Then used as a stomach poison, DDT in dust form was 69 to 74 times 
as toxio as sodium f luoaluminate, and a spray containing 1/8 pound of 
DDT per 100 gallons of water was about as effective as a spray contain- 
ing 8 pounds of synthetic cryolite (85.4 percent sodium fluoaluminate)© 
The quantity of DDT applied per acre is the important factor affecting 
mortality and not the percentage of H)T contained in the dust. As a 
contact poison dilute sprays containing 1/8 pound or more of DDT per 
100 gallons applied directly to beetles produced net mortalities in ex- 
oess of 60 percent. Adults can accumulate a lethal dose of DDT from 
contact with surfaces treated with sprays or dusts* Fish oil, when used 
in a spray, increased the adhesion of DDT on surfaces exposed to outside 
weathering* The foliage of peanut plants grown in soil containing DDT 
was not toxic to the beetles. In field-cage tests under different 
weather conditions a concentrated spray remained effective longer than 
a dilute spray, and the dilute spray was effective longer than a dust. 
Applications of 50 and 100 pounds of DDT per acre in the upper 3 inches 
of soil gave appreciable mortality of beetles caged on the treated soil. 
No foliage injury was observed on cotton, peanuts, corn, and velvetbeans 
in field plots that received repeated applications of IDT as a 2.5-per- 
cent dust, a dilute spray, and a concentrated spray 9 — Young (381 ) ; also

Preliminary tests indicate that a 1-peroent DDT emulsion controls 
this insect by killing the adult beetles coming to sprayed trees.—

A complete kill of adults in wheat was obtained at the end of the 
first week with a 0.05 percent dosage of DDT. A 3 percent DDT-pyrophyllite 
dust was highly effective after the third week at 15 p.p.ra. of DDT.— 
Cotton _et al. (120 ) • 
DDT (5 and 10 percent in pyrophyllite) when mixed with grain at the 
rate of 1 ounce per bushel gave 100 percent control of grain- infesting 
insects in dry wheat and corn. One-percent DDT at twice this dosage gave 
99.5 percent control in wheat and 95.4 percent control in corn. Two hogs 
were fed corn treated with 10-percent DDT at 1 ounce per bushel. On a 
basis of 100 pounds body weight, each animal consumed about 283 mg. of
