Inheritance, fitness cost and mechanism of resistance to tebufenozide in <i>Spodoptera exigua</i> (Hübner) (Lepidoptera: Noctuidae)

Abstract

Tebufenozide resistance in S. exigua was inherited as autosomal, incompletely recessive and controlled by more than one gene. Development of the resistance may cost significant fitness for the resistant population. Mixed-function oxidases might play an important role in tebufenozide resistance in S. exigua. This study provided valuable information for further understanding tebufenozide resistance and for facilitating the development of resistance management strategies.
