Abstract
The intensification of environmental pollution and the destruction of the ozone layer has increased the amount of ultraviolet (UV) radiation reaching the surface daily, which resulted in great selective pressure for plants and insects in the biosphere. UV light stress can seriously affect the growth and development of insects, such as growth retardation, fecundity weakening, and life span shortening. Protective and detoxification enzymes, which are two important adaptive enzyme systems in insects, play a dominant role in regulating insect response to UV stress. On the basis of domestic and foreign studies on the changes in detoxification and protective enzymes under UV light stress, the effects of UV stress on the activities of protective and detoxification enzymes in insects and the mechanism of insect response to UV light stress are introduced in this study. Thus, this work provides reference suggestions for the application of UV light in comprehensive pest control and promotes the development of green prevention and control technology.
