Figure 1.
Spatial distribution of mosquito egg for Ipojuca and Santa Cruz do Capibaribe-PE, Brazil, in May 2008.
The Kernel maps showing smoothed egg densities are based on the number of eggs deposited in each sentinel-ovitrap during one month. Data from the sentinel network encompassing 262 ovitraps distributed over a 5.6 km2 urban area in Santa Cruz do Capibaribe and 75 ovitraps over a 0.8 km2 urban area of Ipojuca municipal seat.

Figure 2.
Spatial distribution of Aedes eggs in Santa Cruz do Capibaribe-PE, Brazil, in 2009.
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.

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

Aedes eggs trapped in bimonthly cycles.
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.

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-Aedes control interventions.
Figure 6.
Kernel smoothed egg distribution in Santa Cruz do Capibaribe-PE, Brasil, 2008 to 2011.
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.

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