The efficiency of sticky colored traps and colored water traps in thrips (Insecta: Thys.) attraction in the legumes fields of Ilam province

In this study, the efficiency of colored traps (sticky colored and colored water traps) in thrips attraction in the legumes of Ilam province was investigated. The experiment was conducted in a completely randomized block design with four treatments (yellow, blue, white and green colors) and twelve replicates during two years. On average, the highest number of thrips in chickpea and lentil fields in the year 2019 were 12.03±0.17 and 15.79±0.14 and also in the year 2018 were 9.88±0.15 and 13.45±0.21 for blue sticky traps, respectively.  Also the results of colored water traps showed that in both years, the highest average number of thrips for chickpea and lentil fields was related to blue water trap; so that the highest average number of thrips in chickpea and lentil fields in the year 2019 were 5.29±0.13 and 7.07±0.19 and in the year 2018 was 5.22±0.13 and 5.97±0.17, respectively. Also, according to the data, the highest rate of thrips attraction to colored sticky traps and colored water traps in chickpea and lentil fields was duting the flowering stage of host plants. Overall, the results showed that the efficiency of colored sticky traps was higher than colored water traps. Also, the use of blue and yellow colored traps is appropriate in the management control of thrips.
