Three treatments including mechanical damage, Lymantria dispar attacking and daubing oral secretions of the in-sects on mechanically damaged cut were conducted on Populus simonii譖opulus pyramibalis c.v. in order to find the genuine reason leading to effective resistance response of tree to insects attacking. The release situation of the induced volatiles of the plant was analyzed by TCT-GC/MS at 24 hours after damages. The results indicated that some of the volatiles such as (Z)-3-hexenyl acetate, decanal, 3-hexenyl isovalerate, nonanal, ocimene, and 2-cyanobutane can be induced by both insects attack-ing and mechanical damage, while 2,6-dimethyl-1,3,5,7-octatetraene, 2-methyl-6-methylene-1,7-octadien-3-one, caryophyllene, Isovaleronitrile, diethyl-methyl-benzamide, and dicapryl phthalate were only induced by insects attacking. Such difference in volatiles was attributed to that there existed active components in oral sections of the larvae of Lymantria dispar 展开更多
