The killing effect of vegetable, animal, and mineral oils on the eggs of the codling moth and the oriental fruit moth

The ovicidal properties of various vegetable, animal, and mineral oils were tested in an effort to develop a supplementary method of control for the codling moth and the oriental fruit moth. The reasons for undertaking this problem are twofold: first, the codling moth has become exceedingly difficult to hold in check; and, second, in the case of the oriental fruit moth there is no satisfactory method of control. The studies could be carried on with both insects because they are very closely related and also, because the oriental fruit moth is a pest of apples as well as peaches.
