in fall and early winter. The essential basis for treatment 

 lies in the time and place of e.i>j2; deposition. The egg is 

 deposited in the calyx of the fruit and the larva burrows 

 into the fruit. 



The whole secret of destroying the species is to have the 

 poison applied placed so that it will get into this particular 

 ])art of the api)le and be there when the lar\a takes its first 

 meal. Proper ap])lication of arsenical solution will prevent 

 95 to 98 per cent, of the injury. Application should be 

 made ver\' soon after the bloom falls while the fruit is still

open at the calyx end. There are two broods in a season, 

 The larvfe seen in the apples in the winter are the ones from 

 the second brood. They escape from the apples when 

 stored and secrete themselves about the bins and change to 

 pupse, and the moths are ready to issue early in the spring. 

 The insects may be captured as pup?e at the end of the first 

 brood so as to prevent the issuing of the midsummer moths. 

 This may be done by means of bands around the trees 

 under which the larvae will crawl to pupate. These bands 

 may be examined every few days and the i)U])a' crushed.
