A genetical study of DDT resistance in the mosquito Aedes aegypti

Crosses have been carried out to determine the relationship between adult DDT resistance and the three linkage groups of the mosquito Aedes aegypti. Two linkage groups were implicated in the control of DDT resistance. In the Bangkok-HR strain resistance derived mainly from linkage group III, probably with the maor effect from the gene R-DDT2. When resistance was transferred into a susceptible background, by outcrossing Bangkok-HR to strain 64 and reselecting, resistance in the resulting Bangkok-MR strain came from both linkage groups II and III.
