BaS&l try on 1 Jrogg. , a fruit fly 
In Hew South Wales, chlordane proved inferior to DDT, "benzene hexa- 
chloride, and tartar emetic for the control of this fruit fly on plum. The 
chlorinated insecticides were applied as diluted emulsions containing 0.2 
percent of the toxicant at fortnightly intervals at the rate of ahout 1 gal- 
lon per tree. Sugar at the rate of 1 pound per 10 gallons of spray was in- 
cluded with all three chlorinated insecticides to encourage feeding "by the 
flies. The bait spray consisted of 2 ounces tartar emetic and 2.5 pounds 
of sugar in 4 gallons of water, applied at the rate of nearly 9 fluid 
ounces per tree. At harvest the percentages of undamaged fruits were 93«8 
for tartar emetic, 92.3 and 85.9 for the two DDT sprays, 69.7 for benzene 
hexachloride, and 5^»1 for chlordane. — Allman and Friend (l4) . 
^hagoleti s cingulata (Loew) , the cherry fruit fly 
B. fausta (0. S.), the black cherry fruit fly 
Chlordane, 50-percent wettable powder at 1 pound of toxicant per 100 
gallons of water, greatly reduced the infestation, hut failed to meet the 
requirement of 99*5 percent of maggot-free fruit. — Cox (86). 
Rhagoletls pomonella (Walsh), the apple maggot 
In lahoratory tests at the New York Agricultural Experiment Station in 
I9J47 chlordane showed a high degree of toxicity. The rate of kill at the 
higher dosage levels was more rapid than with DDT, although the knockdown 
rate was slower. — Dean (99) .

When dogs were dipped in a 0. 42-percent technical chlordane emulsion 
all fleas were dead in 1 hour. No fleas were found at the end of 24 hours 
on cats similarly dipped. Redipping these cats 7 and 23 days later caused 
no had effect. — Turk and Batte (460).
