红锯蛱蝶觅食过程中的视觉和嗅觉反应
[目的]探讨颜色和气味对红锯蛱蝶觅食的引诱作用。[方法]分别测定不同颜色和挥发性信息化合物对红锯蛱蝶的引诱效应。[结果]实验发现:视觉和嗅觉信号对红锯蛱蝶觅食均有引诱作用,红、粉、黄、紫、白5种颜色中,红锯蛱蝶明显偏好白色假花(占总访问次数的56.67%),对黄色(20.00%)和粉红色(15.00%)假花的趋性次之;灯光的选择中,夜晚的引诱效果好于白天,粉红色灯光(42.22%)对红锯蛱蝶的诱集效果最好;红锯蛱蝶对蜜源信息挥发物有明显的趋性,无气味时,访花次数较少,添加气味后,访花次数急剧增加,其中,1%水杨酸甲酯(35.17%)和化合物组合(1%α-蒎烯+1%水杨酸甲酯+1%1-辛醛)(3...

Summary: | [目的]探讨颜色和气味对红锯蛱蝶觅食的引诱作用。[方法]分别测定不同颜色和挥发性信息化合物对红锯蛱蝶的引诱效应。[结果]实验发现:视觉和嗅觉信号对红锯蛱蝶觅食均有引诱作用,红、粉、黄、紫、白5种颜色中,红锯蛱蝶明显偏好白色假花(占总访问次数的56.67%),对黄色(20.00%)和粉红色(15.00%)假花的趋性次之;灯光的选择中,夜晚的引诱效果好于白天,粉红色灯光(42.22%)对红锯蛱蝶的诱集效果最好;红锯蛱蝶对蜜源信息挥发物有明显的趋性,无气味时,访花次数较少,添加气味后,访花次数急剧增加,其中,1%水杨酸甲酯(35.17%)和化合物组合(1%α-蒎烯+1%水杨酸甲酯+1%1-辛醛)(32.42%)对红锯蛱蝶的引诱效果最明显。[结论]研究表明:视觉和嗅觉信号均在红锯蛱蝶的觅食过程中发挥作用,但觅食时更侧重依赖嗅觉信号选择合适的食物。红锯蛱蝶明显偏好白色,可能与白色的强反光能力有关。 |

Bibliography: | 11-1221/S [ Objective ] To study the responses of Cethosia biblis to color and odor in its foraging behavior. [ Meth- od] The attractive effect of C. biblis by different colors and volatile compounds were investigated respectively. [ Re- sult ] It was found that both visual and olfactory signals had effects on the foraging behavior of C. biblis. Among five colors, C. biblis showed a clear preference to white (the proportion was 56.67% ), followed by yellow (20.00%) and pink ( 15.00% ). In light trapping test, the attractiveness of different color light at night was better than those in daytime generally; and the pink light attracted the largest number of butterfly (42.22%). Olfactory signals were significantly attractive to the adults of C. biblis. The models scented with 1% methyl salicylate (35.17%) and syn- thetic blends (1% α-pinene + 1% methyl salicylate + 1% 1-octanal) (32.42%) attracted significantly more a- dults than the odorless ones. [ Conclusion] It is concluded that, both olfactory and visual cues |
