中文摘要:

【目的】 为营造蝴蝶飞舞的景观,本研究以青斑蝶Tirumala limniace Cramer为对象,探究了颜色和气味对该蝶觅食的引诱作用,根据引诱结果设计出一种在蝴蝶放飞后引诱蝴蝶的装置。该装置包括合适的假花颜色、引诱剂和彩灯颜色。【方法】 分别测定了不同颜色和挥发性信息化合物诱集到青斑蝶的数量。【结果】 视觉和嗅觉信号均对青斑蝶的觅食有引诱作用。视觉信号中,5种颜色假花引诱效果最好的是白色(9.0%),其次是黄色(3.7%)和红色(2.0%),粉红(1.7%)和紫色(1.0%)最差。3种灯光对青斑蝶的引诱效果都好于对照,其中引诱效果最好的是7色彩灯(9.3%),其次是粉红色(8.3%)和红色灯(7.0%)。嗅觉信号中,3种蜜源信息引诱剂引诱效果最好的是混合物(1% α-蒎烯+1%水杨酸甲酯+1% 1-辛醛)和对照(蜂蜜水),其次是1% 水杨酸甲酯,1% α-蒎烯最差。喷洒蜜源信息和蜂蜜水的红色、黄色和白色假花对青斑蝶的平均引诱率比不喷时分别提高了2.38倍、1.91倍和1.97倍,说明青斑蝶在觅食时以嗅觉信号为主,视觉信号为辅。【结论】 因此,该引诱装置选择的假花颜色为白色、黄色和红色;引诱剂为1% α-蒎烯+1% 水杨酸甲酯+1% 1-辛醛的混合物;彩灯为7色彩灯;较好的放飞方式是分多次放飞,每次放飞蝴蝶数量200~250只。该装置制作简便,造价便宜,可重复多次使用,对蝴蝶持续引诱效果较好,适合在网室内和野外蝴蝶放飞时使用。

英文摘要:

[Objectives]  In order to increase the abundance of butterflies at a specific site, we explored the roles of color and odor in attracting foraging adult Tirumala limniace Cramer. [Methods]  We designed, and tested the effectiveness of, equipment to attract released adult T. limniace. The equipment included appropriate colored artificial flowers, attractants and lights. The numbers of adults attracted by different colors and volatile compounds were compared. [Results]  Both visual and olfactory signals were attractive to foraging T. limniace. The most effective of the five different-colored artificial flowers was white (9.0%), followed by yellow (3.7%) red (2.0%), pink (1.7%) and purple (1.0%). All three colors of light were more attractive to T. limniace than the control. The most effective light was a combination of seven colors (9.3%), followed by pink (8.3%) and red (7.0%). The best olfactory attractants were a synthetic blend (1% α-pinene + 1% methyl salicylate + 1% 1-octanal) and the control (honey water), followed by 1% methyl salicylate. The worst olfactory attractant was 1% α-pinene. The average attraction rates of spraying attractants and honey water onto red, yellow and white flowers were 2.38, 1.91 and 1.97 times higher, respectively, than no attractants and honey water. These results indicate that foraging T. limniace are attracted by a combination of cues, and that olfactory cues are more important than visual cues. [Conclusion]  The most effective lure was comprised of white, yellow and red artificial flowers, a synthetic blend of olfactory attractants (1% α-pinene + 1% methyl salicylate + 1% 1-octanal), and a seven-colored lamp. It is best to successively release groups of 200-250 adult butterflies at a time. The equipment is easy to make, inexpensive and reusable. It continuously attracts butterflies and is suitable for use in net houses and outdoor habitats after butterflies have been released.
