Ecologia do Anopheles gambiae: pesquisas preliminares sôbre a viabilidade dos ovos que ficam fora da água

Within the possibilities offered by an emergency laboratory in Aracati, Ceará State, we studied the resistance of the eggs of Anopheles gambiae, maintained out of water under different conditions of temperature and humidity. The resistance observed was insufficient to justify special mosquito-control measures. The same results were obtained with larvae and pupae at low temperature. The analysis of the data concerning the egg resistance showed that hatching depends on stimuli.
