Based on the results, we believe that GAT is a promising candidate for mass-trapping intervention in urban settings, but a source reduction intervention should be made prior trap deployment. aegypti before egg-laying in different sizes and number of breading sites, whereas the oviposition activity occurred prior to recapture mosquitoes in the GAT. Our results confirmed the effectiveness of GAT for the capture of adult female Ae. Both traps showed similar results regarding to the parity status of recaptured mosquitoes. The GAT recaptured between 50–65% of the mosquitoes independent of the number and sizes of the breeding sites in the SOEs, whereas the BGS recaptured 60–82% of the females. The BGS trap was used here as a control (gold standard) trap to compare capture rates to those of the GAT. The number of eggs laid, and breeding productivity were also monitored when using different numbers and sizes of breeding sites. The parity status of the captured mosquitoes was also recorded. One hundred mosquitoes were released into the chambers, and recapture rates evaluated after 48h. Two identical large screened chambers inside of a SOE containing different numbers and sizes of artificial breeding sites were used to assess the trapping efficiency of the GAT. aegypti in semi-field conditions using simulated outdoor environments (SOE). Here the GAT was evaluated for the first time as a new tool to control Ae. albopictus populations using mass trapping techniques. aegypti (Gravid Aedes Trap-GAT) has been shown efficient for Aedes collection and suppress Ae. Adult traps, such as the BG-Sentinel (BGS), have been successfully used for mosquito surveillance and can also suppress vector populations. The mosquito Aedes aegypti is the main vector of arboviroses and current approaches to control this vector are not sufficiently effective.
