The new carbamate insecticide, Sevin, has a low toxicity against houseflies. However, it is activated effectively by low concentrations of Sesoxane, a pyrethrum synergist. This occurs with normal nonselected flies and also with strains selected for resistance to DDT and Parathion, which have considerable cross resistance to Sevin.
