The gastropod mollusk Physa acuta is known to be an invasive species. Exotic species cause economic, social and biological damage to ecosystems. Due to their characteristics, including life history, reproductive strategy and biotic potential, these populations grow in a way that harms the environment in which they invaded. Considering the importance of these molluscs, an experiment was carried out in the laboratory to verify the effect of lamps, with different wavelengths, on the mollusk Physa acuta. The objective was to verify the viability of organisms under experimental conditions, with different lamps of different wavelengths. The lamps used were warm white light, cold white light, UVC and UVA, in addition to the Control Group, which received natural light. For the groups exposed to Cold White Light and Ultraviolet A, the performance of Physa acuta was lower than the Control and Warm White Light groups, but much higher than the Ultraviolet C group, which presented 100% mortality in just one week.
