Molecular chemical ecology on the coevolutionary process between insects and plants

生态适应机制从以下两个方面进行了研究，重点是与昆虫和植物之间的相互作用有关的信息化学因素。1)对抗性共同进化？燕尾蝶在产卵和幼虫取食过程中都能识别寄主植物，并具有复杂的植物代谢产物。利用电生理技术研究了味觉感知与宿主适应机制之间的关系。2)互惠共生？石豆兰属中的果蝇兰花使用特定的苯丙素挥发物吸引果实蝇属果蝇物种授粉。提出了植物物种形成过程中通过花内信息素的一种适应机制。

Ecological adaptation mechanisms were examined in the following two coevolutionary aspects, focusing on semiochemical factors associated with interactions between insects and plants. 1) Antagonistic coevolution ? Swallowtail butterflies recognize host plants with a complex mixture of specific plant metabolites both in oviposition and larval feeding processes. Relationships between taste perception and host adaptation mechanisms were examined using an ectrophysiological technique. 2) Mutualistic coevolution ? Fruit fly orchids in the genus Bulbophyllum attract Bactrocera fruit fly species for pollination using specific phenylpropanoid volatiles. An adaptation mechanism was proposed in the process of speciation via floral synomones.
