HOW TO USE THIS BULLETIN 



TpAMILIARITY with the arrangement of this bulletin will aid in its use. 

 ■*• The more common flowering and ornamental plants are arranged 

 alphabetically in the section Insects Attacking Specific Plants (pp. 18 to 

 94), as indicated in the table of contents. Under each plant the pests 

 most likely to attack it are mentioned, and either a discussion or a refer- 

 ence to a discussion elsewhere in this publication follows. 



If the name of the insect or group of insects is known, consult the 

 index at the end of the publication for the page reference. If the insect 

 is not known, look under the name of the plant that is infested. From 

 the descriptions of the insects and the nature of the injury which they 

 cause, attempt to identify the pest responsible for the damage. The 

 treatment and preventive measures suggested for control are given at the 

 end of the discussion on each pest. 



If the plant is not listed, or the discussion of the pest causing injury 

 cannot be located, consult the section on insecticides (pp. 94 to 106) for 

 general control measures. The materials used to combat insects, and 

 methods for their preparation, are also discussed in this section. 



Since this publication was prepared, DDT has become an outstanding 

 insecticide. Therefore, a brief discussion of the preparation and possible 

 uses of DDT for the control of certain insects has been included as an 

 appendix. 



This publication supersedes Farmers' Bulletin 1495, Insect Enemies o 

 the Flower Garden.
