The effects of starvation or age on the walking or flying response of female Frankliniella occidentalis to visual and/or odor cues in two types of olfactometer were examined in the laboratory. The response of walking thrips starved for 0, 1, 4, or 24h to an odor cue (1microl of 10% p-anisaldehyde) was examined in a Y-tube olfactometer. The take-off and landing response of thrips (unknown age) starved for 0, 1, 4, 24, 48 or 72h, or of thrips of different ages (2-3 days or 10-13 days post-adult emergence) starved for 24h, to a visual cue (98 cm(2) yellow sticky trap) and/or an odor cue (0.5 or 1.0 ml p-anisaldehyde) was examined in a wind tunnel. More thrips walked up the odor-laden arm in the Y-tube when starved for at least 4h (76%) than satiated thrips (58.7%) or those starved for 1h (62.7%, P<0.05). In the wind tunnel experiments the percentage of thrips to fly or land on the sticky trap increased between satiated thrips (7.3% to fly, 3.3% on trap) and those starved for 4h (81.2% to fly, 29% on trap) and decreased between thrips starved for 48 (74.5% to fly, 23% on trap) and 72 h (56.5% to fly, 15.5% on trap, P<0.05). Fewer younger thrips (38.8%) landed on a sticky trap containing a yellow visual cue of, those that flew, than older thrips (70.4%, P<0.05), although a similar percentage of thrips flew regardless of age or type of cue present in the wind tunnel (average 44%, P>0.05).
在实验室中，研究了饥饿或年龄对西花蓟马雌虫在两种嗅觉仪中对视觉和/或气味线索的行走或飞行反应的影响。在Y型嗅觉仪中检测了饥饿0、1、4或24小时的行走蓟马对气味线索（1微升10%对甲氧基苯甲醛）的反应。在风洞中检测了饥饿0、1、4、24、48或72小时的蓟马（年龄未知），或不同年龄（成虫羽化后2 - 3天或10 - 13天）饥饿24小时的蓟马对视觉线索（98平方厘米黄色粘虫板）和/或气味线索（0.5或1.0毫升对甲氧基苯甲醛）的起飞和着陆反应。在Y型管中，饥饿至少4小时的蓟马（76%）比饱腹蓟马（58.7%）或饥饿1小时的蓟马（62.7%，P<0.05）更多地沿着充满气味的臂行走。在风洞实验中，饱腹蓟马（7.3%起飞，3.3%落在粘虫板上）和饥饿4小时的蓟马（81.2%起飞，29%落在粘虫板上）之间，落在粘虫板上飞行的蓟马百分比增加；而饥饿48小时（74.5%起飞，23%落在粘虫板上）和72小时的蓟马（56.5%起飞，15.5%落在粘虫板上，P<0.05）之间，该百分比下降。尽管在风洞中，无论年龄或存在的线索类型如何，起飞的蓟马百分比相似（平均44%，P>0.05），但落在含有黄色视觉线索的粘虫板上的较年轻蓟马（38.8%）比年长蓟马（70.4%，P<0.05）少。
