Oxidative metabolism pyrethroid insecticides

Mixtures of PBO with pyrethroid or carbamate insecticides are often more effective against insect strains resistant to these compounds where oxidative metabolism is responsible for the decreased effect (Davies et at., 1958 Wilkinson, 1968 Glynne-Jones, 1983 MacDonald eta ., 1983 h unaki etai. 1986). There is no evidence to indicate that PBO increases the low toxicity of pyrethrins and pyrethroids l<> mammals. The acceptable daily intake (ADI) of PBO for humans has been established at 0.2 mg per kg body weight (JMPR, 1995),...
