| 摘 要： | 除主组分反-10-十六烯醛(E10-16:Ald)外,还鉴定了桃蛀螟.Dichocrocis punctiferalis Guenée.性信息素的两种微量组分:顺-10-十六烯醛(Z10-16:Ald)和十六醛(16:Ald)。采用单腺体提取、毛细管柱气相色谱分析的方法测定16:Ald,E10-16:Ald和Z-16:Ald的相对比例为13.0:80.4:6.6。田间试验表明,16:Ald和Z10-16:Ald单个组分诱不到雄蛾.引诱力强的是三组分诱芯(16:Ald:E-10:Ald:Z-Ald为16:100:8)和两组分的诱芯(E-10:Ald:Z-10:Ald为100:8)。

| Abstract: | Along with the major component, (E)-10-hexadecenal (E10-16: Ald), two minor components, (Z)-10-hexadecenal(Z10-16:Ald) and hexadecanal (16;Ald) were identified as components of the sex pheromone of Dichocrocis punctiferalis Guenee. Analysis of single sex pheromone gland extracts by capillary gas chromatography indicated that the relative ratio of 16: Ald, E10-16 :Ald, and Z10-16:Ald was equal to 13. 0:80. 4:6. 6 respectively. Field trails indicated that Z10-16: Ald and 16: Ald alone caught no males. The most attractive was a blend containing 16:Ald, E10-16:Ald, and Z10-16;Ald at a ratio of 16:100:8, and a two-compound blend of E10-16:Ald and Z10-16:Ald at a ratio of 100:8. |
