**Abstract**

The *Aedes aegypti* (Diptera: Culicidae) is dispersed throughout the Brazilian territory, being a transmitter of dengue and other arboviruses. This study analyzes the main breeding of *A. aegypti* in semi-arid tropical region. Samples have been collected for 12 months in the dry and rainy periods to watch the main breeding and characteristics of the proliferation sites. Most of the positive containers have been from the storage group (75.96%) found with immature forms mainly in the rainy season, with a predominance of containers having a height superior to 50 cm, protected from the sun and with organic matter. Theses breeding sites, where *A. aegypti* performs oviposition and survives in the dry season too.
