The pathogenicity and genome sequence of isolate LdMNPV-HrB of the gypsy moth alphabaculovirus, Lymantria dispar multiple nucleopolyhedrovirus from Harbin, Heilongjiang, China, were determined. A stock of this virus from one passage through the gypsy moth New Jersey Standard Strain (LdMNPV-HrB-NJSS) exhibited 6.2- to 11.9-fold greater pathogenicity against larvae from a Harbin colony of L. dispar asiatica than both Gypchek and a Massachusetts, USA LdMNPV isolate (LdMNPV-Ab-a624). Sequence determination and phylogenetic analysis of LdMNPV-HrB and LdMNPV-HrB-NJSS revealed that these isolates were most similar to other east Asian LdMNPV isolates with 98.8% genome sequence identity and formed a group with the east Asian LdMNPV isolates which was separate from groups of isolates from Russia, Europe, and USA.
