Sustained, area-wide control of Aedes aegypti using CDC autocidal gravid ovitraps.
Bottom Line: We have shown that the Centers for Disease Control and Prevention (CDC) autocidal gravid ovitraps (AGO trap) reduced the Aedes aegypti population and prevented mosquito outbreaks in southern Puerto Rico.We monitored mosquitoes and weather every week in all four sites.Mosquito density in the former reference area decreased 79% and mosquito density in the new reference areas was 88% greater than in the intervention areas.

Mentions: There was an average reduction of 79% in the number of female Ae. aegypti per trap per week after placing the AGO intervention traps in IA-II (estimated means ± 95% confidence interval [CI]; before = 5.7; 5.0–6.6, after = 1.2; 1.0–1.4; Figure 2). The GLMM model showed significant effects of trap placement (before, after; F1, 2425 = 798.3, P < 0.001), week after trap servicing (F7, 2425 = 5.9, P < 0.001), rainfall (F1, 2425 = 16.3, P < 0.001), relative humidity (F1, 2425 = 47.2, P < 0.001), and temperature (F1, 2425 = 5.2, P < 0.05).
