Sprays and dusts containing rotenone or copper-rot enone were 
recommended for the Mexican bean beetle in victory gardens in 
Indiana*— Reed (496) . 
In tents of doaage for equal oontrol at the 90 percent level 
for larvae, # 16 peroent of pyrethrins equalled 0.08 percent of rote- 
none in derris duet* In dosage studies to compare two diluents for 
d err is, the dosage-response curves for protection of bean foliage 
from injury were much flatter than the curves for actual control 
of "the bean beetle. One part of derris suitably diluted with pyro- 
phyllite is as effective as 2.5 to 5 parts of derris diluted with 
clay* Dusts or sprays of rotanone should be applied to the under 
surfaoe of -the bean leaves.— Turner (602 , 604); Turner and Horsfall 
(607) . 
Dusts containing 2 percent of Lethane and 0.4 peroent of rote- 
none were as effective as dusts containing 0.75 to 1 percent of 
rotenone.— Anonymous (8, 9). 
In 1944 rotenone was still recommended against the Mexican 
bean beetle in viotory gardens, although as partial substitutes cryo- 
lite, pyrethrum, calcium arsenate, magnesium arsenate, zinc arsenite, 
barium fluosilicate, pnd sodium fluosilicate could be used under 
certain conditions .-^Thite and Doolittle (683) j U. S. Department of 
Agriculture (632 , p. 15). 
Cucujidae 
Orytaephilus Surinam ens is (L.), the saw-toothed grain beetle 
Adults are susceptible to the rotenone class of insecticides.

Curoulionidae 
Anthononus eugenii Cano, the pepper weevil 
A cryolite-tale-cube dust mixture was used at the rate of 15 
to 25 pounds per acre per application in California. The treated 
fields produced more than three times as many pods as the untreated 
fields. It was estimated that 3,570 acres of peppers were treated, 
bringing the total net profit to $594,370. The use of calcium arse- 
nate to control the pepper weevil caused increases in aphid popula- 
tions.— Campbell and Elmore (102) ; Elmore and Campbell (163 ).
