“…In a previous work describing the ultrastructure and pathogenesis of a baculovirus isolated from larvae of Dione juno juno (Lepidoptera: Nymphalidae), Ribeiro et al [13] found that Dione juno nucleopolyhedrovirus (DijuNPV) was able to effectively kill caterpillars from the species D. juno and Agraulis vanilae (Lepidoptera: Nymphalidae), as confirmed by Rodrigues et al [14]. D. juno is the most recurrent pest of passionfruit crops in Brazil and other tropical countries, and it eventually causes high damage to crop due to its gregarious habits [15].…”

“…DijuNPV is highly pathogenic to nymphalid caterpillars of both species D. juno and A. vanilla and could be potentially used for passionfruit crop protection [13,14]. The isolate of DijuNPV was previously characterized at ultrastructural, biological [13], and molecular [14] levels, though it was never characterized at a wide genomic approach. In this work, we sequenced and characterized the genome of DijuNPV by two deep sequencing complementary techniques (i.e., 454 and Illumina).…”

Baculoviruses are capable of infecting a wide diversity of insect pests. In the 1990s, the Dione juno nucleopolyhedrovirus (DijuNPV) was isolated from larvae of the major passionfruit defoliator pest Dione juno juno (Nymphalidae) and described at ultrastructural and pathological levels. In this study, the complete genome sequence of DijuNPV was determined and analyzed. The circular genome presents 122,075 bp with a G + C content of 50.9%. DijuNPV is the first alphabaculovirus completely sequenced that was isolated from a nymphalid host and may represent a divergent species. It appeared closely related to Orgyia pseudotsugata multiple nucleopolyhedrovirus (OpMNPV) and other Choristoneura-isolated group I alphabaculoviruses. We annotated 153 open reading frames (ORFs), including a set of 38 core genes, 26 ORFs identified as present in lepidopteran baculoviruses, 17 ORFs unique in baculovirus, and several auxiliary genes (e.g., bro, cathepsin, chitinase, iap-1, iap-2, and thymidylate kinase). The thymidylate kinase (tmk) gene was present fused to a dUTPase (dut) gene in other baculovirus genomes. DijuNPV likely lost the dut portion together with the iap-3 homolog. Overall, the genome sequencing of novel alphabaculoviruses enables a wide understanding of baculovirus evolution.

“…It could be the case that warmer and wetter winters negatively impact Passiflora , although another and perhaps more likely explanation is that wetter and warmer winters increase parasitoid pressure and/or disease leading to reduced adult emergence the next year (Harvell et al ., ; Stireman III et al ., ). Agraulis vanillae is known to host nucleopolyhedrovirus (Rodriguez et al ., ), which could be one mechanism that generated the observed negative density dependence (see Supporting information, Fig. S4); however, this is not known to impact California populations.…”

1. The changing climate is altering species distributions with consequences for population dynamics, resulting in winners and losers in the Anthropocene.2. Agraulis vanillae, the gulf fritillary butterfly, has expanded its range in the past 100 years in the western U.S.A. Time series analysis is combined with species distribution modelling to investigate factors limiting the distribution of A. vanillae and to predict future shifts under warming scenarios.3. Time series analyses from the western U.S.A. show that urban development has a positive association with year of colonisation (the host plant Passiflora is an ornamental in gardens). Colonisation was also associated positively and to a lesser extent with winter maximum temperatures, whereas a negative impact of minimum temperatures and precipitation was apparent on population growth rates after establishment.4. Species distribution models vary by region. In the eastern U.S.A., the butterfly is primarily limited by minimum temperatures in the winter and host availability later in the season. Eastern U.S. projected expansion broadly follows the expectation of poleward distributional shifts, especially for the butterfly's maximum annual extent. Western U.S. distributions are limited by the host plant, which in turn is dependent on urban centres. Projected western U.S. expansion is not limited to a single direction and is driven by urban centres becoming more suitable for the host plant.5. These results demonstrate the value of combining time series with spatial modelling, at the same time as incorporating biotic interactions, aiming to understand and predict shifting geographical ranges in the Anthropocene.

“…Since the beginning of studies on the baculovirus genomes, many researchers have designed PCR tests to detect, identify and classify the different species of this virus Family. Thus, PCR assays based on polyhedrin/granulin, p74, lef8, lef9 or DNA polymerase genes, among others, were used to describe new virus isolates which are candidates to bioinsecticide applications (Faktor et al, 1996;de Moraes et al, 1999;Wang et al, 2000;Rosisnki et al, 2002;Espinel-Correal et al, 2011;Rodríguez et al, 2011). However, there are too many examples of the use of PCR as a technique for quality control in the production of a baculovirus, despite all the advantages mentioned above (Christian et al, 2001;Murillo et al, 2006).…”
