As measured by the criteria of ability to disperse and to adapt to varying environments, Aedes aegypti must be reckoned as a distinctly successful species. The best present evidence is that the species originated in Africa and spread from there to most of the tropical and subtropical areas of the world, most often with the unknowing assistance of man. Once having become established in a favorable area it may be eliminated only with considerable expenditures of time, money and human ingenuity. That eradication is possible, given these elements, is amply demonstrated by the campaigns conducted in tropical America under the aegis of the Pan American Health Bureau. However, difficulty has been encountered even in that generally successful program due to the emergence of insecticide resistant strains of aegypti in recent years.
