Abstract

Insecticide resistance is a paradigm of microevolution and insecticides are responsible for the strongest cases of recent selection in the genome of Drosophila melanogaster . Here we use a naïve population and a novel insecticide class to examine the ab initio genetic architecture of a potential selective response. Genome wide association studies of chlorantraniliprole susceptibility reveal variation in a gene of major effect, Stretchin Myosin light chain kinase ( Strn-Mlck ), which we validate with linkage mapping and transgenic manipulation of gene expression. We propose that allelic variation in Strn-Mlck alters sensitivity to the calcium depletion attributable to chlorantraniliprole’s mo..
