To investigate the mechanism of nucleopolyhedrovirus resistance of silkworm, we bred a near-isogenic silkworm line, designated BC9, from the parental resistant strain NB and the susceptible strain 306, that is resistant to infection by nucleopolyhedrovirus. Proteomic techniques were employed to search for candidate genes playing a role in the antivirus response, based on differential protein ex...

The Lymantria dispar nucleopolyhedrovirus (LdMNPV) gene encoding the 25K FP protein has been cloned and sequenced. The 25K FP gene codes for a 217 amino acid protein with a predicted molecular mass of 24870 Da. Expression of the 25K FP protein in a rabbit reticulocyte system generated a 27 kDa protein, in close agreement with the molecular mass predicted from the nucleotide sequence. The gene i...

The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae) nucleopolyhedrovirus LdMNPV was tested as a synergist for nucleopolyhedroviruses against Helicoverpa zea (Boddie), Spodoptera exigua (Hübner), and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) larvae. The addition of the gypsy moth NPV significantly decreased the LC50s of AcMNPV, AfMNPV, GmMNPV, HaMNPV, HzSNPV, PxMN...

UNLABELLED Superinfection exclusion is the ability of an established virus to interfere with a second virus infection. This effect was studied in vitro during lepidopteran-specific nucleopolyhedrovirus (genus Alphabaculovirus, family Baculoviridae) infection. Homologous interference was detected in Sf9 cells sequentially infected with two genotypes of Autographa californica multiple nucleopolyh...

We report here the complete genomic sequence of Polish alphabaculovirus isolated from dead gypsy moth caterpillars. Its genome structure and G+C content indicate that it is a Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV) strain which possesses the shortest sequence among eight other (similar to reference sequence AF081810) LdMNPV sequences available in GenBank; it is 159,729 bp long.

A novel strain of Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV-27) was isolated from dead larvae of a Western Siberian (WS) population of gypsy moths (Lymantria dispar L.). We report the complete genome sequence of this strain, comprising 164,108 bp and double-stranded circular DNA encoding 162 predicted open reading frames.

The baculovirus, Chrysodeixis (formerly Pseudoplusia) includens nucleopolyhedrovirus (ChinNPV), is a new Alphabaculovirus pathogenic to Chrysodeixis includens Here, we report the complete genome sequences of six ChinNPV isolates. The availability of these genome sequences will provide information on ChinNPV molecular genetics, promoting understanding of its pathogenicity, diversity, and evolution.
