Abstract
Solutions of tetramethrin, RU 11679, or cismethrin caused uncoupled convulsions in 30–40 min in exposed thoracic ganglia from S NAIDM house flies at concentrations down to 10 −10 M: whereas these same compounds at 10 −6 M concentrations failed to produce poisoning symptoms when perfused onto the exposed ganglia of the kdr strain of house fly. The pyrethroid analogs examined had a negative temperature coefficient of action on the exposed thoracic ganglia from S NAIDM flies. DDT and GH-74 possessed positive temperature coefficients of action on the exposed thoracic ganglion of susceptible house flies. It is concluded that the central nervous system of the kdr strain of house fly is resistant to pyrethroid action; furthermore, the resistance appears to be widespread throughout the house fly nervous system, involving sensory, motor, and central neural elements.
