1928 may be attributed mainly to the fear of arsenical residue.
