| 中文摘要: |
| 在室内条件下采用机械损伤叶片( MW) 、外源水杨酸诱导( MeSA) 、扶桑绵粉蚧短期( S-MF) 及长期为害
( L-MF) 4 种方式处理棉花，对棉花植株释放的萜类化合物进行了定性与定量研究。结果表明，共有5 种萜类化合
物被定性检出，分别为α 蒎烯、β 蒎烯、长叶烯、A-柏木烯与雪松烯; 扶桑绵粉蚧的取食为害显著提高了棉花
α 蒎烯、β 蒎烯及A-柏木烯的释放量，并且新增加雪松烯与长叶烯的释放; 而叶片机械损伤与外源水杨酸诱导处
理在一定程度上也提高了α 蒎烯、β 蒎烯及A-柏木烯的释放量。本研究结果为合理利用虫害诱导植物挥发物进行
扶桑绵粉蚧的生物防治提供科学依据。 |
| 英文摘要: |
| The terpenoids emission of cotton plants were analyzed qualitatively and quantitatively under laboratory condition with the treatments of mechanical wounding ( MW) ，salicylic acid inducement ( SA) ，short-term mealybugs injury ( S-MF) ，and long-term mealybugs injury ( L-MF) ． The results showed thattotal 5 kinds of terpenoids were qualitatively identified，including α-Pinene，β-Pinene，( + ) -Longifolene，( -) -alpha- ( SG) ，and Cedrene. The infestation by the invasive mealybug Phenacoccus solenopsis elicited the Cedrene and ( + ) -Longifolene，and increased significantly the emission of α-Pinene，β-Pinene，and ( -) -alpha- ( SG) ． The treatments of MW and SA also increase partly the emission of α-Pinene，β-Pinene，and ( -) -alpha- ( SG) ． These results provide an important scientific basis for the biological control of P.solenopsis with the rational use of herbivore-induced plant volatiles. |
