Fig, 1.—a, small apple from which the petals have just fallen. Effective spraying for 
the codling moth may be done in this stage but it is not in as good condition for receiving 
the spray as b; b, small apple in the proper condition to receive the first spray for codling 
moth. The calyx-lobes have begun to close and form somewhat of a cup for holding the 
liquid and the stamens have begun to dry and will allow the liquid to enter the inner part of 
the calyx cup; c, cross section of b, showing the calyx cup, all parts of which must be 
covered with the spray to effectively poison the worms; d, pear in condition to receive the 
spray. Original. Miriam A. Palmer, Delineator. 
some sections of the country, but in most parts of this State, where 
the second brood is several times as large as the first, it will usually 
bring disappointing results. By this method, it is possible to poison 
the 65 percent that enter the calyx, but it gives little or no protection 
against the remaining 35 percent that enter the side of the fruit. 
Fig. 2.—Blossoms from which the petals have fallen and still in good condition to re¬ 
ceive the spray. The calyces of the two larger ones have closed. It is too late to effectively 
apply the calyx spray to them.
