RNAi Screening in Spodoptera frugiperda
2016RNA interference is a potent and precise reverse genetic approach to carryout large-scale functional genomic studies in a given organism. During the past decade, RNAi has also emerged as an important investigative tool to understand the process of viral pathogenesis.

Pheromonal Divergence Between Two Strains of Spodoptera frugiperda
Journal of Chemical Ecology, 2013Spodoptera frugiperda consists of two genetically and behaviorally different strains, the corn- and the rice-strain, which seem to be in the process of sympatric speciation. We investigated the role of strain-specific sexual communication as a prezygotic mating barrier between both strains by analyzing strain-specific variation in female pheromone ...

Genome-wide analysis of G-quadruplex in Spodoptera frugiperda
International Journal of Biological Macromolecules, 2023Spodoptera frugiperda (Lepidoptera: Noctuidae) is a globally distributed lepidopteran crop pest that has developed resistance to most insecticides. The G-quadruplex (G4) is a secondary structure in the genome enriched in the promoters for regulating gene expression. However, little is known about G4 in S.

Establishment of a persistent infection of Spodoptera frugiperda nuclear polyhedrosis virus (NPV) in Spodoptera frugiperda (S.f.) cells occurred in three phases: the first phase was characterised by high levels of cell infection and death, the second phase by decreasing cell infection levels leading to the final phase where less than one per cent of ...

Flight performance and metabolism of the moth Spodoptera frugiperda
Journal of Insect Physiology, 1971Abstract Tethered moths were flown continuously for 4 to 7 hr in a sealed flight mill which allowed the trapping of CO2 and the recording of distance flown. The respiratory rate was approximately 10 cal/km per g or 30 cal/hr per g in flight, and 5 cal/hr per g at rest.

Production of rotavirus-like particles in Spodoptera frugiperda larvae
Journal of Virological Methods, 2008A strategy for the production of virus-like particles (VLPs) from simian rotavirus in larvae of the lepidopteran Spodoptera frugiperda is described. VP2 and VP6 coding sequences were co-expressed in larvae co-infected with recombinant baculovirus and these structural proteins self-assembled into VLPs that were secreted and accumulated in the haemolymph.

Curcumin induces autophagic cell death in Spodoptera frugiperda cells
Pesticide Biochemistry and Physiology, 2017The increasing interest in the role of autophagy (type II cell death) in the regulation of insect toxicology has propelled study of investigating autophagic cell death pathways. Turmeric, the rhizome of the herb Curcuma longa (Mañjaḷ in Tamil, India and Jiānghuáng in Chinese) have been traditionally used for the pest control either alone or combination
