Rapid assessment of mosquito biodiversity (Diptera: Culicidae) and health enviromental risk in a mountain area belongs to Ecuadorian chocó

Abstract:

Alpha diversity of mosquitoes was evaluated and the risk of pathogen transmission based on variables of rapid determination. Sampling was conducted in: urban-rural, rural-rural and jungle areas of three provinces. A total of 22 species were collected: 59 % are proven vectors; 45.5 % were captured as adults, 90.9 % as immature phases; two species were captured as adults exclusively (9 %), and 12 species only as immature (54.5 %). Four species were common to all three provinces, 12 were restricted to one location, and 9 species in urban areas. 31.8 % showed anthropophily. 75 % of houses have Culicidae larvae with a Aedes index= 25 %, containers index= 5 %; Bretaeu index= 37.5 %, with 8.56 recipients/house. The results suggest high vulnerability to translocation and spread of pathogens. Five factors should consider: presence and relative abundance of potential vectors; percentage of anthropophily; urban area: Aedes and socioeconomic indices; presence of sylvan species and its association with homes in transition zones and sampling techniques must be include collection for both adults and immatures, which prevents underestimation of up to 50 % of alpha diversity if adults catch are used only.
