The use of colored sticky traps is very common in population monitoring and pest management. The color trap attractiveness and capture rates of thrips vary according to species and trap color. Different color preferences of many thrips species have been studied by numerous scientists to enhance the attractiveness and sensitivity of various traps. In this study, the attraction of thrips by colored traps (blue, yellow and white) in the oak forests of Khoran and Kalan regions located in Eyvan city (Ilam Province, west of Iran) was investigated in 2018. The results showed that in both Khoran and Kalan regions, in all sampling months (except December), the blue sticky traps attracted significantly more thrips than other sticky traps. In the Khoran region, the highest number of attracted thrips with a value of 19.80 ±1.35 was related to blue traps and the May, and the lowest number of attracted thrips with a value of 1.01±0.44 was related to white and August. In addition, in the Kalan region, the highest and lowest number of thrips with a value of 15.80±1.35 and 1.80±0.3 were related to blue and yellow sticky traps in May and December, respectively. Generally, the results of this study showed that the efficiency of blue sticky traps was more than yellow and white traps. Overall, the use of blue sticky traps is appropriate for monitoring thrips on oak trees in the spring season.
