The Bulletin. 



stalks, as there is no corn available at that season of the year. These 

 larvse, perhaps, become full-grown in three or four weeks, when they 

 pupate, the adults emerging in the fall and pass the winter hidden 

 in sheltered out-of-the-way places beneath sticks and stones, under 

 the bark of trees, etc. 



Control. 



Preventives. — From what has been stated above of the life-history 

 of this pest, it would seem natural that this insect would be worse in 

 tobacco which had followed corn or coarse-growing grasses. In case 

 this insect ever becomes serious enough to be a real pest of tobacco, 

 it would seem to be necessary to see that tobacco did not follow corn 

 or any coarse-growing grass. 



Remedies. — Paris green or arsenate of lead as used against Horn 

 Worms, (page 30) and Flea Bugs (page 35) would be entirely ef- 

 fective against this pest, as the adult beetle is a chewing insect. 



INSECT ENEMIES OF STORED TOBACCO. 



Having considered the insect enemies of growing tobacco, we pass 

 to those insects which injure the dry tobacco leaves in tobacco ware- 

 houses and the manufactured products in stores, etc. So far only 

 two insects have been recorded as injuring stored tobacco in North 

 Carolina. The first and most abundant of these is known as the 

 Cigarette Beetle. The other, which is of much less importance as an. 

 insect enemy of stored tobacco, is known as the Drug Store Beetle.

Cigarette Beetle. 1 

 (Order Coleoptera.) 



This insect is so small that it usually escapes all notice until 

 it has done a large amount of damage, when its fine powder-like 

 castings usually betray its presence. 



The adult beetle (Fig. 54 c and d) is about i/ 8 of an inch long, 

 uniform brown in color, with its body densely covered with fine hair.
