crickets (page 64), and Katydids (page 61) eat larger or smaller 

 holes in the leaf. The Spotted Melon Beetle or Corn Bud Worm 

 (page 65) often eats small, irregular holes in the leaf, and various 

 worms, such as Cutworms (page 41) and Cabbage Loopers (page 62), 

 eat larger or smaller portions of the leaf. So far, no sucking insects 

 which destroy the leaf by puncturing it and sucking out its juices 

 have been discovered in North Carolina, although they have been 

 discovered in other tobacco-growing sections. A chewing insect, the 

 Split Worm (page 53), which works between the two sides of the 

 leaf and leaves large, irregular white blotches, is often destructive. 



The Stalk. — The stalks of tobacco are often injured by Bud Worms 

 (page 36), which mine the stalk near the base of the leaves, causing 

 them to wilt. Pith Worms (page 48) dig their tunnels in the center 

 of the stalk near the ground. The Spined Soldier-bug (page 58) 

 sometimes causes the entire plant to wilt by inserting its beak into 

 the stem and sucking out the juices of the plant. Cutworms (page 

 41) of various kinds cut off the young plants at the surface of the 

 ground, and later Cutworms (page 41) often climb the larger plants 

 and do a slight amount of damage by eating away portions of the 

 stalk. Grasshoppers (page 59) and Katydids (page 61) are often 

 offenders in this respect also. 



The Roots. — Wireworms (page 51) are often very injurious to 

 the roots of tobacco, tunneling through the roots in various direc- 

 tions. They often completely cut off the roots of the young plant 

 by making tunnels in various directions through the larger roots, 

 thereby causing the plant to die. 



The Seed Pods. — Seed pods are drilled into by both kinds of Bud 

 Worms (page 36), thus preventing the seeds from ripening. Climb- 

 ing Cutworms (page 41) often cut through the slender stems which 

 support the seed pods, thus causing them to wither and die. 



CONTROL OF TOBACCO INSECTS. 



Under this heading we will discuss such remedies as are thought 

 to be practicable for the tobacco farmer to employ. During the past 

 year the writer carried on a series of experiments in tobacco fields 

 to determine practical methods of controlling the principal tobacco 

 insects, and while these experiments were greatly interfered with by 

 successive rains, enough evidence was gathered to prove conclusively 

 that certain insects can be controlled at a profit by following the 

 recommendations given herewith. Under the special headings, 

 remedies are to be found, with the discussion of each insect. The 

 remedies discussed under the heading, "Principal Insect Enemies of 

 Tobacco," may be safely and economically followed every year.
