Pyrethroid Resistance Reduces the Efficacy of Space Sprays for Dengue Control on the Island of Martinique (Caribbean)
Figure 4
Mean number of females per trap placed outside houses before and after treatments.
This figure shows estimated densities of Ae. aegypti females in the 9 treated sites based on trap data (see Table 2 for data analysis). Four electric traps equipped with mosquito attractant were placed outside houses on terraces where they were protected from sun and rain. Traps were deployed at 11:00 AM and collected 24 hours later. Abundance (± SE) was estimated weekly starting 2 weeks before and ending 3 weeks after treatments (T).
