Abstract

The timing of host-seeking behaviour was studied in two mosquito species, Anopheles annulipes sensu lato and Coquillettidia linealis at Mundic Creek, near the Upper River Murray in South Australia. Hourly sampling using carbon dioxide-baited traps revealed consistent patterns in the timing of host-seeking. Coquillettidia linealis displayed a very large peak in host-seeking activity at sunset, followed by a much reduced level throughout the night and a smaller peak at sunrise. Anopheles annulipes s.l. differed by displaying a significantly smaller peak at sunset, followed by higher amount of activity throughout the night compared with Cq. linealis. The two taxa, while both crepuscular and nocturnal, spread their host-seeking effort out differently throughout the night, indicating that they have different resource requirements.
