Many species of flies, including Sar cophagidae, were killed "by chlor- 
dano 3/^ or 1 pound per acre, applied for the control of grasshoppers. — 
Severin (413). 
Simuliidae 
Slmulium latipes Fries

In tests in Alaska a chlordane-acetone suspension was not effective 
against larvae at 0.5 p. p.m. — Gjullin e_t a^. ( 177 ;. 
In Alaska chlordane proved inferior to DDT, TDE, and methoxychlor 
for the control of "black fly larvae. — Travis (4 58 ). 
Chlordane was tested in the form of a 25-percent emulsion concentrate 
with 65 percent xylene and 10 percent Triton X-100, also as a 10-percent 
solution in Yelsicol AR-50 and fuel oil. Chlordane in fuel oil, at 1.185 
p.p.m./min., or 1:12,700,000 for 15 minutes, gave partial control for a 
short distance from the point of application. — Hocking ^t a^.. ( 220 ) . 
In flume tests on larvae of a "black fly, Sjmulium venustum Say, made 
in the summer of 19^7 in the White Mountains of New Hampshire, chlordane 
did not cause 100 percent detachment at 4 p. p.m. — Kindler and Regan ( 2 61 ) .

Chlordane is ineffective in protecting animals from attack by horse 
flies.— Bishopp and KniplingQ4); Knipling (264). 
Chlordane as a 10-porcent solution in a mixture of Number 1 fuel oil 
and cyclohexanone was applied at the rate of 2 pounds of toxicant per acre 
by a plane which flew at 5 to 20 feet above the tree canopy. The effective- 
ness of the material was determined by counting flies attacking draft 
horses led through the test plots 1 day before spraying and 1, 2, 3 t 5, euad 
7 days after treatment. The results appeared somewhat erratic and no ap- 
preciable effect on fly populations could be demonstrated for any of the 
insecticides tried. Tabanus abactor and T. sulcifrons were the two most 
abundant species. T. atratus . T. vittigpr . T. mul arls. and T. venustus 
were present in small numbers. A few species of Chr ysops and Sjlvjua were 
also present. — Howell e_t al. ( 228 ) . 
Chlordane continues to kill tabanids feeding on livestock for about 
one day after treatment. — U. S. Bur. Ent . and Plant ^uar . ( ^oc ) .
