Rdl insect
WebThe insect γ-aminobutyric acid (GABA) receptor RDL (resistance to dieldrin) plays a central role in neuronal signalling and is the target of several insecticide classes. 1 It is a member of the Cys-loop ligand-gated ion channel (CysLGIC) gene superfamily, which consists of receptors comprising five subunits arranged around a central ion channel … WebSep 25, 2013 · One or more mechanisms may be involved in physiological resistance, including alteration of target site nerve receptors (e.g., kdr, Rdl and Ace. 1R) and detoxification via increased enzyme activity of non-specific esterases, glutathione S -transferases and P-450 mediated monooxygenases (mixed function oxidases) [ 20 ].
