Examinations of Codling Moth (Carpocapsa pomonella) larvae hibernating on trunks of trees showed 30% of the larvae at or just below the ground line. On the ground between the trees eight times as many larvae were found in artificial situations as in natural cover. Pieces of bark were the only type of natural cover in which larvae on the ground were found. In preliminary tests with emulsions of fish oil soap and of orthodichlorobenzene no penetration of the hibernaculae was effected.
