Pea (Pisum sativum) is a valuable legume crop widely cultivated for its nutritional and economic importance. However, greenhouse-grown pea plants are highly susceptible to a range of insect pests such as aphids, thrips, whiteflies, and moths, which can cause significant yield losses. In this study, we evaluated the efficacy of LED light traps as a sustainable and non-chemical method for pest control in a controlled greenhouse environment. Different wavelengths of LED lights—particularly blue (450 nm), ultraviolet (UV-A, 365 nm), and green (525 nm)—were tested to determine their attractiveness to target pest species. The traps were deployed at strategic locations in a randomized block design, and pest capture data were collected over eight weeks. Results indicated that UV-A and blue LED traps were most effective in reducing pest populations, with statistically significant reductions in aphid and thrip densities compared to the untreated control. Crop health and yield parameters also improved in LED-treated sections. This study demonstrates that LED light traps offer a promising, eco-friendly alternative to conventional pesticide applications for integrated pest management (IPM) in greenhouse pea cultivation.
