A rapid bioassay screen for quantifying nucleopolyhedroviruses (Baculoviridae) in the environment
Journal of Virological Methods, 1999A quantitative bioassay method for the detection of Helicoverpa armigera (Lepidoptera: Noctuidae) singly encapsulated nucleopolyhedroviruses (HaSNPVs) in soil is described. Calibration curves used for estimating soil virus titres in environmental samples were generated by incorporating a sterilised soil into a semi-synthetic insect diet then ...

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

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 ...

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.

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

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 ...

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.

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 ...

Transovarial transmission of Lymantria dispar Nucleopolyhedrovirus is shown with the RAPD-PCR method. Genetic markers of virus DNA found with the primer OPA-08 are recommended for diagnostics of Lymantria dispar nucleopolyhedrosis, in particular at the egg stage.
