昆虫对植物的选择性以及植物化学成分对昆虫的影响

The Selectivity of Insects to Plant and the Effects of Botanic Chemical Elements on Insects

植物与昆虫之间的关系一直被人们作为重要的研究目标。昆虫依靠绿色植物生存，植物通过自身的化学物质影响昆虫的进化方向，两者形成了复杂的协同进化关系。本文阐述了昆虫在定居、产卵、取食过程中运用不同的嗅觉、味觉、触觉刺激标准来选择适宜的寄主或寄主位置的方法，以及植物体内的化学成分对昆虫的营养作用和通过毒杀、拒食、招引天敌寄生蜂等方式抵御昆虫的进攻。

The relations between plants and insects are always looked as the important research object. The insect depends on the green plant to survive, while plant influents the evolution orientation of insects by the chemical matters. The two come into being the complex cooperative evolution relationships. This article expatiated the selective means of hosts or hosts position on insects by different stimulation standards of smell,taste and feeling during the process in settling,ovipositing and feeding, simultaneously the nutritional functions of chemical elements to insects together with the resisting to insects by poison,rejection and attracting the natural enemy autoecious bees.
