虫害诱导植物挥发物(HIPVs)对植食性昆虫的行为调控

虫害诱导植物挥发物(herbivore induced plant volatiles,HIPVs)具有植物种类、品种、生育期和部位的特异性,也具有植食性昆虫种类、虫龄、为害程度、为害方式和其他一些环境因子的特异性。由于其释放量明显大于健康植株,因此更易被天敌、害虫以及邻近的植物等所利用,从而调节植物、植食性昆虫与天敌三者之间的相互作用关系,增强植物在自然界的生存竞争能力。本文对HIPVs在植食性昆虫寄主定位行为中的作用、HIPVs对植食性昆虫的种群调控功能及其应用现状2个方面加以综述,并在展望中对目前研究中存在的一些问题进行了探讨。

Behavior regulation of herbivores by herbivore induced plant volatiles ~ HIPVs）

The composition of herbivore induced plant volatiles （HIPVs） varies between different plant species, varieties, growth periods and different tissues within a plant. The characteristics of HIPVs depend on the species of herbivore, which herbivore instars are present, the degree and pattern of damage and some other environmental factors also. The release of HIPVs from damaged plants is much higher than that from healthy plants, making them more likely to be detected by herbivores, their natural enemies, neighboring plants and so on. HIPVs could be used to manipulate the tri-trophic interaetion between plant, herbivores and natural enemies of herbivores, thereby strengthening the survival capability of the plant. The role of HIPVs in host searching and population regulation and the applications of this to pest control are summarized in this paper. Some related study questions are also discussed.
