Figure 2. The NJ tree (L) and MP tree (R) of E. obliqua and two outgroup species based on COI sequence haplotypes.

Numbers above the nodes indicate bootstrap support. The outgroups used were B. suppressaria and S. subpunctaria. The QZ1 haplotype was shared by all thirteen populations insensitive to the EoNPV virus within Clade II; the HZ2 haplotype was shared by all four populations susceptible to the virus within Clade I; and other haplotypes were unique.
