A study of dieldrin in the house fly central nervous system in relation to dieldrin resistance.

Abstract

In general, there are no large differences in the rate of uptake of C14-dieldrin by the central nervous systems of susceptible or dieldrin-resistant female house flies, Musca domestica L., following injection or infusion. No evidence could be found that binding of dieldrin to tissues within the central nervous system is a significant factor in resistance. Metabolism of dieldrin within the same tissues was not detectable in either strain. Dieldrin resistance in house flies may be largely due to insensitivity at the receptor site.
