Small plot experiments were conducted in 2007, 2008 and 2009 in which acaricides were applied to early and late-planted staked tomatoes based on threshold levels ranging from 0 to 50 mites per leaflet, with a non-treated control included. Vine ripe fruit were harvested at weekly intervals from all plots, and fruit were weighed and graded for size and quality. A partial budget analysis was conducted to compare net profitability among treatments. Results from 2007 to 2008 showed that total and marketable yield was higher in plots with low versus high densities of T. urticae, and that yield differences were mostly due to number of fruit harvested rather than size of fruit. In 2009 there were no differences in yields among treatments. Gold fleck caused by T. urticae feeding directly on the fruit was another factor that influenced marketability, with more fruit affected and a higher percentage of surface area affected in higher densities versus lower densities of T. urticae. Net profitability varied considerably among planting dates and years, but an action threshold level to avoid yield losses by T. urticae injury on staked tomatoes appeared to be about eight mites per leaflet on a second or third recently expanded leaf.}, journal={Crop Protection}, publisher={Elsevier BV}, author={Meck, Elijah D. and Kennedy, George G. and Walgenbach, James F.}, year={2013}, month={Oct}, pages={84–90} }

Field observations suggested that T. urticae feeding on fruit may have resulted in discoloration known as gold fleck. A series of experiments were undertaken in the field and laboratory to evaluate T. urticae feeding as a cause of gold fleck on the fruit. Field experiments showed that, as cumulative mite days increased, so did the percentage of fruit affected by gold fleck. Results from laboratory experiments showed that T. urticae feeding on tomato fruit did cause gold fleck. This study clearly demonstrated that T. urticae can damage tomato fruit directly in the form of gold fleck, which may impact marketability of that fruit.}, journal={CROP PROTECTION}, author={Meck, Elijah D. and Walgenbach, James F. and Kennedy, George G.}, year={2012}, month={Dec}, pages={24–29} }
