摘要/Abstract

摘要： "Y”型管嗅觉计及风洞测定试验表明,小麦植株、麦长管蚜(Sitobion avenae)、禾谷缢管蚜(Rhopalosiphum padi)对燕麦蚜茧蜂(Aphidius avenae)雌蜂的吸引作用较小,而有蚜植株及蚜害植株对其吸引作用较大,并以麦长管蚜有蚜植株的吸引作用最强.尽管该蜂对禾谷缢管蚜的寄生率极低,但由其危害诱导产生的挥发性信息化合物对该蜂仍具有较强的吸引作用.GC-MS鉴定结果表明,麦蚜取食诱导的挥发性信息化合物主要是2-莰烯、6-甲基-5-己烯-2-酮、6-甲基-5-己烯-2-醇、顺-3-己酰醋酸酯和水杨酸甲酯.其中6-甲基-5-己烯-2-酮和6-甲基-5-己烯-2-醇对燕麦蚜茧蜂的吸引作用最强,水杨酸甲酯无明显吸引作用.

Abstract: The responses of female Aphidius avenae to volatiles from undamaged wheat plant,Sitobion avenae and Rhopalosiphum padi,aphids-plant complexes and aphids damaged plant were investigated in wind tunnel and Y-tube olfactometer.The volatiles from undamaged wheat plant, S. avenae and R. padi were much less attractive to A. avenae than those from aphids-plant complexes and aphids-damaged plant.Although the parasitic rate was much lower,the R. padi-plant complexes and R. padi damaged plant were also attractive to A. avenae. Identification of volatiles by GC-MS showed that the main volatiles induced by aphids feeding were 2-camphene, 6-methyl-5-hepten-2-one, 6-methyl-5-hepten-2-ol, Z-3-hexenyl-acetate,and methyl salicylate,among which, 6-methyl-5-hepten-2-one and 6-methyl-5-hepten-2-ol were more attractive to A. avenae, while methyl salicylate was not attractive.
