Baculovirus-induced climbing behavior favors intraspecific necrophagy and efficient disease transmission in Spodoptera exigua
Shortly prior to death, many species of Lepidoptera infected with nucleopolyhedrovirus climb upwards on the host plant. This results in improved dissemination of viral occlusion bodies over plant foliage and an increased ... -
Co-infection with iflaviruses influences the insecticidal properties of Spodoptera exigua multiple nucleopolyhedrovirus occlusion bodies: implications for the production and biosecurity of baculovirus insecticides
Biological insecticides based on Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) can efficiently control S. exigua larvae on field and greenhouse crops in many parts of the world. Spanish wild populations and ... -
Gender-mediated differences in vertical transmission of a nucleopolyhedrovirus
With the development of sensitive molecular techniques for detection of low levels of asymptomatic pathogens, it becoming clear that vertical transmission is a common feature of some insect pathogenic viruses, and likely ... -
Iflavirus covert infection increases susceptibility to nucleopolyhedrovirus disease in Spodoptera exigua
Naturally occurring covert infections in lepidopteran populations can involve multiple viruses with potentially different transmission strategies. In this study, we characterized covert infection by two RNA viruses, ... -
Iflavirus increases its infectivity and physical stability in association with baculovirus
Virus transmission and the prevalence of infection depend on multiple factors, including the interaction with other viral pathogens infecting the same host. In this study, active replication of an iflavirus, Spodoptera ... -
Interference of iflavirus in SeMNPV as a biological control agent
La rosquilla verde, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), es una especie polífaga ampliamente distribuida por todas las zonas templadas del mundo, incluyendo España, donde se ya ha establecido, causando ... -
Intra- and intergenerational persistence of an insect nucleopolyhedrovirus: adverse effects of sublethal disease on host development, reproduction, and susceptibility to superinfection
Sublethal infections by Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) are common in field populations of the beet armyworm (S. exigua, Hübner) in the Almerian horticultural region of Spain. Inoculation of ... -
Post-mortem incubation influences occlusion body production in nucleopolyhedrovirus-infected larvae of Spodoptera frugiperda
The inefficient production of nucleopolyhedrovirus occlusion bodies (OBs) can limit the commercialization of virus-based insecticides. The production of OBs in SfMNPV-infected Spodoptera frugiperda fourth instars was ... -
Vertical transmission of the Spodoptera exigua multiple nucleopolyhedrovirus and its application in biological control
Las infestaciones de larvas de Spodoptera exigua (Lepidoptera: Noctuidae) son muy frecuentes en los cultivos de pimiento de los invernaderos de Almería. En estudios previos, la caracterización molecular e identificación ...
