RESUMO:

Dengue is a viral disease whose causative agent is a virus transmitted by the Aedes aegypti mosquito, which uses water, not necessarily clean, to reproduce. This disease has become a serious public health problem, due to the difficulty in controlling the spread of this vector. Thus, alternative measures need to be studied to combat mosquito proliferation. This research aimed to characterize spatially and temporally the dynamics of dengue in the state of Mato Grosso, to identify whether three native fish species from urban streams were able to prey on A. aegypti larvae and to observe the presence of A. aegypti in urban streams. This is an epidemiological and descriptive study of the incidence rate and mortality from dengue, seeking to correlate with rainfall, Human Development Index (IDH), Demographic Density and the Urban Cleaning Sustainability Index (ISLU). Predation experiments were also carried out under laboratory conditions using three fish species (Moenkhausia dichroura, Astyanax asuncionensis and Aequidens plagiozanatus), in which A. aegypti larvae were offered to the species to identify whether there would be predation; and, finally, an active search for Aedes aegypti was carried out in three urban streams in the city of Cáceres. Dengue incidence did not show a significant relationship with population density (R²= 0.0025; p=0.56), but it was related to rainfall (R²=0.0019; p<0.05). The month of January had the highest incidence (83.27/100 thousand inhabitants). A. plagiozanatus reached 97.4% of predation, while M. diehroura and A. asuncionensis showed similar behavior, reaching 64.52% and 54.92% of predation, respectively. Five vectors were captured in adult form at the river mouth of the Sangradouro stream and its banks, as well as 57 larvae in stages I, II, III and IV of A. aegypti i. Dengue fever revealed epidemic peaks with high incidence rates in Mato Grosso, not showing any relationship with Demographic Density, but expressing a significant relationship with rainfall. The Brazilian native fish showed competence as predators of Aedes aegypti larvae. In the urban stream Sangradouro, adult larvae and mosquitoes of the vector that transmit dengue were found..
