(Diptera: Culicidae) by using a "synthetic cohort" mark-release-recapture method. Mosquito age cohorts (1-2, 3-4, and 19-20 d) were released simultaneously in homes in rural Thai villages during dry and rainy seasons (2002). Significant age-dependent effects were detected during the dry and rainy seasons. More young than older mosquitoes were recaptured (1-4 versus 5-20 d). The best predictive fit for recaptures was obtained using a quadratic function of age. Our results provide the first field-based evidence for age-dependent Ae. aegypti mortality in which the death rate increases with advancing age and highlight the need for research on ecological and epidemiological aspects of this process. © 2008 Entomological Society of America.Mahidol UniversityAgricultural and Biological SciencesImmunology and MicrobiologyMedicineVeterinaryArticleSCOPUS10.1603/0022-2585(2008)45[307:ASOTDV]2.0.CO;2
