ORCHARD LIFE. l8l 



the injury to them. Where does the larva enter the 

 fruit? Where is the injury chiefly done? Where 

 does the larva emerge from the fruit? 



2. In what place is it probable that the eggs of 

 this insect are laid, judging by the observations that 

 you have made on the habits of the larvas ? 



3. Collect a large number of the larvae by remov- 

 ing them from wormy apples, and place them in a 

 tightly closed jelly-glass or other small cage. Put 

 some pieces of apple in the cage to serve as food. 

 Put also some small pieces of bark in the cage so 

 that the larvae may hide under them. 



4. Describe the larva, and preserve some speci- 

 mens in alcohol. 



5. Observe the larvse daily until they make their 

 cocoons, and then describe the cocoons. Note date 

 when the cocoons are made, so as to determine the 

 length of time spent by the insect in its cocoon. 



6. Try to find similar cocoons under loose bark 

 on apple trees. 



7. Empty cocoons of this insect are often found 

 under loose bark that has been pierced by a wood- 

 pecker in order to feed on the insects. Preserve 

 specimens of such pieces of bark and cocoons. 



8. Scrape the loose bark from the trunk of an 

 apple tree, and then take a piece of wrapping paper 

 long enough to reach around the trunk and fold it so 

 as to make a band about three inches wide, and fasten 

 this band about the trunk. The band can be fastened 

 in place with a tack or with a cord. Look beneath 

 this band once a week, and collect the larvae and 

 pupae that you find there, keeping a record of the 

 number found each week.
