Study on Volatile Constituents of Populus deltoides with Different Resistant Ability to Batocera horsfieldi

The volatile constituents resistant to Batocera horsfieldi in 4 kinds of Populus deltoides were studied. Sixty eight constituents were determined by GC MS DS. It is discovered that the better the resistant ability to B.horsfieldi, the higher the content of alkyl hydrocarbon in the 4 varieties of P. deltoides tested. Twenty four main constituents were clustered. The result of clustering analysis coincides with the actual situation.
