The response of Ceratothripoides claratris, a newly identified pest on tomato, to colors was evaluated in a pesticide free tomato field. Traps were designed by color boards or clear polypropalene sheets coated with Beetle-Glue r. Tested colors were yellow, blue, white, light green, dark green, orange, purple, red and black. A clear polypropylene sheet covered with the insect adhesive was used as control. Blue and white cards attracted more C. claratris compared with other colors. Strongly UV - and blue light-reflecting colors and UV regions caught more C. claratris compared to the other colors. Hence intensity of blue and UV reflection appeared to be an important component of trap efficacy. A correlation existed between cumulative thrips counts and the leaf infestation level of tomato. The tomato plots without sticky traps showed higher leaf infestation by thrips.
