Thf. Codlin(;-Moth. 



lo-; 



We have noted above that Mr. Card found niOot of the eggs of the 

 codhng-moth laid upon the leaves instead of on the fruit in Nebraska. 

 In confinement, he fou!id that the young worms sometimes fed for 

 twenry-four hours on the leaves where they hatched, and ate out quite 

 large pieces, usually eating away one skin of the leaf and the inner 

 tissue, leaving the other skin intact. Whether they fed upon the 

 leaves to any extent in the orchard was not determined. 



Where it spends the first feiv days of its life. — Apparently the newly- 

 hatched apple-worm spends but a few hours of its life on the skin of 

 the fruit. Whenever it enters at any other point than at the calyx, it 

 usually soon begins to tunnel toward the core. However, 75 per cent, 

 or more of the young worms enter the fruit at the blossom-end, and 

 our observations indi- 

 cate that they spend 

 several days feeding 

 around in the calyx 

 cavity. When the 

 worms hatch, the blos- 

 soms have been off for 

 two weeks or more, and 

 the calyx lobes have 

 drawn tightly together 

 (compare figure 146 

 and a and b in figure 

 131) forming a covered 

 cavity in the blossom- 

 end of the apple; this 



does not happen in the '33-—'^ it>oimy apple, mowini^ the Jamiltar mass of 



broion partictes t/irown out at the blossom-end by 

 case of the pear, as the tJie young worm, 



central picture in figure 



146 shows. This is a very important phase in the habits of the apple- 

 worm, as we shall see when we come to discuss " remedies." 



All are familiar with the first indications that the apple-worm has 

 begun work; the masses of little brown particles which it thrusts out 

 of the calyx are quite conspicuous, as shown in figure 133. These 

 first few days of the apple-worm's life, which are usually spent in feed- 

 ing in the blossom-end of the fruit, have proved to be the most vulner-
