The damage to grape (cultivar : Delaware) caused by Scirtothrips dorsalis HOOD was investigated in vineyards with different thrips densities in 1991-1993. There were significant positive correlations between the density of S. dorsalis per fruit cluster and the damage to fruit clusters during the period from mid-June to mid-July. The tolerable pest density per fruit cluster was estimated at 0.8 in mid-June, 2.0 in late June, 3.5 in early July and 4.0 in mid-June assuming the fruit cluster damage index to be 20. There were also significant positive correlations between the number of S. dorsalis adults caught by yellow sticky traps and the damage to fruit clusters from mid-June to mid-July. The tolerable adult catch per trap per day was estimated at 10.1 in mid-June, 10.0 in late June, 23.0 in early July and 71.8 in mid-July. The latter data can be used as the control threshold for this thrips.
