tobacco plant is subject to the attacks of several species of insects. 
Throughout the tobacco-growing regions of the United States there is 
probably no one insect which does more damage to the marketed prod- 
uct than the tobacco flea-beetle, or ‘‘ flea bug,” as it is commonly 
known to growers (Hpitrix parvula). The large horn worms or ‘‘ horn- 
blowers,” also insects of wide distribution, tobacco growers must 
always fight. -The bud worm, which may be either the larva of Helio- 
this rhexia or of the cotton boll worm or tomato fruit worm or corn- 
ear worm, as it is called according as it affects different plants (larva 
of Heliothis armiger), attacks and bores into the central leaf roll or 
‘“pud” early in the summer, or later in the season into the seed pods 
or into the terminal flower stalk, and even feeds to a certain extent 
upon the leaves. Several species of cutworms are liable to occasion 
replanting in soil which has not been properly treated, and one or 
two of them rag the leaves late in the season. Certain wireworms 
also are liable to affect the young plant shortly after it is set out. 
Two or more species of plant bugs occasionally damage the leaves by 
inserting their beaks and sucking the juices, causing a drying and 
shriveling of the leaf in inuch the same way as the harlequin cabbage 
bug injures the leaves of cabbage. One of these plant bugs, a small 
species, insignificant in appearance, has recently proved to be a seri- 
ous enemy to tobacco culture in Florida. Another new insect, and 
one which may prove to be a very important factor in tobacco cul- 
ture, is the so-called tobacco leaf-miner, or ‘‘ split worm,” an insect 
which although first found in North Carolina only two years ago has 
since made its appearance in Florida, South Carolina, and southern 
Virginia. These comprise the principal species damaging growing 
tobacco at the present time. There is always a chance, however, that 
new insect enemies may make their appearance just as two of those 
above mentioned have done in very recent times, and it is safe to say 
that many of the species which affect solanaceous plants, and especially 
the tomato, are liable to transfer their attentions to the tobacco crop 
under favorable conditions. 
After the tobacco has reached the factory, an insect enemy of impor- 
tance, and which is always to be feared, is the cigarette beetle (Lasi- 
oderma serricorne), a species which riddles the tobacco leaf, which 
bores into or out of manufactured cigarettes and cigars, and which, 
when once introduced into a not over cleanly factory, is very difficult 
to eradicate. Two or three other little beetles have been found in 
dried tobacco, namely, the drug-store beetle (Sitodrepa panicea) and 
the rice weevil (Calandra oryza), but they are not as important as 
the cigarette beetle. 
It is proposed to give in this bulletin a short account of these 
insects and other species of less importance, with some indication of 
the proper remedies under each, and a concluding paragraph on 
remedial work as a whole,
