摘要: 大气平流层臭氧的破坏直接增强了到达地面的太阳紫外线,特别是紫外B辐射的强度。紫外B辐射增强将对生态系统产生深刻的影响。本文综述了近年来紫外B辐射增强对昆虫影响的研究,分析了紫外B辐射增强可能产生的对植食性昆虫的直接和间接影响及其机制,就紫外B辐射增强对昆虫影响方面迫切需要阐明的一些问题进行了讨论。

Abstract: The depletion of stratospheric ozone leads to an increase of solar ultraviolet (UV), especially UVB (280~320 nm) reaching the Earth’s surface, giving profound impacts on the ecosystems of the Earth. This paper reviewed the recent studies about the effects of elevated solar UV-B radiation on insects, analyzed the direct and indirect effects of this radiation on herbivorous insects and their mechanisms, and discussed the related issues to be further approached.
