Abstract:

[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.
