A survey was conducted in Maharashtra State, India, during 1971-73 on the distribution and relative prevalence of Aedes aegypti (L.) during dry (December-May) and wet (June-November) seasons. The single larva survey and adult collection methods were used. Data were also collected on larval habitats in different regions. The mosquito was present in 49 of the 105 towns visited. The distribution of A. aegypti was widespread; the prevalence was greater in eastern parts (Marathwada and Vidarbha regions) than in western parts (coastal and central regions). Comparison of the results of this survey with those of earlier ones showed that the distribution of A. aegypti was increasing in size. The possible recent mode of spread and the current distribution pattern are discussed. There were considerable differences in the nature and number of larval habitats in each region. Metal containers outnumbered other types of containers in coastal and central regions, whereas 'mud, brick, cement and stone' containers did so in Marathwada and Vidarbha regions. Container indices rose in proportion to the number of potential breeding containers available in Marathwada and Vidarbha regions but not in the other 2 regions. These findings are discussed in relation to the water-storage habits of the people in the regions concerned.
