| Abstract: | Despite the importance of the mosquito Aedes aegypti in thetransmission of arboviruses, such as yellow fever, Chikungunya fever and denguefever, some aspects of their behaviour remain unknown. In the present study, theoviposition behaviour of Ae. aegypti females that were exposed todifferent densities of breeding sites (2, 4, 8 and 16) was evaluated in laboratoryand semi-field conditions. The number of breeding sites that were used wasproportional to the number available, but tended towards stabilisation. Females usedfour-six breeding sites on average, with a maximum of 11. A high percentage of eggswas observed in the water, along with the presence of a breeding site termed“favourite”, which received at least 40% of the eggs. The results are discussed inecological, evolutionary and epidemiological approaches. |
