unidentified species 
A 5-percent chlordane dust applied for the control of the serpentine 
leaf miner on asters controlled whitefly, hut was inferior to a EHC dust 
(0.75 percent gamma content) for this purpose. — Jefferson and Pence ( 239 ) . 
Aphidae 
Anur aphis per sicae-niger (Smith), the "black peach aphid 
In Oregon a 2-percent chlordane dust killed only 18.5 percent of 
these aphids on peach trees. — Jones and Rosenstiel (244). 
Aphis gossypii Glov. t the cotton aphid, the melon aphid 
In lahoratory and cage tests at Waco, Texas in 1946, chlordane gave 
promising results against cotton aphids. — Harned ( 205 ) . 
At 10- and 20-percent concentrations chlordane dust was effective 
against cotton aphids, hut not quite so effective as corresponding con- 
centrations of toxaohene , or BHC (gamma isomer 5*75 percent). — Ivy and 
Swing (237). 
At Florence, South Carolina in 1947, 10- and 20-percent chlordane 
dusts gave good control of cotton aphid, hut a mixture of 10-percent 
chlordane and 5-percent DDT permitted a build-up of aphids in one 
test. — Eondy (41) . 
A 5-percent chlordane dust did not affect the aphid population. — 
Arant (20). 
At a dilution of 1 to 300 of an emulsion concentrate containing 20 
grams of insecticide per 100 ml., chlordane was slightly less toxic than 
technical grade DDT to the melon aphid of various ages. — Sun e_t a^. ( 450 ) , 
In additional tests these workers ( 449 ) used the melon aphid as a test 
insect to evaluate different chlordane formulations. 
Chlordane 25-percent emulsion at 1:400 was unsatisfactory in con- 
trolling aphids (chiefly this species) on celery in Florida in 1948. Ho 
injury to celery plants was ohserved. — Wylie (514 ). 
Aphis fahae Scop. , the hean aphid 
Mixtures of nicotine and chlordane dusts tend to produce mortalities 
slightly exceeding those to he expected from similar joint action, hut 
the differences may not he great enough to prove synergistic action. At 
the 50-percent mortnlity level nicotine is 1.49 times as toxic as chlor- 
dane; at the 90-percent level nicotine is 1.43 times as toxic as chlor- 
dane. — Sun ( 445 ).
