This study details the use of emergence traps with sticky adhesive to captu
re adult mosquitoes emerging from brackish water pools located in almost im
penetrable swamp oak and tea-tree forests in Maroochy Shire, south-eastern
Queensland. Twenty emergence traps were set weekly for 12 weeks between Mar
ch and June 1998. during which time a total of 825 adult mosquitoes were co
llected. Aenes procax (Skuse) (55%) was the most abundant species, followed
by Verrallina funerea (Theobald) (16%) and Culex halifaxii Theobald (9%).
Emergence of Ve.. funerea was greatest after tidal inundation of pools with
brackish water, whereas Ae. procax emerged in greatest numbers following h
eavy rainfall. As there are significant areas of swamp oak and tea-tree for
est in Maroochy Shire and an increasing pressure for urbanisation in adjace
nt areas, the aerial application of persistent s-methoprene formulations is
considered the most appropriate option for control.
