Studies of the life history of the codling moth, Carpocapsa pomonella, have been made, partially or fairly complete, at Marietta in southern Ohio, at Wooster in the north central section and at Gypsum in the northwestern section. Records of the dates when the sprays are commonly applied have also been kept through a series of years. The stages of development of the moth at the dates of spraying are shown by the life history chart. The tentative conclusion is reached that when the season is late the summer spray should be earlier than usual instead of later and that a later second summer spray is desirable in such a year.
