Acetylcholinesterase point mutations in European strains of <i>Tetranychus urticae</i> (Acari: Tetranychidae) resistant to organophosphates
5 Nov 2009
Abstract excerpt
BACKGROUND: In Tetranychus urticae Koch, acetylcholinesterase insensitivity is often involved in organophosphate (OP) and carbamate (CARB) resistance. By combining toxicological, biochemical and molecular data from three reference laboratory and three OP selected strains (OP strains), the AChE1 mutations associated with resistance in T. urticae were characterised. RESULTS: The resistance ratios of the OP strains...
