Aedes (Stegomyia) aegypti (L.) is a dipterous insect of the family Culicidae, which in Brazil is mainly responsible for the transmission of dengue virus (DENV), chikungunya fever virus, zika virus and yellow fever virus. The objective of this study was to evaluate in the laboratory a trap for capturing adults of mosquitoes Ae. Aegypti. The trap was made of PET bottles, had capacity for 1 litre, one of them being translucent, while the other was black. Tests were run in cages of two different sizes, each of them having 100 females and 100 males. As a first analysis, to compare the number of captured mosquitoes by sex, by type of trap, by size of cage used, as well as for the total number of eggs in each experiment as a whole was the Kruskal-Wallis tests were performed using a Level of significance of 95%. To analyze the frequency of catches of mosquitoes over time, survival analysis was performed by the Kaplan-Meier method. The curves were compared by the log-rank test, with a significant value of 95%. 823 mosquitoes were captured of the total number of mosquitoes used during all the experiments. There was no significant difference in the number of mosquitoes caught in light traps (Md = 38.5) and dark traps (Md = 63) (p = 0.344), as the trap had the same capture potential in medium cages and in small cages (p = 0.248). However, a significant difference in catch was observed for the sex, since females (Md = 72.5) were more captured than males (Md = 31.5) (p = 0.003). Survival analysis revealed that the dark traps captured faster than the translucent traps (p = 0.000), and that by comparing the sexes, the females were captured faster (p = 0.000). On the other hand, in the small cages females and males were captured with similar velocities (p = 0.852). In the average cages females were captured faster (p = 0.022). It is possible that the trap is more specific to females, and it can be used in low infestation areas, nonetheless field tests are needed for more concrete results. It is not a homemade trap, and its indiscriminate use may lead to it becoming a breeding site.
