Genetic basis of Spodoptera frugiperda (Lepidoptera: Noctuidae) resistance to the chitin synthesis inhibitor lufenuron

Abstract

Based on genetic crosses, the inheritance pattern of lufenuron resistance in S. frugiperda was autosomal, incompletely recessive and polygenic. Implications of this finding to IRM are discussed in this paper.

Selection and characterization of the inheritance of resistance of Spodoptera frugiperda (Lepidoptera: Noctuidae) to chlorantraniliprole and cross‐resistance to other diamide insecticides

“…the resistance loci are in autosomal chromosomes. As in most cases of insecticide resistance, other studies have reported autosomal resistance of S. frugiperda , to lambda‐cyhalothrin, carbaryl, lufenuron and spinosad . For the diamide insecticides, the resistance of P. xylostella and T. absoluta was characterized as autosomal and incompletely recessive dominance …”

Managing fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), with Bt maize and insecticides in southern Brazil

“…These insecticides have also been effective against FAW when used on non‐Bt maize in the central‐western region in Brazil and in the USA . However, it is worth mentioning that a high frequency of resistance to spinosad, lambda‐cyhalothrin and lufenuron has already been detected in Brazilian populations of FAW . In contrast, a low frequency of resistance to chlorantraniliprole has been reported in the same populations .…”

“…In addition, intensive maize cultivation in some regions of Brazil also contributes to the rapid evolution of resistance to insecticides in FAW populations. In these crop production systems, FAW has evolved resistance to several insecticides, such as lambda‐cyhalothrin, chlorpyrifos, spinosad and lufenuron …”

Bases genéticas e moleculares da resistência de <i>Spodoptera frugiperda</i> (J.E. Smith) (Lepidoptera: Noctuidae) a spinosad

“…Sua descoberta teve origem a partir de um programa de seleção de produtos naturais, testando extratos de solo fermentados com potencial de utilização na agricultura e/ou na indústria farmacêutica (THOMPSON et al, 2000). Até o presente momento existem dois produtos comerciais à base de espinosinas no (YU, 1991(YU, , 1992(YU, , 2006CARVALHO et al, 2013;NASCIMENTO et al, 2015). Com a evolução da resistência de S. frugiperda aos inseticidas convencionais, tais como piretroides, organofosforados, carbamatos e inibidores da biosíntese de quitina, as espinosinas se tornaram uma opção para o controle desta praga no Brasil.…”

“…Only one synonymous mutation within the two strains (G567A) was found, showing that the 6 is not the only subunit involved in S. frugiperda resistance to spinosad.
