Resumen:
Water holding tree holes are main larval habitats for many pathogen vectors, especiallymosquitoes (Diptera: Culicidae). Along three years, the diversity and composition ofmosquito species in tree holes of two neighbouring but completely differentenvironments, a city and its adjacent forest, were compared using generalized linearmixed models, PERMANOVA, SIMPER and species association indexes. The city area(Northwest Argentina) is highly relevant epidemiologically due to the presence ofAedes aegypti L. (main dengue vector) and occurrence of dengue outbreaks; theYungas rainforests are highly biologically diverse. In total 7 mosquito species wererecorded, in descending order of abundance: Ae. aegypti, Haemagogus spegazziniiBrèthes, Sabethes purpureus (Theobald), Toxorhynchites guadaloupensis Dyar andKnab, Aedes terrens Walker, Haemagogus leucocelaenus Dyar & Shannon andSabethes petrocchiae (Shannon and Del Ponte). The 7 mosquito species wererecorded in both city sites and forested areas; however, their mosquito communitiessignificantly diverged because of marked differences in the frequency and relativeabundance of some species: Tx. guadeloupensis and Ae. aegypti were significantlymore abundant in forest and urban areas, respectively. Positive significant associationswere detected between Ae. aegypti, Hg. spegazzini and Hg. leucocelaenus. Thecombined presence of Ae. aegypti, Haemagogus and Sabethes in the area alsohighlight a potential risk of yellow fever epidemics. Overall results show animpoverished tree hole mosquito fauna in urban environments, reflecting negativeeffects of urbanization on mosquito diversity.
