Abstract: [Objective] Thrips have become the main pests in mango trees. It is of great significance to use color sticky cards to monitor and control thrips in mango orchard, which can provide scientific basis for the control technology of thrips.[Method] The wavelength of reflection of color sticky cards was measured with spectrophotometric colorimeter, and the trapping effect of 10 different color sticky cards and the differences of hanging heights and hanging directions of color cards were compared.[Result] The results indicated that thrips in mango orchard significantly preferred blue color (466 nm),and the tapping effect was higher than other color trap cards, with an average amount of 154.6 head per card, follow by yellow (544 nm) and white (400 nm), with an average amount of 85.0 head per card and 51.8 head per card, respectively. There were also significant differences in the attraction effect with different hanging heights to thrips. The amount of thrips attracted by the trap cards with a height of 2 m was the largest (677.27 head per card), which was significantly higher than other treatments. However, the effect of different hanging directions on the attraction of thrips was not significant.[Conclusion] The blue card has the strongest trapping effect to mango thrips, and the hanging height is suggested to be 2 m.
