摘要
[目的]找出吸引青斑蝶取食的关键化合物。[方法]通过田间观察测定了青斑蝶对蜜源植物马缨丹和马利筋的花部挥发物α－蒎烯、水杨酸甲酯，花部挥发物类似物1－辛醛、桉叶油醇、萜品醇，以及前人报道的花中普遍存在的苯甲醛的取食反应。[结果]无论是6种单一化合物和α－蒎烯、水杨酸甲酯、1－辛醛、桉叶油醇化合物组合还是不同剂量α－蒎烯和水杨酸甲酯，青斑蝶对这些挥发物均表现出一定的取食反应，但取食次数均未显著高于去离子水，且不同化合物之间无显著差异。[结论]青斑蝶在取食时可利用多种气味信号。
Abstract
Objective] The aim was to find out the key compounds that attracted Tirumala limniaceto flowers.[Method] The nectar-flowers Lantana camara and Asclepias curassavica volatiles like α-pinene and methyl salicylate, and flower-part volatiles analogues like n-capryl alde-hyde,eucalyptol, and terpineol, and the common volatiles of flower like benaldehyde were used to observe the feeding responses of T.limni-ace.[ Result] All the tested single compound, mixed compounds and different dose of α-pinene and methyl salicylate were attractive to adults. But the foraging preferences of T.limniace to different single compound, to mixed compounds and to different dose of α-pinene and methyl sa-licylate were not significantly higher than that of deionized water.Moreover, there were also no significant differences between different com-pounds.[Conclusion] Foraging adults can be attracted by a variety of chemical signals.
