Abstract In this study, the efficiency of different traps including window trap and colored pan traps (white, yellow, red, purple and blue ones) to capture members of the order Coleoptera was assessed in the two rangeland and farmland habitats of the Saral Agricultural Station of Kordestan province. During the study, a total of 18509 individuals from 19 families of the Coleoptera were collected using the different traps. The results showed that the rarefaction curve of window trap had the most coordination and estimation with total rarefaction curve. There was significant difference (α=5%) among the traps in value of Shannon-Wiener index (P=0, df=5, F=37.07) and Simpson index (P=0, df=5, F=10.87) in rangeland area. While window trap had higher mean Shannon- Wiener and Simpson indexes (0.9±0.06 Bit and 5.8±1.1 respectively) than colored pan traps. In farmland area, there also was significant difference (α=5%) among the traps in value of Shannon-Wiener (P=0, df=5, F=16.84) and Simpson indexes (P=0, df=5, F=9.18) in, while window trap and white pan traps had highest mean Shannon- Wiener index (0.9±0.02 Bit and 0.8±0.08 Bit respectively) and Simpson index (6.1±0.5 and 5.6±1.5 respectively).
