The long-term goal of this research is to elucidate the roles played by plant chemistry in the ecology and evolution of a single taxon of herbivorous insects, namely the butterfly family Papilionidae. Emphasis is placed on the chemical basis of plant recognition by ovipositing females. Identification of contact oviposition stimulants for the black swallowtail, Papilio polyxenes (tribe Papilionini), will be extended from carrot, Daucus carota, to other umbelliferous plants to assess the specificity of chemical response profiles in one insect species. Identification of contact stimulants will also be carried out with two subspecies of a close relative, P. machaon, which show apparent steps in a host switch from the Apiaceae to the Asteraceae (genus Artemisia). Identification of contact stimulants from Aristolochia species for Battus philenor, a more distant relative (tribe Troidini), will be completed and followed by similar studies with Eurytides marcellus, an Asimina-feeding species belonging to yet a third tribe (Graphiini). These comparative studies will permit testing of the long-held hypothesis that the adaptive radiation of swallowtail butterflies has been constrained by preadaptation to particular chemical compounds that are used as behavioral cues in host recognition.

这项研究的长期目标是阐明植物化学在草食昆虫单一分类单元（即蝴蝶科蝶形花科）的生态和进化中所发挥的作用。 重点放在产卵雌性植物识别的化学基础上。 黑色燕尾凤蝶（凤蝶族）接触产卵刺激剂的鉴定将从胡萝卜、胡萝卜扩展到其他伞形植物，以评估一种昆虫化学反应谱的特异性。 还将对近亲 P. machaon 的两个亚种进行接触刺激物的鉴定，这两个亚种显示了从伞形科到菊科（蒿属）的宿主转换的明显步骤。 对马兜铃属植物中对马兜铃属物种的接触兴奋剂的鉴定工作将完成，该物种是一个更远亲（Troidini 部落）的 Battus philenor，随后将对 Eurytides marcellus 进行类似的研究，Eurytides marcellus 是属于第三个部落（Graphiini）的一种以 Asimina 为食的物种。 这些比较研究将允许检验长期以来的假设，即燕尾蝴蝶的适应性辐射受到对用作宿主识别行为线索的特定化合物的预适应的限制。
