A glutathioneS-transferase (BdGSTd9) participates in malathion resistance via directly depleting malathion and its toxic oxide malaoxon inBactrocera dorsalis(Hendel) Ghent University
BACKGROUND The oriental fruit fly,Bactrocera dorsalis(Hendel), is a widespread agricultural pest that has evolved resistance to many commonly used insecticides including malathion. GlutathioneS-transferases (GSTs) are multifunctional enzymes that metabolize insecticides directly or indirectly. The specific mechanism used by GSTs to confer malathion resistance inB. dorsalisis unclear. RESULTS BdGSTd9was identified fromB. dorsalisand was expressed ...
