Figure 2. Semi-field system for multi-choice assays of mosquito olfactory preference during host-seeking.

Figure 2.

(A) Aerial view of the screened mosquito flight cage arena with roof (green) surrounded by 8 one-person tents. Tents (2 per side) are connected to deliver olfactory stimuli via a ducting fan assembly to the flight cage arena.

(B) Side view of the mosquito flight cage arena.

(C) Schematic of the multi-choice olfactory preference assay. n = 200 mosquitoes per nightly trial.

(D) OGTA for use in the semi-field system. The ducting from each tent vents the target olfactory stimulus over a heated landing platform and mosquito landings are recorded.
