The behavior of yellow tea thrips, Scirtothrips dorsalis, on a reflective sheet (RS) was examined in mandarin orange and tea orchards in 1992 and 1993. The results are as follows : (1) The trap catch at ground level (GL) and at 1.5m above GL in the RS plot was lower than in the control plot. In the control plot, the trap catch at GL was lower than at 1.5m above GL. However, the trap catch at GL was almost equal to that at 1.5m above GL in the RS plot. (2) The trap catch at the end furthest from the tea field of the RS plot with malching for 2m next to a tea field was lower than the control plot. (3) More adults released in a small tree or on a stage in the center of the RS fell on the RS with mulching than on black-polyethylene mulching. (4) When adults were released from heights of 0.5-24cm above the RS (135×135cm) more fell on the RS from lower heights, and the number was almost equal to the control plot for a height of 50cm. (5) Adults released on the RS moved mainly by walking and did not fly continuously. Female adults released from shaded parts of the RS moved to unshaded parts, but not vice versa.
