Development and Evaluation of a High-Efficacy Solar-Powered Light Trap for Rice Black Bug (Scotinophara Coartata) Management

Abstract

Rice black bugs (RBB) are a major pest causing significant yield losses in rice farms. This study investigates a novel solar-powered light trap for RBB control. The trap utilizes LEDs with different color temperatures (warm white and daylight) and incorporates an auto-response system for efficient operation. Performance evaluation over three months revealed the highest efficacy for the 50-watt warm white LED bulb (948 grams captured), followed by the daylight bulb (724 grams). However, the study found no significant difference between developing light traps with warm white and daylight LED in capturing RBBs. The trap's functionality was excellent, with low maintenance requirements. These findings suggest that the solar-powered light trap with warm white LEDs offers a promising, sustainable solution for RBB management in rice production.
