Lethal and Sublethal Effects of Methoxyfenozide on the Development, Survival and Reproduction on of the Fall Armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) [PDF]

open access: yes, 2011
The lethal and sublethal effects of the ecdysone agonist methoxyfenozide on the fall armyworm, Spodoptera frugiperda (J. E. Smith), were investigated by feeding a methoxyfenozide-treated diet to fifth instars until pupation in doses corresponding to the ...

Evolution of an insect immune barrier through horizontal gene transfer mediated by a parasitic wasp. [PDF]

open access: yes, 2019
Genome sequencing data have recently demonstrated that eukaryote evolution has been remarkably influenced by the acquisition of a large number of genes by horizontal gene transfer (HGT) across different kingdoms.

Flight attraction of Spodoptera littoralis (Lepidoptera, Noctuidae) to cotton headspace and synthetic volatile blends [PDF]

open access: yes, 2015
The insect olfactory system discriminates odor signals of different biological relevance, which drive innate behavior. Identification of stimuli that trigger upwind flight attraction toward host plants is a current challenge, and is essential in ...

Efficacy of the entomopathogenic nematode isolates against Spodoptera littoralis (Boisduval) and Agrotis ipsilon (Hufnagel) (Lepidoptera: Noctuidae)

open access: yesEgyptian Journal of Biological Pest Control, 2021
Entomopathogenic nematodes (EPNs), as biological control agents, have been isolated from many regions throughout the world. Local isolates of EPNs are usually more effective for controlling indigenous insect pests as they are adapted to the local ...

Possible repair of UV-damaged Spodoptera littoralis nucleopolyhedrovirus DNA via generation of mutant carrying photolyase gene with DNA repair activity

open access: yesEgyptian Journal of Biological Pest Control, 2023
Background Baculoviruses can be inactivated by ultraviolet (UV) light, which limits their application as an efficient biopesticide. In an attempt to enhance virus resistance to UV inactivation, a photolyase gene, isolated from Spodoptera litura ...
