In 1944 cabbage in the Kenosha, Wise*, area was treated with dusts 
containing 3 percent of DOT, 0.5 percent rotenone, or 20 percent of 
oaloium arsenate. The DOT dust gave the best control and the average 
weight of the cabbage heads was greatest in the DOT- dusted plots. A 
spray containing 2 pounds of DOT (Gesarol AK-20) per 100 gallons of 
water gave better control than a cube spray or a lead arsenate spray 
each containing 4 pounds per 100 gallons.— Allen and Brunn (j[l) •

Phaloniidae 
Anticargla gemnatilia (Hbn.), * ne velvetbean caterpillar 
Excellent control of this caterpillar on peanuts and soybeans was ob- 
tained with a single application of 3"P«rcent DDT dust or a DDT spray.-

Acrobasis caryae Grote, the pecan nut casebearer 
A 0.20-percent DDT spray reduced infestation by about one-third.- 
Hamilton (200). 
Gesarol SH-5 a t 1/2 gallon per 100 gallons of water, and Gesarol A-20 
at 2 pounds, reduced the infestation to Uh and Uo percent, as compared with 
60 percent in the checks. Timing the sprays with hatching is very important.

Hesults obtained with DDT were promising enough to warrant further 
tests.— Baker and Porter (81) . 
Ephestia elutella (Hbn.), the tobacco moth 
In laboratory experiments at Hichmond, 7a. , undiluted DDT was used 
in an acetone-oil solution. The solution was atomized into a modified Peet- 
Grady chamber. The test Insects were adults of the tobacco moth and the 
cigarette beetle. A 5 percent DDT-oil solution, used at the rate of 100 cc. 
per 1,000 cubic feet, resulted in 97 percenv kill of the tobacco moth in 
3 days and 71 percent kill of the cigarette beetle in 5 clays, a 15-percent 
solution killed 98 and 90 percent of the moths and beetles, whereas pyreth* 
rum-oil spray (0.2 percent of pyrethrins) gave mortalities of 100 and U6 per- 
cent of the moth and beetle, respectively. A 10-percent DDT dust mixture, 
prepared by mixing pyrophyllite with an oil solution of DDT and then blown 
into the dust chamber at the rate of 3 ounces per 1,000 cubic feet, killed 
Us percent of the tobacco moths and 93 percent of the cigarette beetles. A
