Changes in mosquito abundance as a function of the number of days with precipitation over 1, 5, 10, and 30 days. Data and error bars represent means and standard errors, respectively. Solid lines with gray shaded areas are polynomial regression lines with 95% confidence intervals, respectively. A third-order regression was best for 5- and 30-day periods; a fourth-order polynomial fit was best for 10-day period.
