Table 5

Average Aedes  aegypti pupal productivity/demographic profile according to the category of larval container habitats in São Sebastião, State of São Paulo, Brazil (October 2002–April 2003, and October 2003–April 2004). Note that container categories are sorted according to decreasing frequency of larval positivity as in Table 4. The “Other” category of removable containers shown in Table 4 was excluded from this table as it only represented 0.3% of all positive containers.
