Table 1.

Correction coefficients to calculate absolute Ae. aegypti density for each of the three metrics (adult, female and male) derived from fitting a simple linear regression to total catch data (y) and the number collected during the first 10-min sampling round (x), and following the equation y = a + bx, where a is the intercept. The top panel shows the fit to all data and the bottom panel shows the fit to the dataset excluding the extreme values shown in Fig. 4
