Molecular chemical ecology on the coevolutionary process between insects and plants

本文从两个方面探讨了昆虫与植物的生态适应机制，重点探讨了昆虫与植物相互作用的符号化学因素。1)拮抗协同进化？燕尾蝶在产卵和幼虫取食过程中通过复杂的特定植物代谢物来识别寄主植物。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)互惠的共同进化？球叶属的果蝇兰花利用特定的苯丙类挥发物吸引小实蝇类果蝇进行授粉。在物种形成过程中，提出了一种通过花激素的适应机制。

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.
