【摘要】 水分作为一种重要的环境因子,对陆地生物生长发育有着至关重要的作用。随着全球气候变暖,异常天气频发,水分胁迫也成为了影响农作物及其害虫生长发育的重要逆境胁迫。本文从水分胁迫对植食性昆虫的直接和间接影响进行阐述:从湿度、降雨量和土壤含水量角度讨论了水分胁迫对昆虫的直接影响;从水分影响植物和天敌角度,讨论了水分胁迫对植物-植食者性昆虫-天敌三营养阶层互作的间接影响,以期为理解农业害虫发生机制及其可持续治理决策提供研究信息和理论参考。更多还原

【Abstract】 Water as an important environment factor that plays a vital role in the growth and development of terrestrial life. With global warming and the consequent more frequent occurrence of abnormal weather conditions, water stress has become an important adverse stress factor which influences the growth and development of both plants and herbivores. This article describes both the direct and indirect influence of water stress on phytophagous insects. Direct effects include humidity, rainfall and soil moisture content and indirect effects include the effects of water stress on the host plants and the natural enemies of herbivorous insects. The object of this review is to provide a theoretical reference for understanding the effects of water stress on agricultural pests and to thereby improve their prevention and control.更多还原
