1. Infectividade in vitro de Spodoptera frugiperda multiple nucleopolyhedrovirus a diferentes linhagens celulares de insetos
Resumo: O objetivo deste trabalho foi avaliar uma gama de hospedeiros, in vitro, quanto à resposta a Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), um vírus patogênico à lagarta-do-cartucho (Spodoptera frugiperda; Lepidoptera: Noctuidae), para o posterior desenvolvimento de um biopesticida baseado em sistema de cultura de células.

2. Sequencing and de novo assembly of the Asian gypsy moth transcriptome using the Illumina platform
Abstract The Asian gypsy moth (Lymantria dispar) is a serious pest of forest and shade trees in many Asian and some European countries. However, there have been few studies of L. dispar genetic information and comprehensive genetic analyses of this species are needed in order to understand its genetic and metabolic sensitivities, such as the molting mechanis

4. Host Range Factor 1 from Lymantria dispar Nucleopolyhedrovirus (NPV) Is an Essential Viral Factor Required for Productive Infection of NPVs in IPLB-Ld652Y Cells Derived from L. dispar
Host range factor 1 (HRF-1) of Lymantria dispar multinucleocapsid nucleopolyhedrovirus promotes Autographa californica MNPV replication in nonpermissive Ld652Y cells derived from L. dispar. Here we demonstrate that restricted Hyphantria cunea NPV replication in Ld652Y cells was not due to apoptosis but was likely due to global protein synthesis arrest that c

5. Comparative Replication of Lymantria dispar Nuclear Polyhedrosis Virus Strains in Three Continuous-Culture Cell Lines
We compared the replication of the gypsy moth (Lymantria dispar) nuclear polyhedrosis virus in two new cell lines, from embryos and fat body of L. dispar, and in a previously available ovarian cell line. Three virus isolates (the Hamden strain [LDP-67] used commercially as GYPCHEK, a plaque-purified clone of Hamden [5-7d], and an isolate from Abington, Mass.

6. Synergistic effect of the Bacillus thuringiensis toxins CryIAa and CryIAc on the gypsy moth, Lymantria dispar.
The insecticidal activity of toxins CryIAa, CryIAb, and CryIAc against Lymantria dispar (gypsy moth) and Bombyx mori (silkworm) was examined by force-feeding bioassays. Toxin CryIAa exhibited higher toxicity than toxins CryIAb and CryIAc for L. dispar and B. mori. To evaluate possible synergism among these toxins, bioassays were performed with mixtures of Cr

7. Effect of Bacillus thuringiensis Cry1 Toxins in Insect Hemolymph and Their Neurotoxicity in Brain Cells of Lymantria dispar
Little information is available on the systemic effects of Bacillus thuringiensis toxins in the hemocoel of insects. In order to test whether B. thuringiensis-activated toxins elicit a toxic response in the hemocoel, we measured the effect of intrahemocoelic injections of several Cry1 toxins on the food intake, growth, and survival of Lymantria dispar (Lepid

8. Lymantria dispar Nucleopolyhedrovirus hrf-1 Expands the Larval Host Range of Autographa californica Nucleopolyhedrovirus
The gypsy moth (Lymantria dispar) is nonpermissive for Autographa californica nucleopolyhedrovirus (AcNPV) infection. We previously isolated a gene, host range factor 1 (hrf-1), from L. dispar nucleopolyhedrovirus that promotes AcNPV replication in Ld652Y cells, a nonpermissive L. dispar cell line (S. M. Thiem, X. Du, M. E. Quentin, and M. M. Berner, J. Viro

9. Discovery of Entomophaga maimaiga in North American gypsy moth, Lymantria dispar.
An entomopathogenic fungus, Entomophaga maimaiga, was found causing an extensive epizootic in outbreak populations of the gypsy moth, Lymantria dispar, throughout many forested and residential areas of the northeastern United States. This is the first recognized occurrence of this or any entomophthoralean fungus in North American gypsy moths, and its appeara

10. Protein Synthesis in a Lymantria dispar Cell Line Infected by Cytoplasmic Polyhedrosis Virus
The efficiency of replication of a cytoplasmic polyhedrosis virus isolated from a member of the order Lepidoptera, Euxoa scandens, was studied in eight different lepidopterean cell lines. Lymantria dispar cells, which were found to support viral replication, more efficiently, were used to follow the kinetics of appearance of viral-specific polypeptides by a

11. Molecular analysis of an enhancin gene in the Lymantria dispar nuclear polyhedrosis virus.
A Lymantria dispar nuclear polyhedrosis virus (LdMNPV) gene has been identified that encodes a homolog to the granulovirus (GV) enhancin proteins that are capable of enhancing the infection of other baculoviruses. Enhancin genes have been identified and sequenced for three species of GVs but have not been found in any other nuclear polyhedrosis virus to date

12. New cell lines from Ephestia kuehniella: characterization and susceptibility to baculoviruses
New cell lines from embryos of Ephestia kuehniella were recently developed. Primary cultures were initiated in September 2002 from 2 to 4 day old eggs in either modified TC-100 or ExCell 400 medium. From these initial cultures, one, originally isolated in the Ex-Cell medium, produced sufficient cell growth to allow subcultivation and eventually led to the es
