“…Residential characteristics are important factors in this process, as the development and breeding needs of this mosquito are generally contained in the home environment. 4,13,15 The present study analyzed characteristics that are not commonly considered when evaluating parameters that contribute to the density of this mosquito.…”

“…2 The absence of basic sanitation, irregular water supply and precarious housing conditions contribute to the formation of breeding sites for this mosquito species. 9 This species preferentially lays its eggs in septic tanks and gutters with stagnant water rich in organic matter, 4,21,22 which are common in urban environments of low quality.…”

“…4,13,15 According to Laporta et al, 16 the presence of vegetation surrounding the home may be a contributing factor toward the density of this mosquito, since the removal of vegetation from urban parks and consequent destruction of shelters results in the dispersion of the mosquito to other inhabited areas.…”

OBJECTIVE: Analyse how basic sanitation conditions, water supply and housing conditions affect the concentration of Culex quinquefasciatus METHODS:Populations of C. quinquefasciatus in 61 houses in the municipality of Olinda, PE, were monitored between October 2009 and October 2010. Observations were carried out in homes without the presence of preferred breeding sites in order to identify characteristics that may be aggravating factors for the development of the mosquito. Five aggravating factors were analysed: vegetation cover surrounding the home, number of residents/home, water storage, sewage drainage and water drainage. These characteristics were analysed in terms of presence or absence and as indicators of the degree of infestation, which was estimated through monitoring the concentration of eggs (oviposition traps -BR-OVT) and adults (CDC light traps). RESULTS:Sewage drainage to a rudimentary septic tank or to the open air was the most frequent aggravating factor in the homes (91.8%), although the presence of vegetation was the only characteristic that signifi cantly infl uenced the increase in the number of egg rafts (p = 0.02). The BR-OVT achieved positive results in 95.1% of the evaluations, with the presence of at least one egg raft per month. A total of 2,366 adults were caught, with a mosquito/ room/night ratio of 32.9. No signifi cant difference was found in the number of mosquitoes caught in the homes. CONCLUSIONS:Although the sanitation and water supply infl uence the population density of C. quinquefasciatus, residence features that are not usually considered in control measures can be aggravating factors in sustaining the mosquito population.

“…When separately applied, under this same concentration range, the compounds presented distinct attractancy, thus, determining an additive behavior, not synergistic. Barbosa et al (2007) demonstrated that high concentrations of synthetic oviposition pheromone (SOP) act as a repellent for oviposition in Cx. quinquefasciatus in laboratory.…”
