在一个圆柱形的黑盒子和一个Y型管嗅觉仪的行为反应的Frankliniella occurentalis Pergande（Thysanoptera：蓟马科）的视觉和嗅觉线索进行了评估。在多项选择试验中，西花蓟马对圆形的偏好程度高于其他5种几何形状（矩形、三角形、倒三角形、菱形和仿花瓣的改良圆形）。在成对选择试验中，蓟马更喜欢黄色的人造花形状的几何图案测试。花蓟马在人造花上的停留时间是在几何图案上的4倍左右。较高数量的蓟马对茴香醛和人造花的组合相比，只有嗅觉或视觉提示的手臂。这些结果表明，形状是一个重要的线索F。[咒语]
Behavioral responses of Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) to visual and olfactory cues were assessed in a cylindrical black box and a Y-tube olfactometer. Frankliniella occidentalis preferred circular shapes to other five geometrical patterns (rectangle, triangle, inverted triangle, diamond, and modified circle imitating flower petals) in multiple choice tests. In pair wise choice tests, the thrips preferred the yellow artificial flower shape to the geometrical patterns tested. Frankliniella occidentalis stayed on the artificial flower about four times longer than on the geometrical patterns. Higher numbers of thrips responded to a combination of p-anisaldehyde and artificial flower compared to the arm with only the olfactory or the visual cue. These results suggest that shape is an important cue for F. occidentalis.
