a.Not calculated.
b.Larval densities increased over previous (pre-) application.
Average number of larvae (±SE) and pupae (±S.E.) per sampling point per sampling day and average number of adults (±S.E.) per emergence trap per day collected before (Pre-application) and after applying 1 ml/m2 (first application) and 2 ml/m2 (second application) of Aquatain. Percentage reduction after first and second application compared to pre-application and after second application compared to first application are given.
