The fii-st spraying for the codling mothshould l)e given just after the blossoms liave fallen and l)eforothe sepals of the calyx close, the object being to place the poisonin the calyx cavity so that the little larva will be poisoned when itenters and feeds in the calyx a few weeks later. In general this. Fig. ;-Fu11 grown larva of the codling moth—enlarged about tlireetimes. (After Slingerland.) spraying should be given within a week or ten daj-s after two-thirds of the petals have dropped, but the time will depend uponthe variety and the season. In the West great emphasis has recently been placed uponusing a coarse spray with a high pressure, 100 to 250 pounds,w^hich will drive the spray through the bases of the stamensinto the lower calyx cavity, and though excellent result areundoubtedly secured in this way, experiments in the Eastindicate that a mist spray is equally effective if thoroughlyapplied, whether the lower calyx cavity is reached or is no question, however, of the importance of maintaining 630 INSECT PESTS OF FARM, GARDEN AND ORCHARD a good pressure, of at least 100 pounds, so that the spray maybeforced through the fohage; for the 1 )lossoms point in all directions^and the spray must be forced through the tree to reach those point-ing inward on the oppos
