Abstract:

Frequent and regular thinning of check trees, in connection with Codling Moth ( Carpocapsa pomonella) control tests, has the advantage of preventing infestation of adjoining test trees, and in addition gives a fairly accurate record of worm activity throughout the season. Evidence of continuous worm work in moderately to heavily infested districts in the Northwest is presented. Results with the omission of the calyx spray suggest the possibility that this spray may not be as important under Northwest conditions as quite generally supposed.
