Light traps are devices designed to attract and capture insects using light. They typically consist of a light source, such as a bulb, that emits ultraviolet light, which many insects find irresistible. When insects fly towards the light, they are often funneled into a collection container, making it easier for researchers to study them. These traps are commonly used in entomology, the study of insects, to monitor insect populations and behavior. They can help scientists understand the distribution of species and the impact of environmental changes. Light traps are also useful in agriculture for pest control, allowing farmers to manage harmful insect populations effectively.
