O objetivo do trabalho é medir as coberturas das atividades municipais de controle de Aedes aegypti e/ou Aedes albopictus, o casa-casa e o arrastäo, realizadas entre 1989 e 1995 na regiäo de Säo José do Rio Preto, Säo Paulo e avaliar a correlaçäo cruzada entre elas e os Indices de Breteau (IB). Para os municípios com até 50.000 imóveis as coberturas conjuntas das atividades casa-casa e arrastäo foram em sua maioria adequadas e as coberturas do casa-casa apresentaram correlaçäo cruzada negativa com os IB. Para município sede (maior que 50.000 imóveis) essas coberturas näo apresentaram correlaçäo com os IB. Em geral as coberturas foram inversamente proporcionais ao tamanho dos municípios. Para todas as faixas de tamanho de municípios, os arrastöes näo apresentaram correlaçäo com os IB, mostrando-se ineficazes

This study aims to describe and analyze the colonization of Aedes albopictus whose presence was detected in 1991 in the area of Sào José do Rio. Preto already colonized by the Aedes aegypti. Year and month of occurrence, counties, composition and location of larval samples, kinds of containers, average number of larvae an Breteau Index bare been analyzed from the information obtained in measurements of larval density by Superintendência de Controle de Endemias (SUCEN). The presence of Aedes albopictus was ascertained in 34 towns up to December 1994. The colonization of the area by the mosquito is still reduced showing some differences in relation to Aedes aegypti such as greater ratio outdoors, occupying container in different proportions. The average number of Aedes albopictus larvae has had influence of larvae of another species. It has showed a seasonal behavior similar to Aedes aegypti and it has moved from east to west direction.
