Optimizing CO2-Based Mosquito Control via Anaerobic Plant Fermentation and Molasses Dose Recommendation

Mosquitoes pose a serious threat due to the diseases they transmit, such as dengue, malaria, and chikungunya. In the Philippines, dengue remains the most prevalent, with 437,089 cases reported annually. Studies show that UV traps are less effective when used alone and tend to attract non-target insects, disrupting ecosystems and increasing disease vector risks. These limitations highlight the need for more effective and sustainable mosquito control solutions. This study introduces a dual-output device that enhances fermentation-based systems by producing both CO2 for mosquito attraction and a fermented juice fertilizer for urban gardens. A Gradient Boosting algorithm was used to develop a molasses recommendation system, optimizing CO2 and fertilizer output. The system incorporates various sensors and an ESP32 microcontroller to monitor and control the fermentation process. Comparative testing with a UV trap was conducted in an urban garden in Sta. Rosa City, Laguna, Philippines. A one-tailed t-test yielded a t-value of 1.7889, indicating superior mosquito elimination performance. The Gradient Boosting model achieved an R² score of 93.23 % and a Mean Squared Error of 1002.6486, demonstrating strong predictive reliability. This study presents a sustainable approach to mosquito control, offering added agricultural benefits through organic fertilizer production.
