INSECT ENEMIES OF THE FARMER 263 



EXERCISE. Ask the owner's permission to examine the roots of 

 peach trees for borers. In your notebook write a description of what 

 you find. If specimens of the other insects mentioned in this section 

 can be found, place them in bottles and present them to the teacher for 

 examination by the class. 



NOTE TO THE TEACHER. Bulletins on each of these separate in- 

 sects have been issued by the United States Department of Agriculture 

 and by many of the experiment stations. You may render a great 

 service in preventing the destruction of fruit trees by obtaining one or 

 more of these bulletins and, with its help, collecting twigs that seem to 

 be attacked by scale insects. Specimens forwarded to the entomologist 

 at your state experiment station will generally be identified without 

 charge and detailed information will be furnished for the treatment of 

 the insect found.
