The relative rates of cytochrome P-450 selection in southern Mexican Anopheles albimanus populations were investigated during a 3 years indoor residual house spraying intervention with a pyrethroid (PYR) or DDT, a mosaic of organophosphate (OP)-PYR, and the annual rotation of OP-PYR-carbamate (CARB). This insecticide resistance mechanism, initially evenly spread in the mosquito population, correlated with PYR resistance during the second treated year, when cytochrome P-450 contents increased in most villages of the PYR, rotation and mosaic schemes. However, by the third year, mean cytochrome P-450 contents declined to susceptible levels in mosquitoes of the rotation and one mosaic group but not in the PYR-treated villages. In DDT-treated villages, a continuous decrement of cytochrome P-450 levels occurred since the first treatment year, and susceptible levels were observed at the end of the intervention. Most correlations of cytochrome P-450 levels and PYR resistance were lost during the third year, indicating that another mechanism evolved in resistant mosquito populations. (C) 2007 Elsevier Inc.
