Abstract
Background
Studies that improve and/or assess the ability of traps in vector detection, facilitate the control of diseases caused by these vectors.
Objective
The objective of this study was to compare four types of traps for A. aegypti capture and collection under field conditions, and to evaluate the influences of temperature and precipitation on the efficiency of these traps.
Method
Ovitraps (filter paper and palette), “mosquitéricas” and MosquiTRAP® were installed in 10 city blocks, which received on each face, one type of trap. Qualitative and quantitative entomological indices were calculated for all traps.
Results
The “mosquitéricas” trap had the lowest positivity index (3%). Only the IPAaegypti and IDAaegypti indices showed a positive relationship with temperature and precipitation, respectively. The ovitraps had up to 6.6 times more chances of positivity for A. aegypti when compared to MosquiTRAP®, with no significant difference between the filter paper and the palette substrates.
Conclusion
The ovitraps presented the best indices to be used in the surveillance of A. aegypti . The recommendation to use filter paper as a substrate for oviposition is imperative because of its lower cost, easier manufacturing, transport and storage, as well as better visibility of the deposited eggs.
