Summary:Bombyx mori densovirus belongs to Parvoviridae. It is classified into 2 species. Some silkworm strains show absolute resistance (nonsusceptibility) against either or both viruses. Crosses between resistant and susceptible silkworms revealed the existence of 3 resistance genes. So far we have isolated 2 of these genes by positional cloning. We isolated the homologous genes of B.mandarina which is a probable wild species of B.mori. The genotypes of resistance or susceptibility to the densoviruses coincided with responses to viral inoculation. We will discuss the relationship among the viruses, B mori and B.mandarina from the results of genotyping using these resistance genes.
