hibernating weevils have all issued. Each planter will therefore 
receive practically the full benefit of all efforts made to control the 
pest whether his neighbors do so or not; but practically the same fight 
will have to be made each season, whereas if all cooperated, the pest 
would gradually, but certainly, be so reduced that the expense of 
making war on it would be lowered to a minimum. 
DISTINCTION BETWEEN BOLL WEEVILS AND ACORN WEEVILS 
AND SHARPSHOOTERS. 
The opinion is often expressed that the acorn weevil, so common in 
oak-timber sections, is identical with the boll weevil. Nothing could 
be a more pronounced error. The two are positively distinct species. 
The boll weevil will not attack acorns, nor does the acorn weevil 
attack cotton for food. ‘The boll weevil flies sparingly at night, nor 
is it attracted to lights, while the acorn weevil flies freely at night at 
certain seasons and is readily attracted to lights. Failure to know 
and observe these differences accounts for the assertion made by some 
otherwise conscientious and reliable persons that boll weevils were 
caught by lamps. In all cases investigated, weevils so caught proved 
to be of the acorn and other species, not boll weevils. 
Then, again, many assert that the sharpshooter is identical with the 
weevil under discussion. As a matter of fact, the insect properly 
called the sharpshooter is not even a weevil, but a leaf hopper, and 
feeds by puncturing and not by biting. Attention is called to these 
popular errors for the reason that some refrain from making war on 
the boll weevil because nothing is done against either of the other two 
insects mentioned. 
EXTERMINATION OF WEEVIL BY CULTURAL METHODS. 
Various methods have been practiced for the destruction of the 
Mexican boll weevil and for the treatment of infested cotton fields. 
Reference will here be made to the remedies found most efticacious by 
the writer as the result of his special investigation of the subject 
during the last two years, which it is hoped may be useful to the very 
large number of persons interested in the cotton industry. 
LAMP TRAPPING. 
The adult boll weevil flies little, if any, at night, and hence lamps 
will trap very few, if any, of them. Numerous tests have been made 
with specially designed lamps, which were so placed in infested fields 
that plants having squares with weevils resting quietly in them might 
be in the direct glare and light of the lamp. In no case did the light 
coax out the weevil from its quiet rest. This practice is entirely 
useless, und the time, labor, and money so expended are totally lost.
