该研究采用机械损伤、舞毒蛾 (Lymantria dispar) 幼虫取食、机械损伤后伤口涂抹舞毒蛾幼虫口腔分泌物三种方法处理合作杨 (P. simonii P. pyramibalis c.v)植株,以寻求引起树木对昆虫取食有效抗性反应的真正原因。应用TCT-GC/MS的技术分析了损伤处理24h后诱导挥发物的释放情况。结果表明一些挥发物,如(Z)-3-hexenyl acetate, decanal, decanal, 3-hexenyl isovalerate, nonanal, ocimene, and 2-cyanobutane均可由机械损伤和舞毒蛾幼虫取食诱导,而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仅能被昆虫取食所诱导。舞毒蛾口腔分泌物中的活性成分引起了释放的挥发物的差异。图1参14。
In this study, P. simonii P. pyramibalis cv plants were treated with mechanical damage, Lymantria dispar larvae feeding, and mouth wounds of gypsy moth larvae after mechanical injury. The real reason for feeding effective resistance. The TCT-GC / MS technique was used to analyze the release of volatiles after 24 h treatment. The results showed that some of the volatiles such as (Z) -3-hexenyl acetate, decanal, decanal, 3-hexenyl isovalerate, nonanal, ocimene, and 2-cyanobutane were all induced by mechanical damage and feeding on gypsy moth larvae, dimethyl-1,3,5,7-octatetraene, 2-methyl-6-methylene-1,7-octadien-3-one, caryophyllene, Isovaleronitrile, diethyl-methyl-benzamide, and dicapryl phthalate can only be eaten by insects Induced. The active ingredient in oral gills of Gypsy moths causes differences in volatiles released. Figure 1 reference 14.
