This article presents a scientific analysis of the anatomical and morphological structure of aphids, which are among the major pests affecting plants, as well as their negative impact on plant organisms. The feeding behavior of aphids on vegetative plant organs leads to disruption of photosynthesis, transmission of viral diseases, and reduction in crop productivity. In addition, the effects of ultraviolet (UV) radiation, particularly in the UV-C and UV-B ranges, on insect organisms were examined, focusing on damage to both external (exoskeleton) and internal systems (nervous, digestive, and visual systems). The results indicate that UV radiation can disrupt cellular structures, thereby inhibiting the growth and reproduction of aphids. This method is considered environmentally safe and effective, offering a promising alternative to chemical insecticides.
