| 摘 要： | 在昆虫与植物的相互作用关系中 ,次生代谢物质被看作是植物对昆虫的化学防御机制之一。然而 ,植食性昆虫能够在寄主植物上完成生长发育过程 ,其重要原因就在于虫体自身具有相应的对寄主植物次生代谢物质的代谢适应能力 (钦俊德 ,1 995 ;1 987)。昆虫对待寄主植物中有毒的次生代谢物质可通过羧酸酯酶 (Ｅ .Ｃ .3 1 1 2 )、谷胱甘肽转移酶 (Ｅ .Ｃ .2 5 1 1 8)、多功能氧化酶 (Ｅ .Ｃ .1 1 4 1 4 1 )等解毒酶 (Ｄａｕｔｅｒｍａｎｅｔａｌ.,1 988) ,将其转化为非毒性物质 ,从而使昆虫能够适应取食对象。在烟草夜蛾 (Ｈｅ ｌｉｏｔｈｉ…

| Abstract: | Activities of carboxylesterase and glutathione S transferase in Anoplophora glabripennis larvae feeding on eight different kinds of poplar trees were tested. The results showed that the activities of the two enzymes were significantly different when the larvae feeding on different poplar trees. The contents of fourteen secondary metabolites in eight kinds of poplar trees were also tested with the method of high pressure liquid chromatography (HPLC). Stepwise regression analysis was carried out to test the relationship between the activities of the enzymes and secondary metabolites of poplar trees. The analysis results demonstrated that the contents of benzoic acid and catechin decreased together with the increase of carboxylesterase activity while the contents of catechol increased, but the content of p hydroxybenzoic acid decreased together with the increasing of glutathione S transferase activity while the content of phenol, coumaric acid, syringic, salicylic acid and salicin in poplar trees increased. |
