Biological Control, 1995
Abstract Laboratory experiments were conducted to determine the histopathological effects of pathogenic nonoccluded baculovirus (Mc-NOBV) in Microplitis croceipes (Cresson) (Hymenoptera: Braconidae), a potential parasitoid for the control of heliothine species of Lepidoptera. This virus is rod-shaped and has a single envelope.

Neotropical Entomology, 2022
A novel baculovirus observed to infect Automeris liberia (Cramer) (bullseye moth) is here described. Caterpillars of A. liberia with symptoms of viral infection were collected from African oil palm plantations in Tailândia, PA, Brazil. Macerated caterpillars were then offered to caterpillars of Automeris cinctistriga (Felder & Rogenhoper), leading to ...

Environmental Entomology, 1995
Four combinations of healthy (H) and infected with nonoccluded Microplitis croceipes baculovirus (I) adult Microplitis croceipes (Cresson) were paired and mated as follows: group I, I♂ + I,♀; group II,H♂+ I♀ ; and group III, 1♂ + H♀; and group IV (control), H♂ + H♀. Females were allowed to parasitize 3rd instars of tobacco budworms, Heliothis virescens

Environmental Entomology, 1996
Transmission of Microplitis croceipes (Cresson) nonoccluded baculovirus (Mc-NOBV) within and among individual Microplitis croceipes wasps was studied by light microscopy and transmission electron microscopy. Systemic transmission by way of hemolymph may represent the major route of transmission of this virus in a host.

Activity persistence of granulosis viruses [Baculoviridae] in soils in United Kingdom and Denmark
Entomophaga, 1988The persistence of granulosis virus infectivity in soil has been investigated. Virus applied to soil was extracted at different times up to 1 year after the original application and the amount of virus was determined using bioassays. In this way the content of infective capsules remained was determined. It was shown that about 99% of the original virus

Journal of Virological Methods, 2001
A diagnostic method is described for the identification and differentiation of nucleopolyhedrovirus (NPV) pathogens of Helicoverpa species (Lepidoptera: Noctuidae) isolated from the environment. The method is based on the polymerase chain reaction (PCR) used in conjunction with restriction fragment length polymorphism (RFLP) analysis and comprises ...

Publisher Summary Baculoviruses are complex viruses that cause diseases in invertebrates, notably insects. The virus particles are enveloped rod-shaped entities. The envelope surrounds a nucleocapsid containing a deoxyribonucleoprotein complex. In the case of nuclear polyhedrosis virus (NPV) or granulosis virus (GV) the virus, particles may be ...

The Spodoptera exigua (Hübner) multiple nucleopolyhedrovirus (SeMNPV) is currently being tested as a biological insecticide for use in greenhouse crops in southern Spain. We performed a study in which semipurified SeMNPV occlusion bodies (OBs) were formulated in phosphate-buffered saline, pH 6.5, with 5% (vol:vol) glycerol and 0.15% (wt:vol) sorbic ...

Entomophaga, 1982
No consistent deleterious effects directly attributable to the nuclear polyhedrosis virus ofMamestra brassicae (L.),Autographa californica (Speyer) and the granulosis virus ofLaspeyresia pomonella (L.) were observed, when bone marrow cells of Chinese hamsters and NMRI mice were examined for chromosomal aberrations or sister chromatic exchanges.
