Lessons in Fruit Growing. 



ally in the calyx of the young fruit but sometimes on other 

 parts of the fruit or upon the leaves. The egg hatches in 

 a few clays and the larva proceeds to eat a passage to the 

 core of the young fruit, pushing its castings out behind it 

 and enlarging the channel from time to time. The reddish- 

 brown castings usuall}^ adhere more or less about the en- 

 trance of the opening. The larva (e) feeds on the interior 

 of the fruit during three or four weeks or until it attains 

 full growth, when it 

 leaves the fruit and 

 seeks a secluded place 

 for pupation, which it 

 usually finds under the 

 rough bark or in cracks 

 and crevices about the 

 trunk of the tree. The 

 injured fruit generally 

 falls from the tree be- 

 fore, or soon after the 

 larva leaves it. In

The early and later broods are not sharply defined, but 

 overlap more or less, so that the larvae of the early brood 

 may not all have left the fruits at the time some of the sec- 

 ond brood are hatched. The larvae of the second brood be- 

 come full-grown during autumn or early winter and often 

 do not escape from the fruit until after it is harvested. They 

 may remain in the fruit during a considerable part of the
