The peach potato aphid Myzus persicae is the most economically important aphid pest in many regions of the world and has developed resistance to many classes of insecticide used for control. In this issue of PLoS Genetics, Puinean et al. made use of recent advances in genomics to quantify the expression of all genes encoding detoxification enzymes in an insecticide resistant strain of M. persicae. Resistance was associated with the over-expression of a single P450 gene, and the authors show, for the first time in an agriculturally important insect pest, that this is due to amplification of the gene.
