Baseline Susceptibility and Monitoring of Brazilian Populations of <I>Spodoptera frugiperda</I> (Lepidoptera: Noctuidae) and <I>Diatraea saccharalis</I> (Lepidoptera: Crambidae) to Vip3Aa20 Insecticidal Protein

Abstract: The genetically modified maize expressing Vip3Aa20 insecticidal protein from Bacillus thuringiensis Berliner is abiotechnological option for the control of Spodoptera frugiperda (J.E. Smith) and Diatraea saccharalis (F.) in Brazil. To support an Insect Resistance Management program, we conducted studies of baseline susceptibility and monitoring of Brazilian populations of S. frugiperda and D. saccharalis to the Vip3Aa20 insecticidal protein. Neonates were exposed to Vip3Aa20 applied on artificial diet surface.… Show more

“…Sena et al (2009) Diferenças entre as concentrações letais podem ocorrer também em razão de diferentes fases larvais avaliadas nos bioensaios, e de diferentes metodologias e populações. A diferença entre diferentes populações ocorre em razão da variabilidade genética natural das espécies (Bernardi et al, 2014).…”

“…The control treatment was composed of distilled water and surfactant. This concentration represents approximately two-fold value of LC 99 for S. frugiperda populations, and it was considered a diagnostic concentration (Bernardi et al, 2014).…”

“…The diet surface in each well was 1.5 cm 2 . This concentration was previously validated as a diagnostic concentration for resistance monitoring of S. frugiperda in Brazil (Bernardi et al, 2014). The control treatment was composed of distilled water and surfactant.…”

“…For S. frugiperda and D. saccharalis, also in Brazil, two diagnostic concentrations of 2.0 and 3.6 µg Vip3Aa20/cm 2 were defined for monitoring resistance, these caused up to 90% mortality (BERNARDI et al, 2014). Therefore, H. zea can be considered less susceptible than S. frugiperda and D. saccharalis to Vip3Aa20 protein in Brazil.…”

“…Phenotypic or genotypic methods can be used for resistance monitoring (ANDOW; ALSTAD, 1998;ANDOW et al, 1998, ANDOW 2008. Among these methods, one of the most used is the phenotypic method of screening field-collected larvae (SIMS et al, 1996;WU;GU;HEAD, 2006;BERNARDI et al, 2014). In this method, neonates are exposed to a diagnostic concentration of the insecticidal protein incorporated in the diet or applied in its surface.…”
