- Description
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 nthropophily; 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.
Se evalu? la diversidad alfa de mosquitos y el riesgo a transmisi?n de pat?genos con base en variables de r?pida determinaci?n. El muestreo se realiz? en: zona urbana-rural, rural y rural-selv?tica de tres provincias. Veintidos especies fueron colectadas: 59 % son vectores comprobados; 45,5 % como adultos; 90,9 % en fases inmaduras; dos especies ?nicamente como adultos (9 %) y 12 especies ?nicamente como inmaduros (54,5 %). Cuatro especies fueron comunes a las tres provincias, 12 restringidas a una localidad y 9 en zona urbana. El 31,8 % mostraron antropof?lia. El 75 % de viviendas mantenian larvas de Culicidae, con ?ndice a?dico IC= 25 %, de recipientes IR= 5 %; Bretaeu= 37,5 %, con 8,56 recipientes/vivienda. Los resultados sugieren alta vulnerabilidad a la traslocaci?n y propagaci?n de pat?genos. Para la evaluaci?n deben considerarse cinco factores: presencia/abundancia relativa de vectores potenciales; porcentaje de antropof?lia; zona urbana: ?ndices a?dicos y socioecon?micos; presencia de especies selv?ticas y asociaci?n a viviendas en zonas de transici?n y el muestreo debe contemplar t?cnicas de colecta para ambas fases de desarrollo -inmaduros y adultos- para evitar una subestimaci?n de hasta un 50 % de la diversidad alfa con solo capturas para adultos.
