SEVEN COTTON INSECT PESTS 
1. In the United States the boll weevil has in some years 
caused a loss in the cotton crop of more than $200,000,000. The 
insect winters as an adult in sheltered places. The weevils that 
survive the winter emerge from hibernation over a long period, 
usually from about March 1 to about July 1, and attack squares 
and young bolls. 
2. The cotton plant bug feeds on many kinds of cultivated 
plants. On cotton it punctures not only leaves and stems, but 
also squares and young bolls, which fall off as a result. 
3. The pink boll worm is a destructive pest of cotton and 
occurs throughout practically all cotton-producing regions of 
the world except in the United States, where it is found only 
in limited parts of Texas, New Mexico and Arizona. 
4. The leaf worm is not known to survive the winter in the 
United States. In some years the moths enter this country, 
usually through Texas, and multiply on cotton throughout the 
growing season, becoming more abundant with each generation, 
and spreading over the main Cotton Belt until they often reach 
the Northern States, and even Canada. This is the worm that 
caused so much destruction to the 1935 Cotton Crop. 
5. The mite known as the red spider has been one of the 
most destructive of cotton pests. The first sign of mite attack 
is a blood-red spot on the upper surface of a leaf; the infested 
leaves turn red or rusty, dry up, and fall; bolls are shed and 
plants may die. This injury, often called “rust” by cotton 
planters, begins about the middle of June and may continue for 
about three months. 
6. Wireworms (Beetle)—The worms are especially troublesome 
because of the fact that they may live in the soil for two and 
possibly three years before transforming into beetles. These 
wireworms bore into seeds or eat the roots of young plants, often 
killing the plants before they have appeared above ground. Af¬ 
fected plants, if not killed, are dwarfed and sickly. Commonly 
the injury occurs in spots in fields; often there are bare spots 
where all the young cotton has been killed. 
7. Cotton Flea Hopper.—The adult hopper is about one-eighth 
of an inch long, pale greenish or grayish, thickly dotted above 
with brownish spots, and with two pairs of characteristic black 
marks near the tip of each wing. The nymphs are green and 
wingless. 
8. We hope the above pictures and short descriptions above 
will help you in identifying these pests when attacking your 
cotton. For more information on insect pests read pages 72

ALORCO CRYOLITE 
ALORCO CRYOLITE, a fluorine in-, 
secticide, has been used by a large 
number of federal and state entomolo¬ 
gists, state experiment stations, inde¬ 
pendent entomologists and individual 
growers. Results from its application 
on tobacco, beans, melons, cucumbers, 
cabbage and potatoes, show it to be 
safe, economical and superior to other 
commonly used insecticides in the 
control of the beetles and worms which 
attack these plants. 
We recommend Alorco Cryolite 
above any other material for control 
of Mexican Bean Beetle. Spraying is the most effective 
method of applying. 
On Peaches and Apples Alorco Cryolite has given excel¬ 
lent results in controlling the worms which attack both; 
however, we advise that you consult your nearest experi¬ 
ment station regarding its use on Peaches and Apples in 
your area. 
WHAT IT CONTROLS— Mexican bean beetles, Bean 
leaf beetles, Flea beetles, Potato beetles, Blister beetles, 
Cucumber beetles, Cabbage worms, Tobacco worms, 
Tobacco flea beetles, Flea weevils, Codling moth, Curculios. 
For dusting Cryolite may be used alone or it may be 
mixed with three to ten parts of flour, sulphur, talc or 
road dust and applied with any suitable dusting apparatus. 
For spraying, two pounds of Cryolite are mixed with 
fifty gallons of water. Sulphur may be added to the spray 
mixture if a fungicide is needed. 
Cryolite should not be mixed with lime. 
Effective control with a minimum of material depends 
on application of a suitable insecticide before the insect 
pest becomes too numerous. Timely applications will pre¬ 
vent loss of crop and hold expenses to a minimum. 
NO INJURY TO FOLIAGE— Severe tests with Alorco 
Cryolite show that it does not injure delicate foliage. 
It has been used on foliage of the following without inju¬ 
rious results: Apples, Peaches, Potatoes, Cabbage, Citrus, 
Beans, Cucumbers, Melons, Tobacco. 
Packed in 6 lb. packages. Price—Post paid, 6 lbs., $1.25; 
24 lbs., $4.00. At Store, 6 lbs., $1.00; 24 lbs., $3.50; 48 lbs.,
