Identification of an alternative knockdown resistance (<i>kdr</i>)‐like mutation, <scp>M918L</scp>, and a novel mutation, <scp>V1010A</scp>, in the <i>Thrips tabaci</i> voltage‐gated sodium channel gene

Abstract

We have characterized a known kdr mutation and identified a novel mutation in the voltage-gated sodium channel gene of Thrips tabaci associated with resistance to lambda-cyhalothrin. This gene region and these mutations are expected to be useful in the development of a diagnostic test to detect kdr resistance in many onion thrips populations.
