| Abstract: | Mark‐release‐recapture experiments with Aedes aegypti were performed using experimental huts equipped with entrance and exit traps to evaluate their movement patterns during a two‐year period in Thailand. Results indicate no significant differences in the patterns of movement between the two years of observation. Movement into the huts occurred during the early morning period (06:00‐11:00) with a peak at 07:00 in the summer and rainy season and 09:00 in the winter. In contrast, the exit pattern was observed during the late morning (09:00‐12:00) and early afternoon (12:00‐16:00), with a peak at 16:00 in the winter, 11:00 in the summer, and 14:00 in the rainy season. Multiple regression analysis indicated that movements of Ae. aegypti females into and out of the huts were impacted by humidity and temperature during the day. |
