Interpretive Summary: Public health agencies and vector control organizations most often rely on battery-powered CDC light traps for surveillance of adult mosquitoes. These traps are often baited with carbon dioxide either supplied in the form of dry ice or as a gas from pressurized cylinders. Often dry ice is difficult to obtain or store. Buying or renting compressed gas cylinders and the regulators needed to control the release rate is expensive. In this paper we compare these traditional sources of carbon dioxide with an experimental product that releases carbon dioxide from sachets by mixing two granular products. While the product shows promise as an alternative source of carbon dioxide, more research needs to be done on its release technology to make its use practical.

Technical Abstract: CDC light traps and Mosquito Magnet® X (MMX) traps baited with dry ice, octenol, and a new formulation of CO2 (granular) were evaluated against mosquitoes in the field. The results showed that the MMX traps (68.6%) baited with dry ice collected more mosquitoes, compared to the CDC light traps (32.4%). The CDC traps baited with dry ice (64%) collected significantly more mosquitoes than traps baited with CO2 sachets (11%) or octenol (23%). The MMX traps baited with dry ice (85.5%) collected significantly more mosquitoes than traps baited with CO2 sachets (6.5%) or octenol (9%). The CDC traps baited with the formulations of normal and slow released CO2 sachets collected more mosquitoes than the formulation of fast released sachets. The CDC traps baited with fresh sachets and 24hr-exposed sachets collected significantly more mosquitoes than the traps baited with 48hr-exposed and 72hr- exposed sachets.
