It is well known that chlorinated hydrocarbon insecticides are present in tissues and eggs of birds that receive these chemicals in their diets. Some workers, for example Gene11y and Rudd (1956) and DeWitt (1956), studied the effects of different levels of ingested insecticides on the reproduction of game birds. Additional studies are needed to relate the amount of insecticide in the diet to the level in the egg and that in turn to reproduction and effects on young birds. Work on pheasants is of special interest at South Dakota Experiment station because of the economic importance of this game bird to the state. Since dieldrin and aldrin have been used to control corn root worm on much of the prime pheasant range, and since dieldrin is a metabolite of aldrin (Bann et ale 1956), the experiment reported herein vas carried on to study the residues of dieldrin in pheasants. The objectives were to determine and compare: (1) the trend of dieldrin deposition in yolks of eggs from hen pheasants ted different levels of the insecticide, (2) the trend of dieldrin deposition in the egg yolks after termination of treatment, and (3) the level of dieldrin in the fat of the birds after the egg laying period. This work is one phase of an extensive study on the relationship of insecticides to pheasants.","abstract_html":"At present, there is considerable interest in the effects of insecticides upon our wildlife populations.
