A Simple CO₂ Generating System Incorporated with CDC Light Trap for Sampling Mosquito Vectors.

ABSTRACT: Traps for capturing mosquitoes and other blood-feeding arthropods are often baited with carbon dioxide (CO₂) as an attractant. Dry ice is popularly used as a CO₂ source due to its high efficiency and ease of use. However, dry ice can be difficult to obtain in many rural and remote areas. The objective of this study was to develop a simple and inexpensive method that could continuously generate CO₂ overnight (about 10 h) while being used with CDC light traps for sampling adult mosquitoes. In principle, CO₂ was produced from the reaction between hydrochloric acid (HCl) (12% w/w) and limestone powder (mainly composed of calcium carbonate, CaCO₃). In laboratory experiments, an average of 256 mL of CO₂ was produced
