Abstract:When pressured with DDT at a level producing 20–80% mortality for 6 generations, a wild population of Drosophila melanogaster Meigen developed over 1000-fold resistance to DDT (Geneva-R-Low strain). Higher pressure for fewer generations (Geneva-R-High strain) also yielded virtual immunity to DDT. However, selection of a laboratory-reared population at the LD80 level for 4 generations (TK-I-R strain) produced male flies that demonstrated only a 40-fold increase in resistance to DDT whereas female flies showed an 80-fold increase. Although the TK-I-R insects were cross resistant to chlorpyrifos (10X) and possibly methomyl (2–3X), no cross resistance to either insecticide occurred with the Geneva-R-Low or Geneva-R-High strains. In the Geneva-R-High insects, DDT resistance was found to result primarily from a semidominant 2nd chromosomal factor with support from additional semidominant factors on chromosomes 1 and 3.
