 en Embryonic development of Aedes aegypti check for this species in other resources (Diptera: Culicidae): influence of different constant temperatures
Farnesi, Luana Cristina; Martins, Ademir Jesus; Valle, Denise & Rezende, Gustavo Lazzaro

Abstract

Despite its vector importance little attention is given to Aedes aegypti check for this species in other resources 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°C; the maximum temperature limit is 35°C and the minimum one is below 12°C. Egg viability between 16-31°C was above 80%. The definition of physiological embryonic parameters at this temperature range corroborates Ae. aegypti presence on tropical and subtropical world regions.
