Abstract: Chitosan is a non-toxic natural biopolymer derived from chitin,which is the second most abundant natural polymer after cellulose in the world.Chitosan is easily cheated with metal salts and form chitosan metal complexes(CMC).In this study,Masson Pine(Pinus massoniana)as test species,chitosan copper complex(CCC),modified chitosan copper complex(M-CCC)and CCB as wood preservatives to termite attack.The experiment was conducted according to AWPA E1-97(AWPA 1999)and GB/T18260-2000 in order to evaluate the termite resistance effects of CCC and M-CCC in comparison with CCB.Results showed that all of the chosen preservatives had good resistance against termites(Coptotermes formosanus),among which,M-CCC beheld the best,and the synthetical rating exceeded 100.

Key words: Pinus massoniana, termite resistance, Coptotermes formosanus, chitosan copper complex
