The genus Diadegma is a well known parasitoid group and some are known to have symbiotic virus, PDV. A novel IV was discovered from the calyx of D. fenestrale female. This virus was named as D. fenestrale Ichnovirus (DfIV). The encapsidated DfIV genome contains 65 circular DNA segments with an aggregate size of 247,191 bp. Based on BLAST analysis, a total of 120 ORFs were predicted as follows: rep; 48, cys-motif; 11, vinnexin; 10, vankyrin; 9, PRRP; 3 and other unassigned genes (39). These viral genes were expressed in lepidopteran hosts (Phthorimaea operculella and Plutella xylostella) after parasitization which means DfIV genome segments were integrated into lepidopteran hosts. This study was focused on this result. Based on gene expression profile, candidate promoter and integration motifs were selected and then, fused with eGFP as a reporter gene. Modified DfIV genome segment was ligated to a commercial containing f1 ori and Ampr gene to propagate in E. coli. We have named this fusion vector as pIN. The construction methodology of pIN and its application would be further discussed in detail.
