| 中文摘要: |
| 梨小食心虫Grapholita molesta（Busck），是一种世界性的蛀果害虫。利用产卵选择试验研究了15种寄主植物挥发物对梨小食心虫受孕雌虫的产卵引诱活性。室内试验表明:受孕雌虫对不同挥发物的产卵选择趋性不同,其中对叶醇和己酸丁酯表现出明显的产卵选择趋性。为验证寄主挥发物对受孕雌虫的实际诱捕效果，进行了田间诱捕试验。结果发现，挥发物中己酸丁酯、苯甲腈、叶醇、E-2-己烯醛以及乙酸己酯诱捕到的雌虫均为受孕雌虫，显著高于空白对照及其他物质，其中己酸丁酯的平均诱捕量最多，苯甲腈次之， E-2-己烯醛、乙酸己酯这两种物质的平均诱捕量分别为第三、第四，叶醇的诱捕量低于乙酸己酯，其余物质的诱捕量均较低。综合室内及田间试验结果发现，寄主植物挥发物对受孕雌虫的引诱作用也随它们之间的作用距离表现出一定的差异性 |
| 英文摘要: |
| The Grapholita molesta (Busck), is a significant cosmopolitan pest and occurred in fruit growing areas around the world .The effect of 15 host-plant volatiles to the spawning activity of pregnant females of oriental fruit moth was examined. The result showed that pregnant females had different taxis response and selective propensity to these host-plant volatiles, which Z-3-hexen-1-ol and butyl hexanoate showed obvious attractability to pregnant females. To verify the actual trapping effect of the host-plant volatiles, the filed tests were conducted. The results showed that the females of trapping of Z-3-hexen-1-ol,butyl hexanoate,E-2-hexenal、hexyl acetate and benzonitrile were all pregnant females, and the amount of trapping was significantly higher than the control and other host-plant volatiles. The average amount of trapping of butyl hexanoate was the highest and the butyl hexanoate followed, the amount of trapping of E-2-hexenal and hexyl acetate were third and forth in all host-plant volatiles, the average amount of trapping of Z-hexen-1-ol followed hexyl acetate, and the amount of trapping of other volatiles were lower. The comprehensive results showed that, attractiveness of the host plant volatiles to pregnant females of oriental fruit moth was also different when the distance between them was changed. |
