“…Containers found capable of accumulating water and becoming breeding containers for A. aegypti and or A. albopictus were classified into seven groups, according to Andrade et al (2019) and Soares-da-Silva et al ( 2012): Container Type CT1 -vases (plant pots and meal pots); CT2flasks (bottles, cans and plastics); CT3 -tires (all types of tires); CT4 -construction materials and car parts (materials used for construction and car parts); CT5 -storage (tank, barrel, filter, pot, bucket and drum); CT6 -fixed (drains, grease traps and wells); and CT7-others (all recipients that do not fit into the other categories).…”

Potential breeding containers for Aedes aegypti and Aedes albopictus mosquitoes are found in different environments, these places are considered by the National Dengue Control Program in Brazil as strategic points (SP), which have favorable conditions for the development of those insects. The aim of this study is to identify potential breeding containers for A. aegypti and A. albopictus at strategic points in the city of Codó, Maranhão. This study was conducted in five districts, one in each administrative area of the city. A survey of the types and quantity of existing strategic points in each neighborhood was carried out, and surveys of these properties were carried out to inspect the potential breeding containers, with the collection of the vectors’ number of immatures found at them. 125 properties were inspected of which 76.91% and 81.25% were vacant lots in the dry and rainy seasons, respectively. There was a difference between the median of the different strategic points (H = 21.96; p < 0.0001), For A. aegypti, there was no difference between the medians of number of immatures regarding the strategic points (H = 3.71; p = 0.28). The total number of immature A. albopictus was higher in vacant lots than in workshops (H = 9.41; p = 0.02, p < 0.05). 4,356 and 4,911 potential breeding containers were found in the dry and rainy seasons, respectively. Regarding the potential breeding containers, 7 (0.16%) and 47 (0.96%) were found with immature vectors, in the dry and rainy seasons, respectively. There were more positive containers in the rainy season for which there was a difference between the median of the number of mosquitoes per positive container (H = 15.66; p = 0.01), the number of immatures for the tires group was greater than Vases and Fixed groups (p < 0.05); the same result was observed in the analyses of the species in the separate form. The impressive number of potential breeding containers found in the SP in both seasons highlights the importance of developing control strategies for these vectors, with emphasis on places such as vacant lots, workshops, tire shops and junkyards, which are serving as dispersal urban sites of vectors.

“…aegypti and A. albopictus are characterized by their ability to easily colonize a variety of sites, even those with little accumulated water. Among the various sites, breeding containers kept by people in home environments stand out (Flaibani et al, 2020;Andrade et al, 2019;Soares-Pinheiro et al, 2017;Soares-da-Silva et al, 2012).…”
