INTRODUCTION 
The production of cigar tobacco in the southeastern part of the 
United States is centered around Gadsden and Madison Counties, 
Fla., and Decatur County, Ga. Three types—wrapper leaf, binder 
leaf, and filler leaf—are raised in these districts. The wr apper type 
is grown under artificial shades (fig. 1) while the binder and filler 
types are produced in open fields (fig. 2). 
The hot, humid climate and mild winters of this region are favor- 
able to insect abundance, and these pests are one of the most. trouble- 
some factors of tobacco culture. While insects attack all types of to- 
bacco, the wrapper type suffers the greatest reduction in value from 
such 1 injury. Even a few small punctures in leaves of this type cause 
a considerable depreciation, because cigar wrappers can be cut only 
from sound leaf areas. This type can be raised successfully only 
with the careful use of insect-preventive methods and by the timely 
application of direct-control remedies. Effective control measures 
must also be used on the sun-grown types of cigar tobacco or severe 
damage will result. 
This circular is an attempt to bring together in available form all 
the more pertinent facts concerning the habits and control of the
