HEMIPTERA 
Coreidae 
Anas a tristis (Deg.), the squash "bug 
In a laboratory test a 5-percent chlordane dust caused 100-percent 
knockdown and 85.7-percent mortality of the hugs in 4-8 hours. A 2.5- 
percent chlordane dust was almost as effective, causing 95-percent knock- 
down and 75-percent mortality in the same time. In a field-cage test 5- 
percent chlordane caused 80. 6-percent mortality. — Walton ( 483 ) . 
DDT was relatively ineffective as compared with chlordane when 
applied to the adult squash "bug in the form of aqueous sprays as well as 
dusts. — Kearns et al. ( 245 ). 
Leptocoris trivittatus (Say), the hoxelder hug 
A 2-percent emulsion spray of chlordane killed 97 percent of the 
insects within 48 hours and showed residual action. — Munro and Post ( 33 ?,) » 
Leptoglossus gonagra (F.). the citron plant hug 
In Florida this hug was controlled hy 30 to 40 pounds of a 5-percent 
chlordane dust per acre or 0.6 pound of 50-percent wettahle chlordane per 
100 gallons of water. — Thompson and Griffiths ( 454 ). 
Lygaeidae 
Blissus, leucopterus (Say), the chinch hug 
In tests made in Connecticut chlordane gave the "best control, 
followed hy DDT-sahadilla mixture and DDT alone. Chlordane, applied to an 
infested lawn as a 5 percent dust at the rate of 5 pounds to each 1,000 
square feet, destroyed "both adult and immature hugs in 24 hours and its 
residual action persisted for two to three months or longer. — Scliread 
( 406 . 408).

Nysius ericae (Schill.), the false chinch hug 
In small-scale tests 5 percent chlordane dust gave 100 percent kill 
in 48 hours. — Smith (425). 
Oncooeltus fasciatus (Dall.), the large milkweed hug 
Adults in hattery jars were exposed to chlordane vapor. At the end 
of one day the mortality was 66.6 percent and at the end of two days it 
was 100 percent. — Dustan et, al. ( 12 1 ) . 
See under Blattella germanica. — Srown, Wenner, and Park (53) .
