Nucleopolyhedrovirus Coocclusion Technology: A New Concept in the Development of Biological Insecticides
A new approach to the development of NPV-based insecticides is described that takes advantage of the unique way in which these viruses are transmitted as collective infectious units, and the genotypic diversity present in natural virus populations, to produce highly pathogenic virus preparations for pest control.
Granuloviruses in Insect Pest Management
In order to increase the uptake of baculoviruses, it is necessary to develop robust molecular biology techniques, to enhance safe food production for the nutritional and health security of growing population.
Diversity and biological activity of nucleopolyhedroviruses of the leafworm Spodoptera litura
The results of this thesis considerably enhanced the understanding of the genetic and biological diversity of SpltNPVs in conjunction with their spatial distribution and the crop system involved and may be used to develop Splt NPV as an eco-rational control agent of the leafworm S. litura in Pakistan.
Genome-wide In Silico Analysis, Characterization and Identification of Microsatellites in Spodoptera littoralis Multiple nucleopolyhedrovirus (SpliMNPV)
The SSR markers specific to SpliMNPV, developed in this study, could be a useful tool for the identification of isolates and analysis of genetic diversity and viral evolutionary status.
Mulberry leaves treated with bordeaux mixture protect silkworm caterpillars against fungal and viral diseases
In the case of BmNPV, the 10% bordeaux mixture solution promoted greater resistance to viral infection, possibly favoring the activation of defense mechanisms of insects.


A review of safety tests on baculoviruses
Confidence suggests that new NPVs and GVs in these orders need be subjected only to a reduced range of the more challenging tests and to tests designed to reveal harm originating from the insect species used for virus production and from contaminants.
Bibliographie über biologische Bekämpfung
Im Rahmen der Arbeiten der Internat ionalen Organisation ffir Biologisehe Sehgdlingsbekgmpfung (O.I.L.B.) wird hier die zehnte Bibliographie ver6ffentlieht, die sieh mit Grundlagen und Anwendung
Comparaison de la composition génétique de trois isolats du baculovirus de la polyedrose nucléaire du lépidoptèreSpodoptera littoralis
Three Baculoviruses were isolated from Spodoptera littoralis larvae infected with nuclear polyhedrosis (NPV) collected from Morocco, Egypt, and a from laboratory culture at Lyon (France).
Cross-infectivity and activation studies with four baculoviruses
It seems clear that when independent identification techniques are used it can be demonstrated that infecting an insect larva with a NPV from another host can result in death due to infection with the NPV normally associated with that host rather than that used as inoculum.
Industrial and international standardization of microbial pesticides — II. Insect viruses
Nuclear polyhedrosis virus (Baculovirus) (NPV) preparations, designed for biological control of insects, have to be standardized by bioassay in nearly the same way asBacillus thuringiensis
Influence de passages répétés du virus de la polyèdrose nucléaire deAutographa californica chezSpodoptera littoralis [Lep.: Noctuidae]
It seems that NPV's are more stable than sometimes is suggested as far as natural routes of infection are used in the experimentation.
Recherches sur la spécificité de trois virus a polyèdres nucléaires vis-a-vis deMamestra brassicae, scotia segetum, trichoplusia ni etSpodoptera exigua
By surface spray on artificial food medium the comparative activity of three nuclear polyedrosis viruses, using formulations prepared in an identical way, has been studied on newly hatched larvae of four noctuid species to emphasize the importance in microbial control of quantitative approaches when studying host ranges in insect viruses.
Susceptibility of larvae ofHeliothis zea, H. virescens, andH. armigera [lep.: Noctuidae] to 3 baculoviruses
The pattern of virulence (based on inclusion bodies) for 3 baculoviruses ofHeliothis, i.e. a unicapsid, nuclear polyhedrosis virus (HzSNPV); a multicapsid; a multicapping virus; and a granulosis virus (HaGIV) was the same for 3 species of Helioth is.
Études histologiques et ultrastructurales des larves dePandemis heparana [Lep. Tortricidae] au cours des stades avancés d'une baculovirose due a un nouveau virus inducteur de diapause
Study by light and electron microscopy of L5 and L6 larvae exhibiting very marked symptoms of the virus disease (early stages of paralysis and whitish colour of abdominal segments) shows that the site of multiplication of theirus is mainly located in the fat body cells and occasionally in some hemocytes or hypoderm cells.
Évolution de la composition génétique et du pouvoir infectieux du Baculovirus deMamestra brassicae L. au cours de 25 multiplications successives sur les larves de la Noctuelle du Chou
The modification of the genome has no appreciable effect on the infectivity of successive viral preparations of Mamestra brassicae Baculovirus during 25 successive passages in 5th instar cabbage armyworm larvae infectedper os.
