Adelphocoris superbus (Uhler) 
In tesxs on caged cotton plants, 2*5, 5, and 10 percent DDT gave 
excellent kill.— Loftin (247) « 
Calocoris norvegicus (Gmelin) 
In a field test on strawberries almost 100 percent control was se- 
cured with DDT in aoetone suspension with Tergltol Penetrant 7 at both 
8 and 16 ounoes per 100 imperial gallons of water.— Ross (306) *

A 3-peroent DDT dust and a DDT spray (4 pounds of 10 percent DDT 
in pyrophyllite per 100 gallons of water) greatly reduced -the numbers 
of adults and nymphs on potato plants in western Nebraska*— Hill (209) •

In cage tests DDT proved highly toxic to adults and nymphs* Males 
were killed more quickly than females, and fifth instars apparently as 
readily as third instars. Several hours were required to paralyze or 
knock down the bugs— usually the majority or all were overcome within 
10 to 18 hours, and death generally occurred in 24 to 48 hours. Sprays 
containing DDT at the low rate of 3 l/8 ounces in 100 gallons, or dusts 
at 0.4 percent gave around 100 percent kill in 48 hours in nearly all the 
cage tests. In the field, sprays (6 1/4 ounoes of DDT per 100 gallons) 
and dusts (0.8, 1, and 2 percent) gave highly satisfactory control. The 
residual effect from a single treatment was remarkable both in the in- 
seotary cages and in the field* In the field excellent control was ob- 
tained for 8 weeks from a single treatment*- Underbill (349) • 
Completely controlled with one application of 3-peroent DDT dust and 
reinf ©station did not occur for 6 weeks*— Russell (308) * 
Lygus elisus Van D. 
In the Fhoenix, Aris*, area a 4*6-peroent DDT dust was compared with 
a pyrophyllite dust containing 0*2 percent of pyrethrins to which equal 
parts of sulfur tad been added* These dusts were tested against three 
species of Lygus bugs which all infest sugar-beet seed stooks at the same 
time. In small experimental plots the applications were made at the rate 
of 50 pounds per acre. The pyrethrum dust mixture was applied twice once
