DLPLOPODA 
Millipedes 
Chlordane, 1 pound per acre, had little effect on millipedes in 
grain fields. — Severin ( 4l4 ) . 
SCOHPIONIDA 
Scorpions 
In Arizona a 2-percent solution of chlordane in oil killed scorpions 
in from 12 hours to 3 days. Chlordane killed more quickly than DDT, hut 
did not last as long. The "best all around mixture for scorpion eradica- 
tion at present seems to he 2 percent chlordane, 10 percent DDT, and 0.2 
percent pyrethrins in an oil spray-hase. — Stahnke ( 437) » 
ORTHOPTERA 
Acrididae 
Grasshoppers are readily killed by the application of chlordane and 
it is used on a large scale for their control. There appears to he little 
difference among species in their susceptibility to chlordane and because
