[Anopheles (Díptera: Culicidae) vectors of malaria in Puerto Carreño municipality, Vichada, Colombia].

INTRODUCTION

The study of the biological aspects of spp., strengthens the entomological surveillance.

OBJECTIVE

To determine biological aspects and behavior of adult mosquitoes in the urban area of Puerto Carreño municipality, Vichada, Colombia.

MATERIALS AND METHODS

Wild anophelines were collected landing on humans both indoors and outdoors between 18:00h and 06:00h for 50 min/h during two consecutive nights/month for eight months in the urban area of Puerto Carreño. The biting rate activity, the natural infection by and VK247 and VK210 using ELISA, and the annual entomological inoculation rate were determined for each species. The members of the Albitarsis complex were determined by amplificacion of the white gene by polymerase chain reaction.

RESULTS

In order of abundance the species found were i (n=1,166), (n=152), (n=59), F (n=25), (n=16), (n=3) and (n=2). showed two activity peaks between 21:00 to 22:00 and 05:00 to 06:00 hours outdoors and between 21:00 to 22:00 and 04:00 to 05:00 indoors. Natural infection of this species was found with VK210 and its annual entomological inoculation rate was 2. Natural infection of with was found, with an annual entomological inoculation rate of 5 and a peak biting activity between 18:00 to 19:00 hrs both indoors and outdoors.

CONCLUSION

Transmission of malaria in the urban area of Puerto Carreño, Vichada, can occur by and s. s.
