ABUNDANCE AND SPATIAL-DISTRIBUTION OF MOSQUITOS AT LAKE BULLAWARRA, QUEENSLAND (DIPTERA, CULICIDAE)

During 1976-78, seven trips were made to Lake Bullawarra and 29,118 mo squitoes comprising 19 species were collected. Vertical and horizontal distribution of mosquitoes was investigated using chicken baited trap s at three different heights (0, 6 and 12 m) and three horizontal dist ances from shore (0, 31 and 57 m). Culex quinquefasciatus was the most localised species, being captured at ground level and close to the la ke shore. Culex annulirostris, Anopheles annulipes s.l. and Aedes eids voldensis were also more common close to the ground, but no significan t differences in the distribution of these species were found away fro m the lake edge. These species were also the most common in the majori ty of the other collections.
