芸苔雌蝇的取食及着陆反应在实验室风洞中研究了不同形状的人造植物叶片对视觉信号的影响以及卷心菜植物气味的存在/不存在。树叶被涂上了镉黄色，在昏暗的红光下观察。雌性表现出对植物气味的定向飞行，但当气味与人造叶子一起出现时，着陆的频率明显更高。在三项选择测试中，叶片目标的形状（圆形、方形或三角形）对雌性的反应没有影响。然而，目标的大小确实影响了昆虫的反应：雌性更喜欢落在边长为5或10厘米的方形目标上，而不是落在边长为15厘米的最大目标上。目标的方向影响了昆虫的反应：雌性降落在垂直位置的目标上的频率明显高于水平位置的目标。
The approach and landing responses of femaleMamestra brassicae(L.) (Lepidoptera: Noctuidae) to visual cues from artificial plant leaves of different shapes and presence/absence of cabbage plant odour were investigated in a laboratory wind tunnel. The leaves were painted with cadmium yellow colour and observed under dim red light. Females showed oriented flight towards plant odours but landed significantly more often when the odour was presented with an artificial leaf. In three‐choice tests, the shape of the leaf targets (circle, square or triangle) did not influence the female response. However, the size of the target did influence the insect response: the females preferred landing on square targets with sides of 5 or 10 cm rather than on the largest target, with sides of 15 cm. The orientation of the target influenced the insects' response: females landed significantly more often on the target positioned vertically than horizontally.
