Introduction:

Tropical urban areas favor the presence of Aedes aegypti in the American continent. Other mosquitoes can share the same geographic distribution with this mosquito, which justifies that they must be monitored.

Objective:

It is to know the dynamics of oviposition of A. aegypti, evaluate its gonadotrophic state and determine taxonomically the presence of other culicidae in the metropolitan area of Bucaramanga.

Methodology:

Oviposition traps (N = 960) were baited with hay infusion (10%) for one year in four locations (Norte, Girón, Piedecuesta and Floridablanca). The ovitraps were kept for five days indoors and outdoors, while larvae were collected in plants such as bromeliads and water reservoirs from each collecting site. In the month of May 2014, were captured with an electric aspirator and traps to catch females of A. aegypti and Culex quinquefasciatus to which were estimated their gonadotrophic state. Environmental data such as precipitation and temperature were correlated with the collected eggs and their oviposition indices.

Results:

25,254 eggs of A. aegypti were obtained (39.1% Girón, 36.8% Bucaramanga, 15.2% Floridablanca and 8.9% Piedecuesta). In general, oviposition rates were higher outdoors. As for the gonotrophic state, it was detected that females of A. aegypti can have for over two gonadotrophs cycles. In the active catch outdoors were found Culex spp., Culex quinquefasciatus, Limatus durhamii, Toxorhynchites spp and Wyeomyia davisi.

Conclusion:

A. aegypti was present in all localities and other mosquitoes are reported in the metropolitan area.
