Insecticidal activity of synthetic amides on Spodoptera frugiperda.
The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated. The most active amide was N-[3-(3',4'-methylenedioxyphenyl)-2-(E)-propeno...
متن کاملInsecticidal and growth inhibiting action of the supercritical extracts of Melia azedarach on Spodoptera frugiperda
This study evaluates the effects of supercritical carbon dioxide extracts obtained from the fruit of Melia azedarach L. (Meliaceae) on the development of Spodoptera frugiperda J.E. Smith, 1797 (Lepidoptera: Noctuidae), from the larval period until the insect adulthood. For this purpose, a laboratory-scale extraction unit was operated at 60 °C and 200 bar. Larval mortality increased by raising t...
متن کاملImpact of Spodoptera frugiperda neonate pretreatment conditions on Vip3Aa19 insecticidal protein activity and laboratory bioassay variation
BACKGROUND Variation in response to insecticidal proteins is common upon repetition of insect bioassays. Understanding this variation is a prerequisite to detecting biologically important differences. We tracked neonate Spodoptera frugiperda (J.E. Smith) susceptibility to Vip3Aa19 over 17 generations using standardized bioassay methods. Five larval pretreatment conditions and one bioassay condi...
متن کاملFunctional and structural characterization of DNMT2 from Spodoptera frugiperda.
Dear Editor, DNA methylation is one of the most important epigenetic marks and plays a central role in gene silencing in high eukaryotes. It is established by DNA methyltransferases (DNMTs), which are classified into three subfamilies. In contrast to DNMT1 and DNMT3, the biological function of DNMT2 remains elusive to date. DNMT2 was first identified in mouse and human and appears to be well co...
متن کاملA new ascovirus from Spodoptera exigua and its relatedness to the isolate from Spodoptera frugiperda.
A new ascovirus was isolated from Spodoptera exigua in Indonesia and was tentatively assigned as a new species, Spodoptera exigua ascovirus 5a (SeAV-5a) according to the present ICTV ascovirus naming scheme based on DNA restriction fragment length polymorphism (RFLP), hybridization, formation of occlusion body, tissue tropism and host spectrum. SeAV-5a replicated primarily in the fat body of su...
