Volatile organic compounds can play a dominant role in the ecology of plants. Herbivore-induced plant volatiles (HIPVs) are well documented for a number of agronomic plants, as is their role in attracting parasitoids and predators, thus providing indirect defense for the emitting plant. What is far less well know is the influence of HIPVs among different types of insect herbivores attacking the same plant, and whether insect herbivores can habituate to these olfactory signals from their host plants. Key parameters of global climate change - increasing CO2 and temperature - are predicted to alter plant defensive chemistry and may make crops more vulnerable to pests. Effects of these atmospheric factors on HIPVs has been little studied. I propose to explore HIPVs from three perspectives, that of the plant, the herbivore community and individual herbivores. Specifically, the objectives of the proposed research are:

挥发性有机化合物在植物生态学中起主导作用。食草动物诱导的植物挥发物（HIPVs）是有据可查的一些农艺植物，因为是他们的作用，吸引寄生虫和捕食者，从而提供间接防御的排放植物。 目前还不太清楚的是，HIPV在不同类型的植食性昆虫攻击同一种植物时的影响，以及植食性昆虫是否能够适应来自其宿主植物的这些嗅觉信号。 据预测，全球气候变化的关键参数--二氧化碳和温度的增加--将改变植物的防御化学，并可能使作物更容易受到害虫的影响。 这些大气因素对HIPV的影响研究很少。 我建议从三个角度来探讨HIPVs，即植物，食草动物社区和个体食草动物。 具体而言，拟议研究的目标是：
