Abstract

The iridovirus isolate termed cricket iridovirus (CrIV) was isolated in 1996 from L. and L. (both Orthoptera, Gryllidae). CrIV DNA shows distinct DNA restriction patterns different from those known for (IIV-6). This observation led to the assumption that CrIV might be a new species within the family CrIV can be transmitted perorally to orthopteran species, resulting in specific, fatal diseases. These species include L. and the African migratory locust (Orthoptera, Acrididae). Analysis of genomic and host range properties of this isolate was carried out in comparison to those known for IIV-6. Host range studies of CrIV and IIV-6 revealed no differences in the peroral susceptibility in all insect species and developmental stages tested to date. Different gene loci of the IIV-6 genome were analyzed, including the major capsid protein (274L), thymidylate synthase (225R), an exonuclease (012L), DNA polymerase (037L), ATPase (075L), DNA ligase (205R) and the open reading frame 339L, which is homologous to the immediate-early protein ICP-46 of frog virus 3. The average identity of the selected viral genes and their gene products was found to be 95·98 and 95·18% at the nucleotide and amino acid level, respectively. These data led to the conclusion that CrIV and IIV-6 are not different species within the family and that CrIV must be considered to be a variant and/or a novel strain of IIV-6.
