High γ-aminobutyric acid content, a novel component associated with resistance to abamectin in Tetranychus cinnabarinus (Boisduval)

▶ Identifying a novel biochemical and physiological mechanism of resisting abamectin in T. cinnabarinus. ▶ Presenting evidence that the elevated but stable GABA levels in T. cinnabarinus conferring resistance to abamectin. ▶ Finding that the resistance to abamectin mediated by high GABA content in T. cinnabarinus cost its decrease of crawling speed.
