Some Possibilities in Codling Moth Control

There is a general demand for other methods of control of the codling moth, Carpocapsa pomonella , to supplement that of spraying. Under some conditions spraying alone is not proving satisfactory. The use of bands, orchard sanitation, and picking wormy fruit should be made more use of. Ovicides show possibilities as a means of reducing the number of stings. Oils have proven the most efficient ovicides. It is possible to trap large numbers of adult codling moth. A fermenting sweetened apple juice is proving to be a valuable attractant. The traps can be used as a means of determining the insect development in an orchard for the establishment of spray dates.
