青斑蝶Tirumala limniace成虫颜色偏好性研究

【目的】明确青斑蝶Tirumala limniace雌、雄成虫对颜色的偏好性,可以为此蝴蝶人工饲养时的合理环境条件设定提供必要的理论支持。【方法】本研究通过在室内和野外对青斑蝶成虫对6种颜色(白色、红色、绿色、黄色、蓝色和紫色)光源的选择行为进行观察,明确青斑蝶成虫对不同颜色的偏好性。【结果】(1)在室内和在野外雌、雄成虫均优先选择黄色。(2)雌雄成虫在野外无其它光源干扰下对黄色的选择性强于室内。(3)单色光源照明和多种不同颜色光源同时存在下,成虫对颜色的偏好程度存在差异:当只有单色光源照明时,成虫对颜色的偏好程度为黄色>绿色=红色≥蓝色≥紫色;当不同颜色光源同时存在时,成虫对颜色的偏好程度则为黄色>蓝色≥绿色=红色≥紫色。(4)在不同颜色光源同时存在时,配对后的雌成虫表现出了比雄成虫更强的颜色选择性:雌成虫对黄色光源的选择性强于雄成虫,且其未产生颜色选择的成虫数量也少于雄成虫。【结论】青斑蝶成虫存在对黄色选择的颜色恒常性,野外成虫对颜色的选择性强于室内,雌、雄成虫对偏好颜色选择性存在性别差异。

Color preferences of adult Tirumala limniace

Objectives] To study butterfly color preferences in order to determine the optimal environmental conditions for their captive propagation and utilization.Methods] Preferences of adult female and male T. limniace for six kinds of colored lights: white, red, green, yellow, blue and purple, were determined in both the laboratory and the field. Results] (1) Males and females were more likely to choose yellow in both laboratory and field experiments. (2) The preference for yellow was stronger in the field, where there were no other light sources, than in laboratory. (3) The strength of color preference of adults exposed to single-colored lights differed from that of those exposed to multiple-colored lights. The relative preference of adults exposed to single-colored lights was: yellow > green=red≥blue≥purple, whereas that of adults exposed to multiple-colored lights was: yellow > blue>green=red≥purple. (4) When adults were exposed to multiple-colored lights, females that had mated showed clearer color preferences than males, a stronger preference for yellow than males, and fewer females than males had no color preferences.Conclusion] T. limniace displays a clear preference for the color yellow over green, red, blue and purple. Color preferences were stronger in the field than in the laboratory. Some sexual differences in color preferences were apparent.
