DDT-RESISTANCE AND DIELDRIN-RESISTANCE IN ANOPHELES QUADRIMACULATUS.
The nature and mode of inheritance of both DDT-resistance and dieldrin-resistance in Anopheles quadrimaculatus from the United States of America have been studied. Dieldrin-resistance is shown to be dependent on a single, semi-dominant, genetic factor, and DDT-resistance on a single, recessive one, though the expression of this latter factor is to some extent dependent on the genetic background. Both resistances can occur in the same mosquito but can be separated, thus indicating the independent nature of the two genetic factors involved.
