Fig 2. Trends in the number of positive ovitraps and egg counts between 2013 and 2018.

(A) Proportion of ovitraps (i.e. slats) that had eggs. (B) Average number of eggs per trap among the positive traps (i.e. slats). Traps that had not been set throughout the entire study were removed from the analysis. The error bars indicate the 95% confidence intervals (95% CI) around the average estimated using the generalised linear models. The large 95% CI's for Aedes koreicus are due to the low number of positive traps. "Aedes sp." denotes all counts associated with slats where the eggs were invasive Aedes species but could not be identified to species level.
