Loxostege similalis (Guen.), the garden webworm 
In "barrier and dusting tests a 5-psrcent chlordane dust gave the most 
promising results. — Walton ( 48.3 ). 
In laboratory and cage tests at Waco, Texas during 1946 a 20-percent 
chlordane dust was less toxic than toxaphene, "but the results were con- 
sidered promising. — Ivy and Ewing (237 ).

In preliminary laboratory tests chlordane was much less toxic than

Chlordane dust was promising in tests made in Maine but was not so 
effective as DDT and Eyania. — Hawkins and Thurston (209 ).

Sphingidae 
Protoparce quinquemaculata (Haw. ) , the tomato hornworm 
P. sexta (Johan.), the tobacco hornworm 
Chlordane prepared as a 5-p9rcent dust gave 73 and 30 percent kills, 
respectively, of these two species on tomato, while a 2-percent dust gave 
91 and 43 percent kills. Chlordane in oil emulsion-form at 1:800 gave an 
excellent, but slow kill on the hornworms with 84 percent kill for s . exta 
and 80 percent for the other species. — Gould ( l85 lt 182). 
A 5-percent chlordane dust was the only material that controlled 
full grown larvae of P. qulnquemaculat a on tomatoes in Florida. — 
Kel she imer (248). 
In Ontario chlordane was less effective than DDT which gave good con- 
trol of the tomato hornworm even at 0.72 pounds per acre. — Pox fit. a],.
