Anagrapha faloifera (Kirby), the oelery looper 
This insect was completely controlled with one application of DDT, 
and reinfestation did not oocur for 5 weeks.— Russell (308 ) * 
Caenurgina sp» 
Examination of the ground under hairy vetch at Oregon City, Oreg., 
disclosed that a 5-percent DDT dust had killed insects of this species.

Heliothls armigera (Hbn.), the corn earworm, the tomato fruitworm, the 
Dollworm 
DDT was the only insectioide whioh proteoted the corn until harvest- 
tins* DDT in mineral oil gave almost complete control of the corn earworm 
in both the green and the maturing stages of the corn ears* Pyrethrum, 
styrene dibromide, and dichloroethyl ether were all less effective* Two 
highly refined mineral oils were used, Bayol (80-90 sec* Saybolt) and 
Superla No* 13 (120-125 sec* Saybolt)* £aoh inseotioide was tested in 
both oils, in the following concentrations : DDT 2, pyrethrum extraot 
(0*2 percent pyrethrins), dichloroethyl ether 2, and styrere dibromide 
1 percent* They were applied at two dosages, 0*6 and 1*2 ml* of solution 
per ear*— Blanchard and Satterthwait (88)* 
"When silks of sweet corn were dusted heavily with Gesarol A-3, the 
reductions in wormy ears were 50, 40, and 30 percent in three tests*— 
Bwart (145)* 
In testing six methods of ear treatment the DDT- dusted plot had 
3*56 of percent infested ears as against 7*26 peroent in the oheok and 
only 0*99 percent in the oil treatment*— Granovsky ( 187 ) • 
A 3-peroent DDT dust applied to the silks was effective.— Haseman 
(£03). 
Three applications of Gesarol A-3 dust to cotton showed only 8.3 
peroent repellency against ovipositing moths.— Fletcher and Thomas (156 ) ♦ 
Dusting the silks of sweet corn with a 3 percent DDT dust materially 
reduced earworm infestation. Of 59 treated ears 32.2 percent were in- 
jured, whereas 86.2 peroent of 65 untreated ears were injured.— 
Cartwright (108) . 
DDT in the form of an aqueous suspension (0.5 pound) or an emulsion 
(1 pound per 100 gallons of water) gave perfect control of tomato fruit 
worms*— Owens (284)*
