Miridae 
Adeloph o coris lineolatus (Goeze), the alfalfa plant bug 
A. raoidus (Say), the rapid plant bug 
Chlordane wettable powder and emulsion at 1 pound of toxicant per 
acre cave very good control of these insects in alfalfa in Wisconsin. In 
tests of spraying equipment very good control of forage insects was ob- 
tained at 30 to 40 pound pressures and 15 to 30 gallons per acre. The 
method of application appears to be secondary to dosage per acre of the 
toxicant. — Medler and Chamberlin ( 320 ) . 
Dicyphus minimus Uhl, the suckfly 
A 5-?srcent chlordane talc dust was effective against suckfly 
tomato in the lower Rio Grande Valley in 1949. Nine days after lusting 
the number of suckflies in 20 net sweeps was reduced from 601.7 on un- 
treated plants to 7 on plants treated with the chlordane dust. — w ene ( 494 ) . 
Lygus ellsus Van Duzee 
In tests made on alfalfa plots in Arizona in 1947 and 1948 one 
pound of chlordane was almost as effective as 1.25 pounds of DDT. The 
average Lygus reductions were 91 percent with chlordane and 92 percent 
with DDT. Dusts, emulsions, and suspensions of chlordane were equally 
effective.— Russell (4Ql). 
Lygus hesperus Knight 
A 5-percent chlordane dust was less effective than a 0.5 percent 
parathion dust. — Smith (42^) . 
Same as for Lygus elisus . — Russell ( 401 ) . 
Lygus obi ineatus ( Say ) , the tarnished plant bug 
Chlordane showed some promise against tarnished plant bug. — Biahopp 
Q2); Gould (186). 
In cage tests at Tallulah, Louisiana a 20-percent chlordane dust 
killed 60 percent of these bugs in one test and 66 percent in another 
test. The highest chlordane mortalities were caused by a dust containing 
10 percent chlordane plus 2.5 percent parathion (93 percent kill) and by 
a mixture of 10 percent chlordane plus 5 percent DDT (34 percent kill). — 
Scales and Smith (403). 
In laboratory tests a dust containing 1 percent chlordane killed 
95 »3 percent of the adults in 2 days, whereas a dust containing 3 percc 
1 grade DDT killed only 54 percent. — Sun e_t al. ( 4$ Q) . 
Chlordane did not give as good results as DDT and EHC, although a 
combination of this material with DDT showed promise. — Pederson ( :o0 ) .
