Virus entry or the primary infection cycle are not the principal determinants of host specificity of Spodoptera spp. nucleopolyhedroviruses

Journal of General Virology, 2004
The multicapsid nucleopolyhedroviruses (NPVs) of Spodoptera exigua (SeMNPV), Spodoptera frugiperda (SfMNPV), and Spodoptera littoralis (SpliNPV) are genetically similar (78 % similarity) but differ in their degree of host specificity. Infection by each of the three NPVs in these three Spodoptera host species was determined by oral inoculation of larvae

Comparative analysis of the complete genome sequences of Helicoverpa zea and Helicoverpa armigera single-nucleocapsid nucleopolyhedroviruses

Journal of General Virology, 2002
The complete nucleotide sequence of Helicoverpa zea single-nucleocapsid nucleopolyhedrovirus (HzSNPV) has been determined (130869 bp) and compared to the nucleotide sequence of Helicoverpa armigera (Ha) SNPV. These two genomes are very similar in their nucleotide (97% identity) and amino acid (99% identity) sequences.

Isolation and Characterization of a Nucleopolyhedrovirus from Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae) [PDF]

, 2012
Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae) is an important pest of vegetable crops widely distributed in South America. At present, its control is based on the use of broad spectrum chemical insecticides.

Synergism between the nucleopolyhedroviruses of Autographa californica and Trichoplusia ni.

Acta virologica, 2004
Previous observations on high virulence of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Trichoplusia ni single nucleopolyhedrovirus (TnSNPV) acting together led us to test possible synergism between these two nucleopolyhedroviruses (NPVs) on cabbage looper larvae.

Managing legume pests in sub-Saharan Africa: Challenges and prospects for improving food security and nutrition through agro-ecological intensification [PDF]

, 2013
Pest management technology has been through a number of advances that have, perhaps, moved away from the mass extermination of pests achieved through the advent of synthetic chemicals in the latter half of the 20th century to more agro-ecologically ...

Analysis of the genome of Spodoptera frugiperda nucleopolyhedrovirus (SfMNPV-19) and of the high genomic heterogeneity in group II nucleopolyhedroviruses

Journal of General Virology, 2008
The genome of the most virulent among 22 Brazilian geographical isolates of Spodoptera frugiperda nucleopolyhedrovirus, isolate 19 (SfMNPV-19), was completely sequenced and shown to comprise 132 565 bp and 141 open reading frames (ORFs). A total of 11 ORFs with no homology to genes in the GenBank database were found.
