Rst(2)DDT-WIS1labWIS1lab adults show increased resistance to DDT compared to Canton-S flies. Rst(2)DDT-WIS1labWIS1lab larvae show increased resistance to imidacloprid compared to Canton-S larvae, but do not show increased resistance to malathion.
Derived from a field collection in Wisconsin, USA, then the region encompassing Cyp6g1 was removed from the strain via recombination and DDT selection was continued.
Cyp6a8 is overtranscribed in Rst(2)DDT-WIS1WIS1 animals compared to in Canton-S animals.
