| 为明确不同寄主和不同信息化合物对豆大蓟马的行为影响，本文应用“Y”型嗅觉仪测定了豆大蓟马雌成虫对两种寄主植物花和不同浓度(v/v)下11种化合物的趋向性反应，结果表明：豆大蓟马对豇豆花、10-4 烟酸乙酯、10-6 烟酸乙酯、10-2 橙花醇、10-2 芳樟醇、10-6 邻茴香醛和10-23-苯丙醛、10-43-苯丙醛具有极显著的趋向反应；对四季豆花和10-4 橙花醇具有显著的趋向反应；10-4 β-香茅醇、10-6 β-香茅醇和10-6 苯甲醛对豆大蓟马具有显著的驱避反应。不同浓度同一化合物对豆大蓟马的吸引作用也存在显著差异。实验结果可为进一步开发利用信息化合物田间防治豆大蓟马提供参考。 |
| 英文摘要: |
| In order to understand the effect of host plants and chemicals on the behavioral response of the bean flower thrips, Megalurothrips usitatus (Bagnall), in this study, the tropistic responses of adults female M. usitatusto eleven chemicals with different concentrations were measured using a Y-tube olfactometer in the laboratory. The results showed that cowpea flower, ethyl nicotinate with the concentration of 10-4, 10-6, nerol with the concentration of 10-2, linalool with the concentration of 10-2, orthoanisic aldehyde with the concentration of 10-6 and 3-benzenepropanal with the concentration of 10-2, 10-4 exhibited extremely significant attractive effect, kidney bean flower and nerol with the concentration of 10-4 exhibited significant attractive effect, whereas beta citronellol with the concentration of 10-4, 10-6 and benzaldehyde with the concentration of 10-6 exhibited significant repellent effect. From these results, it’s not difficulty to understand that different concentrations of the same chemical were significantly influenced the attractiveness to M. usitatus. The results of this experiment will facilitate the further study and practical application the chemicals to monitor and control thrips in the field. |
