Embryonic development of Aedes aegypti (Diptera: Culicidae): influence of different constant temperatures.
Despite its vector importance little attention is given to Aedes aegypti embryonic development. In this study, temperature influence on time course of Ae. aegypti larvae hatching and egg viability were evaluated. The dormancy state at the end of embryogenesis could be interrupted with a proper stimulus. Temperatures tested ranged between 12-36 degrees C; the maximum temperature limit is 35 degrees C and the minimum one is below 12 degrees C. Egg viability between 16-31 degrees C was above 80%. The definition of physiological embryonic parameters at this temperature range corroborates Ae. aegypti presence on tropical and subtropical world regions.
