Schematic representation of the behavior bioassay chamber used to test the attraction of <i>A</i>. <i>glabripennis</i> females and males to visual and/or olfactory cues.

<p>(A) host plants and non-host plants cue chambers and test arena; 1, air sampler; 2, glass column with distilled water; 3, glass filter with activated charcoal; 4, one of storage chambers; 5, gas flow meter; 6, air access port of teflon tube; 7, I-tube arena; 8, air exit port of teflon tube; 9, gas flow meter; 10, air sampler, 11, access/exit port of test insects; 12, concave bracing column; the hollow arrows indicate the air flow (300 mL/min) generated with an atmospheric sampling instrument. The storage chambers that provided visual (B), olfactory (C), and visual + olfactory (D) cues of host plants, non-host plants and the blank control for <i>A</i>. <i>glabripennis</i> females and males.
