To obtain a genetically more homogeneous strain for resistance to fenitrothion, adults of Akita strain were selected for 17 successive generations with this insecticide. After the selections, the resistance ration of established Akita-f strain to susceptible SRS strain was about 4, 000. Crosses between Akita-f and SRS strains showed that fenitrothion resistance was almost completely dominant. Linkage group analyses for the dominant factor were carried out usin two multi-chromosomal marker strains. The dominant factor(s) for fenitrothion resistance was associated only with the 2nd chromosome. At the same time, these crossing experiments unintentionally revealed that the male determining factor, M, was linked to the 3rd chromosome in this resistant strain.
