• The mixtures of furamethrin and piperonyl butoxide in acetone were applied topically to adults of the housefly, Musca domestica L. The dosage-mortality relations were analysed by fitting a mathematical model proposed by HEWLETT (1969) to the data, y=a+b_1 log z_1+b_2z_2/(c+z_2) where y is probit mortality, z_1=100×dose of furamethrin, and z_2=dose of piperonyl but-oxide; a, b_1,b_2 and c are parameters. The model was fairly applicable to the data, and a mixture with an indefinitely large ratio of piperonyl butoxide was estimated to be 9.35 times as toxic as furamethrin alone.
