Codling moth eggs occurring on canning pears or early apples often hatch after the fruit is picked and sorted. The larvae from these eggs cause considerable injury to the fruit while it is ripening. It is not practicable to kill the eggs by means of cold storage, since it is usually desirable that the fruit ripen as rapidly as possible. Washing the fruit for removal of spray residue does not harm the eggs, but a treatment with dilute oil emulsion in a machine used for residue removal kills the eggs without retarding the ripening of the fruit or affecting its quality.
