Starvation period and age affect the response of female Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) to odor and visual cues
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 24 h to an odor cue (1 μl of 10% p-anisaldehyde) was...

Zusammenfassung: | 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 24
h to an odor cue (1
μl 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 72
h, or of thrips of different ages (2–3 days or 10–13 days post-adult emergence) starved for 24
h, 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 4
h (76%) than satiated thrips (58.7%) or those starved for 1
h (62.7%,
