Field Application of SeMNPV (Spodoptera exigua Multiple Nucleopolyhedrovirus) for Controlling Spodoptera exigua on Shallot and Scallion in the Mekong Delta, Vietnam

Research in Ecology
Shallot and scallion are among the essential horticultural crops in the Mekong Delta of Vietnam, and their yields and quality are affected by the beet armyworm, Spodoptera exigua. To control this pest, farmers have used a large number of insecticides, which has led to resistance due to continuous use and environmental harm, thereby increasing interest ...

A New Cell Line (NTU-SE) From Pupal Tissues of the Beet Armyworm, Spodoptera exigua (Lepidoptera: Noctuidae), Is Highly Susceptible to S. Exigua Multiple Nucleopolyhedrovirus (SeMNPV) and Autographa californica MNPV (AcMNPV)

Journal of Invertebrate Pathology, 2012
A new continuous cell line, NTU-SE, was established from the pupal tissues of an economically important pest, the beet armyworm Spodoptera exigua (Lepidoptera: Noctuidae). This cell line contains four major morphologic types: round, polymorphic, spindle-shaped, and comma-shaped cells.

Production of SeNPV in a Suspension of an Established Spodoptera Exigua Cell Line

1995
Baculoviruses are potential biological control agents. Traditionally, baculoviruses are produced in insect larvae, which is a laborious process and difficult to scale-up. Modern cell-culture technology facilitates the growth of insect cells in suspension in bioreactors.

SeMNPV reactivation through stress factors in covertly infected Spodoptera exigua

2013
Spontaneous reactivation of baculovirus has been postulated as the main cause to explain outbreaks in laboratory insect cultures that have never been exposed to virus and in the development of epizootics in natural populations. Recent studies have reported a high prevalence of baculovirus covert infections in lepidopteran populations, such as ...

Comparative effects of "defective" genotypes in NPV populations: their roles in SfMNPV vs SeMNPV

2016
The Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) isolate from Florida, US (SeUS2) is a complex mixture of genotypes. The genotypic structure of this isolate is very similar to that of the S. frugiperda MNPV isolated from Nicaragua (SfNIC), which is composed of at least nine genotypes.

Bacterially produced dsRNA targeting SePGRP-LB reduces population fitness of Spodoptera exigua (Lepidoptera: Noctuidae) and increases its susceptibility to SeMNPV

Journal of Economic Entomology
Abstract The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is an important agricultural pest, and S. exigua multiple nucleopolyhedrovirus (SeMNPV) is a host-specific biological control agent. However, baculovirus efficacy can be limited by host antiviral responses. S.
