The soil environment quality of woodland with different parent materials(limestone,dolomite limestone,limestone shale,dolomite,limestone sand inclusion shale) in Kasta mountain area was assessed with Analytic Hierarchy Process and Principal Component Analysis *** results indicated that the soil fertility quality of the soil developed from limestone shale was the best,and the soil developed from dolomite limestone was the *** soil developed from limestone shale showed the best heavy metals quality,and the soil developed from dolomite was the *** soil developed from limestone shale had the best stand condition quality,and the soil developed from limestone sand inclusion shale was the *** results also showed that the order of the soil environment quality was: limestone shale>limestone>dolomite limestone>dolomite>limestone sand inclusion shale.

One virus of Diprion nanhuaensis was separated from the died D. nanhuaensis, the virus belongs to nuclear polyhedrosis virus, bacilliform virus particle in inclusion body appears SNPV(single nucleocapsid polyhedrosis virus) by electron microscopy. The structure of inclusion body appears polyhedron and close to rotundity, and the length of diameter of inclusion body ranges 0.5～1.0 μm, a little proportion of them shows anomalistic form. There are many bacilliform virus particles in one inclusion body. Six virus particles in one inclusion body take up a large proportion and one virus particle in one inclusion body only takes up a small proportion, the length of virus particle ranges 125～200 nm,and the length of diameter of virus particle ranges 25～30 nm. Meanwhile,the virus can infect the 2～3 instars Neodiprion xiangyunicus and the 2～3 instars D. nanhuaensis in laboratory.
