MALARIA — Stages of development of the genera Anopheles, Culex, Aedes. Note the different positions assumed by the larvae of the three genera relative to the water surface. On the right: various aspects of the palps in males (♂) and females (♀) of the three genera.
Significant successes in the fight against malaria through the use of DDT are reported from all parts of the world. In Greece, the region of Europe most affected by malaria, the disease no longer constitutes a serious problem for health authorities. In Argentina, Bolivia, Brazil, Peru, Venezuela, and India, the curve of malaria cases and related mortality is declining. Even for the African continent, progress is being made.
