斑马燕尾蝶（Eurytides marcellus）通过单一化合物3-咖啡酰-粘-奎尼酸刺激产卵（1）。对寄主三叶草（Asiminatriloba）叶的水提物的分析表明，它们含有刺激物1、其异构体（2）以及黄酮类化合物芦丁（3）和烟草花碱（4）作为主要成分。我们比较了化合物1-4在整个生长季节的四个不同时间在寄主植物的顶生叶（TL）和展开叶（EL）中的浓度。在春季，1的浓度是最高的TLs，黄酮类化合物检测不到或存在于低水平。然而，随着季节的推移，类黄酮的浓度增加，在夏末达到最大值，然后随着植物开始衰老而下降。TL和EL之间这些化合物的浓度也存在显著差异。在一个选择与模型叶测定，我们测试了等量的后二氯甲烷水提取物在春季（5月）和秋季（9月）。9月提取物收到的方法和鸡蛋明显减少。温室盆栽试验中，在三叶草植物中，蝴蝶选择一些叶子产卵，而另一些则被拒绝或忽略。分析表明，化合物1在三种叶片中的浓度没有显著差异。然而，黄酮类化合物（3和4）在被忽略的叶子中显著更高。使用模式植物的多项选择试验表明，黄酮类化合物和兴奋剂的浓度是重要的，在评估主机的适合性。随着1浓度的降低，方法逐渐减少。即使在高浓度的兴奋剂1的存在下，较高量的黄酮类化合物也会阻止产卵。在较低浓度的1，添加低剂量的黄酮类化合物阻止产卵。因此，结果表明，蝴蝶使用定性和定量的信息，这些化合物来评估主机质量。这种行为可能是为了利用其宿主A的化学物质的季节性变化而进化的。三叶草
Zebra swallowtail (Eurytides marcellus) butterflies are stimulated to oviposit by a single compound, 3-caffeoyl-muco-quinic acid (1). Analysis of the aqueous extracts of the leaves of the host, Asimina triloba, showed that they contained stimulant 1, its isomer (2), and the flavonoids rutin (3) and nicotiflorine (4) as major components. We compared the concentrations of compounds 1–4 in terminal leaves (TL) and expanded leaves (EL) of the host plants at four different times throughout the growing season. In spring, the concentration of 1 was highest in TLs, and flavonoids were not detectable or present at low levels. As the season progressed, however, the concentrations of flavonoids increased, reached maxima by late summer, and then decreased as the plants started senescing. There were also significant differences in the concentrations of these compounds between TLs and ELs. In a choice assay with model leaves, we tested equivalent amounts of post-dichloromethane aqueous extracts made in spring (May) and in fall (September). September extracts received significantly fewer approaches and eggs. In greenhouse experiments with potted A. triloba plants, the butterflies chose some leaves to lay eggs, while others were rejected or ignored. Analyses showed that the concentrations of compound 1 were not significantly different in the three kinds of leaves. The flavonoids (3 and 4), however, were significantly higher in the leaves that were ignored. Multiple-choice tests using model plants suggested that concentrations of both flavonoids and stimulant were important in assessing host suitability. There was a gradual decrease in approaches as the concentration of 1 decreased. Higher amounts of flavonoids deterred egg laying even in the presence of high concentrations of stimulant 1. At lower concentrations of 1, the addition of low doses of flavonoids deterred egg laying. Thus, the results suggest that the butterflies use both qualitative and quantitative information about these compounds to assess host quality. This behavior may have evolved to take advantage of seasonal variation in the chemistry of their host, A. triloba.
