13. Seleção genetica do virus de poliedrose nuclear de Autographa Californica (Baculoviridae) em diatraca saccharalis (Fabr., 1974) (Lepidoptera pyralidae)
The genetic variant E2 from the Autographa californica Nuclear Polyedrosis Virus (AcNPV) was serially passed for five generations in its alternate host Oiatraea saccharalis the sugarcane borer. From these passages four isolates were obtained besides the original inoculum (IV-I, IV-2, IV-3, IV-4 and E2). These isolates were compared to each other considering

15. Rifampin inhibition of the occluded virus form of a nuclear polyhedrosis virus.
Rifampin at concentrations toxic to noninfected cells but not to infected cells is a selective inhibitor of occluded virus of the group A Baculoviridae (nuclear polyhedrosis virus). However, the titer of nonoccluded virus is not affected. Rifampin blocks occlusion until late in the replication cycle (14 to 16 h), and its effects are reversible. Modes of acti

16. Identification of the Lymantria dispar Nucleopolyhedrovirus Envelope Fusion Protein Provides Evidence for a Phylogenetic Division of the Baculoviridae†
The complete genome sequences of a number of diverse members of the Baculoviridae including both nucleopolyhedroviruses (NPVs) and granuloviruses (GVs) revealed that they lack a homolog of GP64, the envelope fusion protein of the budded form of Autographa californica multinucleocapsid NPV (AcMNPV) and its close relatives. Computer-assisted analyses of the ge

17. Analysis of the Complete Genome Sequence of the Hz-1 Virus Suggests that It Is Related to Members of the Baculoviridae
We report the complete sequence of a large rod-shaped DNA virus, called the Hz-1 virus. This virus persistently infects the Heliothis zea cell lines. The Hz-1 virus has a double-stranded circular DNA genome of 228,089 bp encoding 154 open reading frames (ORFs) and also expresses a persistence-associated transcript 1, PAT1. The G+C content of the Hz-1 virus g

18. Ancient Coevolution of Baculoviruses and Their Insect Hosts
If the relationships between baculoviruses and their insect hosts are subject to coevolution, this should lead to long-term evolutionary effects such as the specialization of these pathogens for their hosts. To test this hypothesis, a phylogeny of the Baculoviridae, including 39 viruses from hosts of the orders Lepidoptera, Diptera, and Hymenoptera, was reco

19. Determination of the protein composition of the occlusion-derived virus of Autographa californica nucleopolyhedrovirus
The occlusion derived form of baculovirus is specially adapted for primary infection of the host midgut epithelium. As such, the virion must contain the proteins essential for host range determination and initiation of infection. Because knowledge of virion composition is a prerequisite for functional investigation, this study used a combination of techn

20. Baculovirus Stimulates Antiviral Effects in Mammalian Cells
Herein, we report that Autographa californica nucleopolyhedrovirus, a member of the Baculoviridae family, is capable of stimulating antiviral activity in mammalian cells. Baculoviruses are not pathogenic to mammalian cells. Nevertheless, live baculovirus is shown here to induce interferons (IFN) from murine and human cell lines and induces in vivo protection

21. Risk Assessment Studies: Detailed Host Range Testing of Wild-Type Cabbage Moth, Mamestra brassicae (Lepidoptera: Noctuidae), Nuclear Polyhedrosis Virus
The host range of a multiply enveloped nuclear polyhedrosis virus (NPV) (Baculoviridae) isolated from the cabbage moth, Mamestra brassicae (Lepidoptera: Noctuidae), was determined by challenging a wide range of insect species with high (106 polyhedral inclusion bodies) and low (103 polyhedral inclusion bodies) doses of the virus. The identity of the progeny

22. Host range expansion by recombination of the baculoviruses Bombyx mori nuclear polyhedrosis virus and Autographa californica nuclear polyhedrosis virus.
The mechanisms of host specificity of nuclear polyhedrosis viruses (NPVs) (Baculoviridae) were analyzed after coinfection of Bombyx mori NPV (BmNPV) and one of four distinct groups of Spodoptera litura NPV (SlNPV), including an Autographa californica NPV (AcNPV) variant (S. Maeda, Y. Mukohara, and A. Kondo, J. Gen. Virol. 71:2631-2639, 1990), into various le

23. Multiple Nucleocapsid Packaging of Autographa californica Nucleopolyhedrovirus Accelerates the Onset of Systemic Infection in Trichoplusia ni
Among the nucleopolyhedroviruses (Baculoviridae), the occlusion-derived virus (ODV), which initiates infection in host insects, may contain only a single nucleocapsid per virion (the SNPVs) or one to many nucleocapsids per virion (the MNPVs), but the significance of this difference is unclear. To gain insight into the biological relevance of these different

24. Early Synthesis of Budded Virus Envelope Fusion Protein GP64 Enhances Autographa californica Multicapsid Nucleopolyhedrovirus Virulence in Orally Infected Heliothis virescens
Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV), the type species of the Nucleopolyhedrovirus genus (Baculoviridae family), has two highly unusual traits shared by several baculovirus species. First, the occlusion-derived virus (ODV) that establishes primary infection in the midgut following its ingestion by host larvae contains multiple nuc
