Summary 1. Collections of Cydia pomonella were made in France in 1928 and 1929–30. 2. The numbers of moths and parasites that emerged from the collections are given. 3. The biology and host-lists of the parasites are dealt with, and information on the larval anatomy is given. 4. Low percentages of parasitism of the larvae were found, and it is concluded that predacious birds, and the removal of larvae with the crop, must be important factors in the control of the Codling Moth in France.
