Results of indoor collection of mosquitoes in health care unities in Santa Cruz do Capibaribe-PE.

<p>Number of positive sites out of 17 surveyed health care unities (HCU), and mean number of adult <i>Aedes aegypti</i> collected through indoor aspirations carried out fortnightly or monthly in HCU in Santa Cruz do Capibaribe-PE, from February 2009 to October 2011.</p

Smoothed spatial distribution of <i>Aedes</i> eggs at the high density period (May-June) in Ipojuca, Brazil, 2008–2011.

<p>Kernel maps based on the number of eggs deposed in one sentinel-ovitrap during one month. Data from a sentinel network of 75 ovitraps distributed over a 0.8 km² urban area. Mass suppression of eggs using 2700 control-ovitraps started in October 2009.</p

<i>Aedes</i> eggs collected in sentinel-ovitraps in Santa Cruz do Capibaribe (A) and Ipojuca MS (B).

<p>Median, and 75 and 25 percentiles for the quantitative series of collected eggs before (May/2008 to Sept/2009) and during (Oct/2009 to Oct/2011) the SMCP-<i>Aedes</i> control interventions.</p

Kernel smoothed egg distribution in Santa Cruz do Capibaribe-PE, Brasil, 2008 to 2011.

<p>Maps are based on eggs laid in 262 sentinel-ovitraps during low and high egg density seasons, before (May/2008 to Sept/2009) and during (Oct/2009 to Oct/2011) integrated control measures including mass-suppression of eggs using 5700 control-ovitraps, and larvivorous fishes added to around 7 thousand cisterns. The same scale was used for all compared kernel maps. For each survey, a self-scale kernel map was also constructed to highlight hotspots, as that shown on the bottom of the middle column, for July 2011.</p

<i>Aedes</i> eggs trapped in bimonthly cycles.

<p>Estimated amounts of eggs suppressed at every two months through continuous mass-trapping using approximately 2700 control-traps with Bti in the Municipal Seat of Ipojuca (A) and 5700 in Santa Cruz do Capibaribe (B), from October 2009 to October 2011.</p

Spatial distribution of <i>Aedes</i> eggs in Santa Cruz do Capibaribe-PE, Brazil, in 2009.

<p>Each kernel smoothed map of egg densities is based on the number of eggs deposited throughout one month in 262 sentinel-ovitraps placed over a 5.6 km² urban area in Santa Cruz do Capibaribe, at different times along 2009.</p
