We compared 6 adult mosquito traps for effectiveness in collecting Aedes albopictus from suburban backyards with the goal of finding a more suitable surveillance replacement for the Centers for Disease Control and Prevention CDC light trap. Trap selection included 2 commercial propane traps Mosquito MagnetTM Professional trap and Mosquito Magnet Liberty trap, 2 Aedes-specific traps Fay-Prince Omnidirectional trap and Wilton trap, 1 experimental trap Mosquito Magnet-X trap, and a standard surveillance CDC light trap that served as a control. Traps that did not generate carbon dioxide were provided with bottled CO2 at a flow rate of 500 mlmin. Those traps designed for use with chemical attractants Mosquito Magnet traps were baited with LurexTM L-lactic acid and octenol 1-octen-3-ol commercial baits, known attractants to Ae. albopictus. Three repetitions of a 6 X 6 Latin square test yielded a total of 37,237 mosquitoes, of which 5,280 14.2 were Ae. albopictus. Significantly more P 0.05 Ae. albopictus were collected from the experimental and commercial traps 4,2445,280 80.3 than from the CDC light trap and Aedes-specific traps. The Mosquito Magnet Liberty collected the most Ae. albopictus 1,591, accounting for 30.1 of the total take, followed closely by the Mosquito Magnet-X 1,468 and the Mosquito Magnet Pro 1,185. The omnidirectional Fay-Prince trap performed better than the CDC or Wilton trap. Twenty-seven mosquito species were collected during these trials, 9 species in large enough numbers for meaningful analysis. Aedes albopictus was the second most common mosquito trapped. The results of these trials indicate that propane-powered commercial traps would serve as useful substitutes in lieu of CDC traps in Ae. albopictus surveillance efforts. Trap features advantageous for collecting Ae. albopictus and other mosquito species are discussed.
