The ecdysteroid UDP glucosyltransferase (EGT) gene of Spodoptera litura multinucleocapsid nuclear polyhedrosis virus ( Sl MNPV)
which located within a Pst Ⅰ 4 970 bp region
was cloned using Autographa californica multinucleocapsid nuclear polyhedrosis virus ( Ac MNPV) egt gene as a probe and southern hybridization method. Partially
594 nucleotides(nt) of Xba Ⅰ2 600 bp fragment within Pst Ⅰ 4 970 bp region was sequenced. The predicted peptide of the 594 nt exhibited a 45% and 86 5% amino acid identity with the egt polypeptides from Ac MNPV and Spodoptera littoralis multinucleocapsid nuclear polyhedrosis virus ( Sli MNPV)
