Parasitic Manipulation of Host Behaviour: Baculovirus SeMNPV EGT Facilitates Tree-Top Disease in Spodoptera exigua Larvae by Extending the Time to Death

Insects, 2015
Many parasites enhance their dispersal and transmission by manipulating host behaviour. One intriguing example concerns baculoviruses that induce hyperactivity and tree-top disease (i.e., climbing to elevated positions prior to death) in their ...

Partial Alleviation of Homologous Superinfection Exclusion of SeMNPV Latently Infected Cells by G1 Phase Infection and G2/M Phase Arrest

Viruses
Viral infection can regulate the cell cycle, thereby promoting viral replication. Hijacking and altering the cell cycle are important for the virus to establish and maintain a latent infection. Previously, Spodoptera exigua multiple nucleopolyhedrovirus (

Spodoptera exigua Multiple Nucleopolyhedrovirus Increases the Susceptibility to Insecticides: A Promising Efficient Way for Pest Resistance Management

Biology, 2023
Spodoptera exigua is a polyphagous pest of diverse crops and causes considerable economic losses. The overuse of chemical insecticides for controlling this pest results in insecticide resistance, environmental pollution and toxicity to other non-target ...

Study on Physical Properties of Four pH Responsive Spodoptera exigua Multiple Nucleopolyhedrovirus (SeMNPV) Microcapsules as Controlled Release Carriers

Scientific Reports, 2022
This study provides a promising controlled release form of nuclear polyhedrosis virus (NPV) for targeted control of lepidopteran pests. However, the application of NPV is limited due to its sensitivity to UV inactivation. This study investigated the anti-

Co-infection with iflaviruses influences the insecticidal properties of Spodoptera exigua multiple nucleopolyhedrovirus occlusion bodies: Implications for the production and biosecurity of baculovirus insecticides. [PDF]

PLoS ONE, 2017
Biological insecticides based on Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) can efficiently control S. exigua larvae on field and greenhouse crops in many parts of the world. Spanish wild populations and laboratory colonies of S. exigua are

Iflavirus Covert Infection Increases Susceptibility to Nucleopolyhedrovirus Disease in Spodoptera exigua

Viruses, 2020
Naturally occurring covert infections in lepidopteran populations can involve multiple viruses with potentially different transmission strategies. In this study, we characterized covert infection by two RNA viruses, Spodoptera exigua iflavirus 1 (SeIV-1)

Biological Activity of SeMNPV, AcMNPV, and Three AcMNPV Deletion Mutants Against Spodoptera exigua Larvae (Lepidoptera: Noctuidae)

Journal of Invertebrate Pathology, 2000
Virulence and speed of action, as related to dose, are important effectiveness-determining properties of insect-pathogenic biocontrol agents. We used the droplet-feeding bioassay to compare dose responses between two wild-type baculoviruses, Autographa ...

The Influence of Greenhouse Chrysanthemum on the Interaction Between the Beet Armyworm, Spodoptera exigua, and the Baculovirus SeMNPV: Parameter Quantification for a Process-Based Simulation Model

Journal of Applied Entomology, 2001
During the building of a process-based simulation model for the epidemiology of the multicapsid nucleopolyhedrovirus of S. exigua (SeMNPV) in populations of Spodoptera exigua (Hübner) in greenhouse chrysanthemum, it was found that the effect of host ...
