Schematic diagram of the trap positions and mosquito release points within the semi-field system.

<p>Set ups for experiments 1, 2 and 3, are shown in figure panels A, B and C, respectively. Trap positions are shown in circles, and mosquito release points in triangles. In all experiments, the treatment being tested was rotated between the test locations nightly.</p

Results of pair-wise post hoc comparison using Tukey’s honestly significance tests (Tukey’s HSD).

<p>Howing similarities and differences between number of mosquitoes caught in traps baited with different lures (Panel A) and number of mosquitoes caught in traps baited with different lures dispensed from different media (Panel B).</p

Illustration of design and functionality of: (A) BG-Sentinel and (B) BG-Malaria.

<p>IF = Intake funnel; CB = Catch Bag; F = Fan; G = Gauze Cover; T = Tube; RC = Recipient of CO₂; OB = Odour Bait. Arrows indicate the direction of the airflow. Adapted from Kröckel <i>et al</i>., (2006) and Gama <i>et al</i>., (2013).</p

Devices used for dispensing mosquito attractants.

<p>Panels A and B show attractants infused inside microcapsules supplied by Biogents Company encased in a plastic sachet (BG-Sachet) and plastic cartridge (BG-Cartridge), respectively. Panel C shows a batch of nylon strips, each soaked in solution of a different constituent of the synthetic attractant [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0186696#pone.0186696.ref033" target="_blank">33</a>].</p

Distribution and median number of <i>Anopheles arabiensis</i> recaptured per night using different trapping methods in the semi-field system.

<p>BGM = BG-Malaria trap; BGS = BG-Sentinel trap.</p
