  1. Only the results from round 2 (17-30th October 2008) are presented. In all cases percentage mortality was ≤ 80%. Values are shown as percentage of total number of surviving or dead mosquitoes for each species. The total population represents the species distribution in the total population available for bioassay (see materials and methods for further details). The P value is the probability that the species distribution in the Survivors or Dead subset differs from the distribution in the total population.
