Kanga, L. and Fediere, G., 1991. Towards integrated control of Epicerura pergrisea (Lepidoptera:Notodontidae), defoliator of Terminalia ivorensis and T. superba, in the Côte d'Ivoire. For. Ecol. Manage., 39: 73-79. The commercial plantations of Terminalia spp. in the Côte d'Ivoire are periodicalty defoliated by caterpillars of Epicerura pergrisea Hampson. The insect damage significantly decreases the yield of plantations. Two insecticides were tested with satisfactory results. Within 24 h of… 
Isolation of Densovirus and Picornavirus from natural field populations of Spodoptera littoralis Boisd. (Lep. Noctuidae) in Egypt
Results suggest that the DNV isolated from S. Iittoralis shows a complete serological identity with the DCV, and can be registrated as a strain of MDNV and the small RNA virus as an Egyptian strain of DCV.
Biological and Molecular Properties of Densoviruses and Their Use in Protein Expression and Biological Control
The first report of an insect disease caused by a densovirus (DNV) goes back to the early 1960s when the Laboratoire de Pathologie Comparee, a reference center for diagnosis of invertebrate pathogens
A new Densovirus isolated from the African cotton bollworm Helicoverpa armigera Hbn. (Lepidoptera: Noctuidae) in Egypt
The 6 kb genome of HaDNV was found to have high homology with members of the Densovirus genus as Galleria mellonella DNV, Junonia coenia DNVand MlDNV.
Multiplication of Sesamia cretica granulovirus in two homogeneous cell lines
A complete replication of the Sesamia cretica Granulovirus was obtained in vitro by viral irzfectiorz, as a first record, in two Spodoptera cell lines, S152 arid Sf 9.
the Helicoverpa armigera Densovirus Organization of the Ambisense Genome of
The cotton bollworm has become increasingly resistant to pes-ticides, necessitating biological or integrated pest manage-ment, and densoviruses (DNVs) have shown great potential, e.g.,complete control of the pest.
Organization of the Ambisense Genome of the Helicoverpa armigera Densovirus
A natural densovirus of a serious phytophagous pest, Helicoverpa armigera, was isolated and its DNA sequence and ambisense organization demonstrated that it belonged to the genus Densovirus in the subfamily Densovirinae of the family Parvoviridae.


Field Tests of a Nuclear Polyhedrosis Virus in a Bait Formulation for Control of Pink Bollworms and Heliothis Spp. in Cotton in Arizona
The effect of the bait alone on pink boll worms in cotton seemed to result in part from altered feeding behavior of 1st-instars; the newly-hatched larvae were observed feeding on cotton leaves when the bait was present.
Le densovirus de Casphalia extranea et ses potentialités en lutte biologique
Les larves du lepidoptere Casphalia extranea (Limacodidae) pullulent periodiquement sur les plantations de cocotier et de palmier a huile en Cote d'Ivoire. Un des facteurs de controle naturel de ces
Etude du Ribovirus de Latoia viridissima Holland, ravageur de palmacae en Afrique de l'Ouest: caractérisation, diagnostic sérologique, suivi épidémiologique
Une revue des entomopathogenes locaux regulant les populations naturelles de ce ravageur a precedemment montre that l'agent de controle le plus efficace etait un virus.
This new virus could be provisionally arranged among the unclassified small RNA vu~ses of invertebrales and represents a great interst as a biological control agent as well as serologically unrelated to certain inseci Picoma-like viruses.
Production and field evaluation of codling moth granulosis virus for control of Cydia pomonella in the United Kingdom.
The results indicate that codling moth GV is an effective control agent particularly in reducing numbers of larvae and the more severe forms of fruit damage.
Restriction enzyme analysis of granulosis viruses isolated from Artogeia rapae and Pieris brassicae
Thirteen isolates of granulosis virus from Artogeia (= Pieris) rapae and two from Pieris brassicae were compared by restriction enzyme analysis, suggesting that the isolates could be placed in three subtypes.
