Toxicity of chlorinated insecticides to quail and pheasants

January 1, 1956

'Residues from insecticidal applications of chlorinated hydrocarbons may remain toxic for extended periods. In experiments designed to furnish information on the effects upon quail and pheasants of prolonged feeding upon diets containing small percentages of these compounds, it was shown that aldrin, dieldrin and endrin are cumulative, and that quail are unable to survive after ingesting 5-10 mg./kg, of aldrin, 30-50 mg./kg, of dieldrin, or 6-15 mg./kg, of endrin. Maximum levels (p.p.m.) in the diets permitting survival for extended periods were: DDT, 200; strobane, above 500; aldrin, 0.5; dieldrin, 1.0; endrin, 1.0. Inclusion of these compounds in the diets of breeding quail and pheasants affected hatchability of eggs and viability of chicks, even though the adult birds appeared unaffected.' Detailed figures are given for all points mentioned.
