Lethality of Chilo iridescent virus to Colladonus montanus leafhoppers

Identification of the Gene Encoding the Major Capsid Protein of Insect Iridescent Virus Type 6 by Polymerase Chain Reaction

“…The most important aspect which merits attention and support for research in this area is the biological relevance of iridoviruses. CIV is of agricultural importance, since it has been shown to infect the green rice leafhopper Nephtotettix eincticeps and to be 99 % lethal for the leafhopper Colladonus montanus (Homoptera: Cicadellidae), the vector of a mycoplasma agent of stone fruits (Jensen et al, 1972). The goal of the present study was the identification of the gene encoding the major capsid protein of CIV by PCR using oligonucleotide primers corresponding to the common structural feature of the major capsid proteins of TIV (Tajbakhsh et aI., 1990) and IV22 (Cameron, 1990).…”

Replication of Insect Iridescent Virus 6 in a Whitefly Cell Line

“…One candidate viral pathogen of whiteflies is the Insect iridescent virus 6 (IIV-6), also known as the Chilo iridescent virus. This virus was originally isolated from the rice stem borer (Chilo suppressalis) (Lepidoptera) (Fukaya and Nasu, 1966), but it was previously demonstrated that the virus can replicate in leafhoppers, leafhopper cells, and planthopper tissue explants (Jensen et al, 1972;Mitsuhashi, 1967). The ability to replicate in leafhopper cells raised the possibility that a whitefly cell line could also support IIV-6 replication.…”

Characterization of the Genome of Insect Iridescent Virus Type 6 by Physical Mapping

“…CIV was isolated by Fukaya & Nasu (1966) from Chilo suppressalis. CIV occurs in Japan and the U.S.A. (Smith, 1976) and is of agricultural importance, since it has been shown to infect Nephtotettix cincticeps and to be lethal for Colladonus montanus (Homoptera: Cicadellidae), which is the vector for transmission of a mycoplasma of stone fruits (Jensen et al, 1972). From this point of view CIV can be utilized in agriculture and considered as a biological insecticide, e.g.…”
