Efficacy of microencapsulated nucleopolyhedroviruses from Colombia as biological insecticides against Spodoptera frugiperda (Lepidoptera: Noctuidae)

Acta Agronómica, 2017
Wettable powder formulations by microencapsulation of viral occlusion bodies (OBs) of both Spodoptera frugiperda multiple nucleopolyhedrovirus from Colombia (SfCOL) and a genotypic variant (SfCOL-A) were evaluated for controlling the fall armyworm S ...

The History of Baculovirology in Africa [PDF]

Viruses, 2023
Baculovirology has been studied on the African continent for the development of insect virus-based biopesticides and, to a much lesser extent, vaccine production and delivery, since the 1960s.

Genome characteristics and the ODV proteome of a second distinct alphabaculovirus from Spodoptera litura [PDF]

BMC Genomics
Background Spodoptera litura is a harmful pest that feeds on more than 80 species of plants, and can be infected and killed by Spodoptera litura nucleopolyhedrovirus (SpltNPV).

Biosafety of Recombinant and Wild Type Nucleopolyhedroviruses as Bioinsecticides [PDF]

International Journal of Environmental Research and Public Health, 2007
The entomopathogenic Autographa californica (Speyer) nucleopolyhedrovirus (AcMNPV) has been genetically modified to increase its speed of kill. The potential adverse effects of a recombinant AcMNPV (AcAaIT) as well as wild type AcMNPV and wild type Spodoptera littoralis NPV (SlNPV) were studied.

Rapid Detection of Multiple Nucleopolyhedroviruses Using Polymerase Chain Reaction

Molecules and Cells, 2001
A technique using the polymerase chain reaction (PCR) was developed for detection of the nucleopolyhedrovirus (NPV) polyhedrin gene. The amino acid sequences of the polyhedrin gene were compared in twenty-six NPVs. A highly conserved DNA sequence within the coding region of the polyhedrin gene was targeted for amplification.

Interactions Between Nucleopolyhedroviruses and Polydnaviruses in Larval Lepidoptera

, 2012
The field dynamics of some insect populations are strongly influenced by two types of insect viruses: the nucleopolyhedroviruses (NPVs) and the polydnaviruses (PDVs). Although greatly different in origin and mode of infection, both viruses produce considerable mortality directly and indirectly in the field, and have evolved reproductive strategies that

Diversity and biological activity of nucleopolyhedroviruses of the leafworm Spodoptera litura

, 2018
Increased resistance of emerging cotton leafworm Spodoptera litura in Pakistan and elsewhere to chemical insecticides calls for an alternative method of control. Isolates of nucleopolyhedrovirus (NPVs) of S. litura (SpltNPV) were collected from infected larvae in different ecological and geographic regions of Pakistan.

Recombinant and Wild-Type Nucleopolyhedroviruses are Equally Fit in Mixed Infections [PDF]

Environmental Entomology, 2001
Abstract The recombinant nucleopolyhedrovirus of Autographa californica Speyer (AcMNPV-AaIT) expressing the paralyzing toxin of scorpions (Androtoctonus australis Hector) kills caterpillars 30% faster than wild-type (wt) AcMNPV, and shows a great deal of promise as a bioinsecticide.

Insect‐specific viruses used in biocontrol of mosquito‐borne diseases

Interdisciplinary Medicine, Volume 1, Issue 1, January 2023., 2023
Insect‐specific RNA viruses (ISRVs) are involved in a wide range of families including Flaviviridae, Bunyaviridae, Negeviruses, Togaviridae, Reoviridae, Mesoniviridae, and Rhabdoviridae, which cannot infect vertebrates, including humans. However, ISRVs can infect and replicate in mosquitoes, interfering with the replication of mosquito‐borne viruses ...

The distribution of covert microbial natural enemies of a globally invasive crop pest, fall armyworm, in Africa: Enemy release and spillover events

Journal of Animal Ecology, Volume 91, Issue 9, Page 1826-1841, September 2022., 2022
The infection of the invasive fall armyworm, with a natural enemy from its native range and novel pathogens from its new range, has important consequences for understanding the population ecology of invasive species and virus–insect interactions. The authors show that temporal and geographic factors are also important in understanding the distribution ...
