The development of thermal fog generator for eliminating adult mosquitoes

Abstract

The thermal fog generator used for vector borne diseases control caused many problems including the difficulty to start engine, high temperature in combustion chamber, stop working of machine, easily damaged spare parts and long time to order. Those problems resulted in long time period of disease control and high maintenance budget. The purpose of this research is to develop low-cost standard thermal fog generator which serves all users’ needs. This is a research and development innovation which applied ADDIE model comprises of analysis, design, development, implement, and evaluation. The research reveals the developmental process of a practical thermal fog generator with the advantages as followed:  1) it met the standard criteria for thermal fog generator which includes standardized thermal pipe end 755 °C, flow rate 14.58 l/hour, droplet size 23.76 micron; 2) highly effective for kill adult mosquitoes which death rate of 100%; 3) Users are satisfied in high level ( x̄ =4.12±0.69. Besides these, the prominent properties are the external temperature of thermal fog generator is not too high while using, low fuel consumption and low production costs. Based on the major finding, it was highly recommended that this prototype thermal fog generator should be developed with standard manufacturing and evaluated for long term efficiency.
