Influence of the spatial distribution of human hosts and large size containers on the dispersal of the mosquito Aedes aegypti within the first gonotrophic cycle

摘要: It is generally accepted that Aedes aegypti (L.) (Diptera: Culicidae) has a short dispersal capacity, and displacement can be influenced by the availability of oviposition sites in surroundings emergence or release sites. In present article, we observed influence spatial heterogeneity large containers human hosts on cumulative flight direction Ae. females during first gonotrophic cycle, testing hypothesis they aggregate resource-rich areas, i.e. where there are higher concentrations and/or humans per habitation. We analysed data from pupal surveys mark-release-recapture experiments (non-blood-fed were released) carried out two dengue endemic neighbourhoods Rio de Janeiro, Brazil: Tubiacanga (a suburb, with density 337 inhabitants/ha) Favela do Amorim slum, 901 inhabitants/ha). both host-seeking three different cohorts showed an overall non-uniform extensive their point within 1–2 days post-release. At 4–5 post-release, when many released would expected to gravid, most mosquitoes collected areas relatively containers/premise, independently residents/house, whereas Amorim, almost half captured resource-poorer areas. Although patterns varied between sites, distances travelled directions correlated hosts, more markedly than Amorim.
