Optimization of LED light traps enhances pest selectivity and energy efficiency in shallot agroecosystems
Abstract
Artificial light traps are crucial for pest monitoring, but their ecological impact and efficiency depend heavily on the light spectrum. This study evaluated the spectral effectiveness, ecological selectivity, and energy efficiency of light-emitting diode (LED) traps for managing major shallot pests in a tropical agroecosystem in South Sulawesi, Indonesia. A randomized block design field experiment with three replications was conducted to test three LED spectra: white (380–700 nm), yellow (570–590 nm), and purple (380–750 nm). Insect capture rates, ecological selectivity indices, and energy consumption were analyzed using ANOVA and Tukey’s HSD test. The results demonstrated that LED color significantly influenced both total insect capture and species-specific attraction. White LEDs recorded the highest total insect abundance but exhibited low target specificity. In contrast, yellow LEDs demonstrated superior selectivity for key sucking pests, specifically Thrips tabaci and Aphis gossypii, achieving the highest Target Selectivity Percentage (TSP) and Ecological Safety Index (ESI). While white LEDs showed the highest overall capture efficiency per watt-hour, yellow LEDs were more energy-efficient per target pest captured. These findings conclude that wavelength-specific yellow LED traps offer a highly selective, ecologically safe, and energy-efficient tool for integrated pest management (IPM) programs in shallot cultivation.
