Comparative study on the susceptibility of cutworms (Lepidoptera: Noctuidae) to Agrotis segetum nucleopolyhedrovirus and Agrotis ipsilon nucleopolyhedrovirus

Journal of Invertebrate Pathology, 2003
The common cutworm (Agrotis segetum) and the black cutworm (Agrotis ipsilon) are serious soil pests of many vegetable and field crops all over the world. We have demonstrated the cross-infectivity of two baculoviruses, A. segetum nucleopolyhedrovirus (AgseNPV) and A. ipsilon nucleopolyhedrovirus (AgipNPV) for these two insect pests.

NUCLEOPOLYHEDROVIRUS PATHOLOGY IN SPRUCE BUDWORM LARVAE

The Canadian Entomologist, 2000
AbstractChoristoneura fumiferana (Clemens) (Lepidoptera: Tortricidae) multiple nucleopolyhedrovirus (CfMNPV) expressing green fluorescent protein was used to study aspects of nucleopolyhedrovirus infection in the spruce budworm. The temporal and spatial distribution of fluorescence indicated that the virus infected the midgut, entered the tracheal ...

Characterization of four isolates of Bombyx mori nucleopolyhedrovirus

Archives of Virology, 2000
Bombyx mori nucleopolyhedroviruses (BmNPVs), isolated from a sericultural Korean farm, were purified and characterized by their DNA restriction pattern, virus replication, polyhedra production and gene structures. The EcoR I and Sal I fragments showed similar overall patterns with minor difference but distinguishable patterns in each isolate. There was

Molecular characterization of Agrotis segetum nucleopolyhedrovirus from Poland

Journal of Invertebrate Pathology, 2005
The turnip moth, Agrotis segetum (Lepidoptera, Noctuidae), is an important pest insect in Europe, Asia, and Africa. We have genetically characterized and classified a nucleopolyhedrovirus isolated from A. segetum larvae in Poland (AgseNPV-P). The restriction pattern of AgseNPV-P was distinct from an isolate from England/France (AgseNPV-UK and AgseNPV-F)

Nucleopolyhedrovirus Interactions with Their Insect Hosts

1997
It is clear from this brief review that our understanding of the molecular cross-talk between insects and their baculovirus pathogens is still very limited. Studies in cell culture have taught us a great deal about the basic baculovirus molecular machinery and how it is regulated, and in many cases this information has been predictive of what occurs in

Characterization of Bombyx mori nucleopolyhedrovirus Bm17

Journal of Basic Microbiology, 2012
Open reading frame17 (Bm17) of Bombyx mori nucleopolyhedrovirus is a highly conserved gene in lepidopteran nucleopolyhedroviruses, suggesting that it performs an important role in the virus life cycle whose function is unknown. In this report, we describe the characterization of Bm17.

Phylogenetic analysis of Orgyia pseudotsugata single-nucleocapsid nucleopolyhedrovirus

Virologica Sinica, 2007
The Douglas-fir tussock moth Orgyia pseudotsugata (Lepidoptera: Lymantriidae) is a frequent defoliator of Douglas-fir and true firs in western USA and Canada. A single nucleopolyhedrovirus (SNPV) isolated from O. pseudotsugata larvae in Canada (OpSNPV) was previously analyzed via its polyhedrin gene, but is phylogenetic status was ambiguous.

Promoter analysis of Bombyx mori nucleopolyhedrovirus Ubiquitin gene

The Journal of Microbiology, 2008
The aim of this study was to analyze the characteristics of Bombyx mori nucleopolyhedrovirus (BmNPV) ubiquitin gene promoter and the effects of conserved motifs, such as TAAG, TATA, and CAAT, along with baculovirus enhancer homologous region 3 (hr3), on promoter activity.

Repeated Reversion of Resistance to Nucleopolyhedrovirus byAnticarsia gemmatalis

Journal of Invertebrate Pathology, 1998
A laboratory population of Anticarsia gemmatalis subjected to 80% mortality by the A. gemmatalis nucleopolyhedrovirus (AgNPV) developed a 5x resistance ratio (RR) within four generations. When exposure to AgNPV was discontinued, the resistant insects returned to their original level of susceptibility within three generations.
