UV对昆虫的生物学效应及昆虫适应机制

Biological effects of ultraviolet light on insects

紫外光(Ultraviolet light,UV)源于太阳辐射,是一种重要的环境因子,昆虫作为地球生态系统中的重要参与者其生命活动也会受到UV辐射的影响。UV辐射对昆虫造成的生物学效应除与波长、辐射强度等光学特性有关,还与其他非生物因素和生物因素有关。昆虫长期与UV共存,也进化出了行为适应、生理适应等各种抵御UV辐射的能力。本文从多方面综述了UV对昆虫的生物学效应,以及昆虫对UV胁迫的适应机制,有利于认识和理解昆虫应对物理胁迫的生理对策,为丰富和完善害虫物理防治策略提供科学依据,对促进害虫物理防治产业的发展具有重要意义。

Ultraviolet light (UV) is an important environmental factor derived from solar radiation. Insects are an important part of the earth's ecosystem and are affected by UV radiation. Biological effects of UV radiation on insects are not only related to its optical characteristics, such as wavelength and radiation intensity, but also to abiotic and biological factors. Insects have evolved with UV light, and consequently have evolved behavioral and physiological adaptations to resist UV radiation. This paper reviews the biological effects of UV light on insects and the mechanisms insects use to withstand UV stress, both are part of the physiological measures insects use to withstand physical stress in general. It also provides a scientific basis for improving non-chemical pest control methods and promotes the development of non-chemical pest control technology.
