Abstract excerpt

The beet armyworm, Spodoptera exigua (Hübna) is a serious agricultural pest that is challenging to control due to resistance to most pesticides, including pyrethroids. This resistance has previously been linked to the knockdown resistance (kdr) mutation (L1014F) of the voltage-gated sodium channel (VGSC) in S. exigua. To better understand the frequencies of the kdr mutation of SeVGSC and identify the evolutionary...
