在分析了ＨａＳＮＰＶ和ＥｏＳＮＰＶ多角体蛋白基因核苷酸序列的基础上，通过ＭＡＬＩＧＮ程序，比较了目前已发表的２６种杆状病毒包涵体蛋白的序列，ＨａＳＮＰＶ与ＨｚＳＮＰＶ亲缘关系十分接近，两者ａａ序列同源性达９７．６％，ｎｔ序列同源性达９７．４％；ＥｏＳＮＰＶ与黄杉毒蛾核型多角体病毒（Ｏｐ－ＳＮＰＶ）的同源性为最高，ｎｔ序列的同源性为８３．０％，ａａ序列达９４．７％，与其它２０种鳞翅目ＮＰＶ的同源性也很高，ｎｔ序列同源性为７２．６％～８１．９％，ａａ序列为８３．７％～９３．９％；与ＧＶ的同源性较低，为４８．４％～５４．９％；而与锯叶蜂核型多角体病毒（ＮｓＳＮＰＶ）的同源性为最低，仅４４．９％。应用Ｃｌｕｓｔａｌ程序建立了一个包括了２６种包涵体蛋白的系统树，确定了新测定的ＥｏＳＮＰＶ和ＨａＳＮＰＶＰｈ在包涵体蛋白基因系统树中都属于ＮＰＶ中的ＧｒｏｕｐⅡ分枝。
Based on the analysis of the nucleotide sequences of the polyhedrin genes of HaSNPV and EoSNPV, the sequences of 26 published baculovirus inclusion bodies were compared by MALIGN program. The genetic relationship between HaSNPV and HzSNPV was very close, The sequence homology was 97.6% and the sequence homology was 97.4%. The homology of EoSNPV with Op-SNPV was the highest, and the homology of nt sequence was 83.0% for aa, 94.7% for aa, and high homology with other 20 lepidopteran NPVs. The homologies of nt sequences were 72.6% -81.9% and aa sequences were 83%. 7% -93.9%. The homology with GV was low (48.4% -54.9%), while it was the lowest (44%) with the NsSNPV .9%. A phylogenetic tree consisting of 26 inclusion body proteins was constructed using the Clustal program and confirmed that the newly sequenced EoSNPV and HaSNPVPh belonged to Group II branches in NPV in the inclusion body protein phylogenetic tree.
