an additional amount over the top of the soil and around the base of the 
tree. The leaf eating or agricultural ants can he controlled by sprinkling 
the chlordane dust over the whole surface around the entrance to the nest. — 
Thompson and Griffiths (Mb). 
A 2-percent spray of chlordane was recommended by the U. S. Bureau of 
Entomology and Plant Quarantine (j££L) in August 19^+9 for the control of 
ants. Apply it directly into cracks or openings frem which ants are emerg- 
ing, and onto the surfaces immediately surrounding those openings. Then 
they will have to crawl over the deposit of insecticide that remains. 
Chlordane spray can also be applied directly to the nests of ants. 
A mixture of lindane and chlordane has been suggested to accomplish 
both quick kill of ants and to have long-lasting residual action. —

Liriomyza flaveola (Fall.), the serpentine leaf miner 
A 5-percent chlordane dust gave the most effective field control of 
this insect attacking tomatoes in Florida.— Kel she imer ( 248 ) . 
Sprays containing from 1 to 2.25 pounds of chlordane per 100 gallons 
and a 5-percent chlordane dust (7»5 pounds toxicant per acre) gave satis- 
factory control of this insect on field grown asters in southern California. — 
Jefferson and Pence ( 239 . 240 ) . 
Chlordane 50-percent wettable powder at 2 pounds per 100 gallons of 
water was inferior to parathion and toxaphene against the serpentine leaf- 
miner attacking tomatoes in the Florida Everglades. — Hayslip ( 212 ). 
In a large plot test in southern Florida in 19^7 chlordane emulsion 
(81 percent) at 2.3 pounds toxicant per 100 gallons of water gave 97 percent 
control of the serpentine leaf miner on potatoes. — Wolfenbarger ( 508 ) . 
Liriomyza orbona (Meig.), the pea leaf miner 
Five applications of a 5-percent chlordane dust, applied by means of 
a power driven duster at the rate of 26 pounds per acre for each application, 
gave 98 percent control. Laboratory tests using known deposits of chlordane, 
benzene hexachloride, DDT, and hexaethyl tetraphosphate indicated that chlor- 
dane was the most effective, killing 100 percent of the adult flies in 16 
hours with a dosage of 2 micrograms per 10 square inches of surface. — Lange 
and Smith (283).
