植食性昆虫对寄主植物的定向行为研究进展

Research Progress of Behavioral Orientation of Phytophagous Insects to Their Host Plants

植物挥发物是引导植食性昆虫寄主定向行为的主要因素,植物的形状和颜色等视觉线索在植食性昆虫寄主定位中也起重要作用,二者协同作用引导昆虫到达寄主植物后,又有触觉、味觉等接触化学感受器的作用,植物在遭受植食性昆虫危害后所产生的挥发物,对植食性昆虫也有不同程度的影响。对植食性昆虫寄主定向行为的了解,有助于发展对植食性昆虫的行为调控技术,提高害虫的综合防治水平。

Plant volatiles are the main cues used by phytophagous insects in orientation to their host plants, and the visual cues such as plant shape and color also played an important role in the process. After phytophagous insects arrived at their host plants under the interaction between these two cues, the sense of touch and gustation of phytophagous insects played a role in discerning their host plants. On the other hand, the volatiles emitted by host plants damaged by phytophagous insets can also have an inverse effect on phytophagous insects. Understanding the behavioral orientation of phytophagous insects to their host plants can help to develop techniques for their behavior control so as to enhance the efficiency of integrated pest control.
