INSECT PESTS OF CIGAR-TYPE TOBACCOS 7 
In case cutworms are found to be causing damage in plant. beds, 
control may be effected by applying poisoned-bran bait. The for- 
mula and preparation of this bait are described in detail on page 
34 of this circular. The bait should be scattered around the margins 
of infested beds, in the walkways, and in any open spaces where the 
plants are missing. The bait should not be thrown onto the tender 
plants, as this will cause considerable burning of the foliage. As 
cutworms feed mainly at night it is desirable that the application be 
made late in the afternoon, near sundown, so that the bait may be 
fresh and attractive when the insects become active. About 4 pounds 
(dry weight) should be used to each 100 square yards of plant bed.

THE Tospacco BupDwoRM 
The tobacco budworm is one of the major insect pests of cigar 
tobacco in the southern districts. In this region budworm attacks

are almost exclusively by the tobacco budworm (Heliothis virescens 
(F.)), whereas in certain other sections of the United States and in 
Jamaica the bollworm, or corn earworm (Heliothis armigera (Hbn.) ), 
also attacks tobacco in appreciable numbers. Although the budworm 
feeds on all types of tobacco grown in this region, injury to leaves 
to be used as cigar wrapper is more serious than injury to leaves of 
other types owing to the expense connected with the production of 
wrapper tobacco and the fact that soundness of leaf is of greatest 
Importance in this type. The infestations occurring in the binder and 
filler types, however, are so great as also to necessitate control 
practices. 
DESCRIPTION AND HABITS 
The small, whitish eggs from which the budworms hatch are de- 
posited by a greenish-colored moth (fig. 7). They are laid singly,
