title: Mode of inheritance of dieldrin resistance in Anopheles farauti No. 1 and A. farauti No. 2.
abstract: The mode of inheritance of dieldrin resistance was studied in Anopheles farauti No. 1 and A. farauti No. 2. In both these species a susceptible strain was crossed with a resistant strain and F1 individuals backcrossed to the susceptible parental strain. After exposure to 0-4% dieldrin for one hour the survivors were again backcrossed to the susceptible. After successive backcrosses it was found that in both species dieldrin resistance was determinded by a single, semi-dominant gene which was not sex-linked.
