  1. Notes: Shown are observed (Obs.) and expected (Exp.) mortality rates (numbers of dead larvae/pupae) in hot and cold spots with and without adult densities from closest BGST catch points fitted as a covariate. ABS ID numbers, area covered and relative risk (RR) with associated P-values are given. For space-time clusters, associated treatment day is also shown
