Evaluation of selected traps as tools for conducting surveillance for adult Aedes aegypti in Thailand.

The efficacy of the omnidirectional Fay-Prince trap (ODFP), the Centers for Disease Control Wilton trap (WT), and sticky lures (SL) were assessed as a means of evaluating population densities of adult Aedes aegypti in Thailand. Human landing/biting (L/B) collection was used as the reference method. The L/B collection method was significantly more effective at capturing Ae. aegypti than any of the other methods, with 84% (1,072/1,272), 8.5% (108/1,272), 7.2% (92/1,272) and 0% (0/1,272) of mosquitoes collected by L/B collection, ODFP, WT, and SL, respectively. Overall, none of the traps evaluated in this study was demonstrated to be an acceptable alternative to L/B collection for surveillance of adult Ae. aegypti in Thailand.
