Abstract
The oriental Fruit Fly (Bactrocera dorsalis) poses a significant threat to various crops, leading to substantial agricultural losses and necessitating the development of more effective pest control methods. Traditional traps and manual interventions are labor-intensive and often ineffective, highlighting the need for innovative solutions. This study addresses this problem by developing a solar-powered automated scent lure traps as a sustainable alternative for controlling the Oriental Fruit Fly in agricultural settings.
The study was conducted across three testing sites: CRRDC, RET, and CAg. Manual traps were made and deployed for manual intervention phase, which spanned 14 days. The pest occurrence indices were recorded to evaluate the effectiveness of different chemical attractants. In all testing areas, the combined attractant of Methyl Eugenol (Me) and Silver Nanoparticles (AgNP) emerged as the most effective lure, consistently outperforming single attractants. Moreover, the hotspots or the location where the fruit flies accumulate at the different testing sites were pinpointed as the high-infestation areas for targeted trap deployment for mechanical intervention phase. These identified hotspots were visually presented on a map retrieved from Quantum Geographic Information System (QGIS). The mechanical intervention phase involved the deployment of the developed solar-powered automated scent lure traps over an 8-day period. Statistical analysis confirmed that the combined chemical attractant significantly increased fruit fly captures and that the automated traps consistently outperformed manual traps across all testing sites. The automated scent lure trap was evaluated by determining the trapping effectivity and capacity, further proving its effectiveness compared to the manual traps.
The results of the study highlight the potential of automated traps to to revolutionize pest management practices by offering continuous operation with minimal human intervention. Integrating such technologies into agricultural pest control strategies can enhance efficacy and sustainability. Further research and collaboration are recommended to optimize trap design, attractants and operational parameters to improve efficacy and scalability in fruit fly control efforts.
