The genus Diadegma is a well known parasitoid group in various lepidopteran insect such as Plutella xylostella andsome are known to have symbiotic virus. Previously we reported a novel ichnovirus as named Diadegma fenestrale Ichnovirus(DfIV, 62 segments, 247,238bp) from D. fenestrale which parasitized in the P. xylostella. Here we report another ichnovirus,DsIV from Taiwan strain of D. semiclausum which parasitized in the P. xylostella. Total 64 genomic segments were sequenced,185,053bp from DsIV. Two Ichnovirus showed high similarity in 99 regions in most of segments. We already confirmedintegration of DfIV genome segments into the chromosome from the P. xylostella via genome sequencing of the lepidopteranhost. Therefore some of recombination could be passible inside of the lepidopteran genome.
