The interaction between migration and disease in the Fall Armyworm, 'Spodoptera frugiperda'
… and molecular techniques, this thesis uses the fall armyworm, Spodoptera frugiperda, and its associated baculovirus, S. frugiperda multiple nucleopolyhedrovirus (SfMNPV), as a model system to describe the trade-off between migratory effort and disease susceptibility, and how this affects disease …

The Allatoregulatory Neuropeptides and their Genes in the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)
… and to study the receptor distribution in the fall armyworm.

Rearing density effects on premigrant traits of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
Laboratory and field studies of the fall armyworm, <i>Spodoptera frugiperda</i>, were undertaken to determine if a high larval rearing density produces premigrant traits, and if these traits can be used as criteria for separating nonpremigrant from premigrant groups. An increase in larval rearing …

Control of the release of digestive enzymes in the cricket Gryllus bimaculatus and the fall armyworm, Spodoptera frugiperda
… in the cricket Gryllus bimaculatus and the fall armyworm, Spodoptera frugiperda. 1. Control of enzyme release in the cricket G. bimaculatus. Using flat-sheet preparations of the caecum, digestive enzyme release was investigated. More trypsin, aminopeptidase and amylase are secreted in the …

Contribution of Bacillus thuringiensis cotton cultivars and insecticides to a fall armyworm, Spodoptera frugiperda (J. E. Smith), (Lepidoptera : Noctuidae) management strategy
Fall armyworm, Spodoptera frugiperda (J. E. Smith), response to cottons, Gossypium hirsutum L., expressing Bacillus thuringiensis (Bt) insecticidal proteins, Cry1Ac (Bollgard®), Cry1Ac + Cry2Ab (Bollgard II®), and Cry1Ac + Cry1F (WideStrike™), was evaluated in field and laboratory experiments. In …

Quantifying the effect of fall armyworms on maize yields in a resource constrained economy: A case study in Zambia
Fall armyworm (FAW) is a voracious pest, which has ravaged maize yields in Sub-Saharan Africa since they were first reported in 2016. Their exact impact on maize yields is unclear, with a wide discrepancy in the existing estimates which suffer from potential endogeneity in …

Transcriptional effects of predator cues in the brain of Spodoptera frugiperda (lepidoptera: noctuidae) moths exposed to bat ultrasound
… ultrasound. In this study, I exposed adult male fall armyworm (Spodoptera frugiperda) moths to recorded ultrasonic bat foraging and attack calls for a prolonged period and constructed a de novo transcriptome using RNA-Seq on mRNA extracted from the brains of predator-exposed and unexposed moths. …

Laying technological groundwork for Templated Assembly by Selective Removal (TASR) at biological length scales
… cells derived from the Spodoptera frugiperda (Fall Armyworm) IPLB-SF21-AE cells (with a mean diameter of 15 microns) and mouse-derived non-small lung cancer cells (with a mean diameter of 20 microns) were successfully assembled using TASR onto patterned silicon templates in separate sets of …

Host specific gene expression of the baculovirus, Spodoptera frugiperda nuclear polyhedrosis virus, in insect cell lines
Baculoviruses (family: Baculoviridae) infect insects with high lethality and specificity and are experimental insecticides for suppressing pest populations in the field. Recently, recombinant DNA constructions of baculoviruses have been successfully utilized for the expression of foreign genes. In …
