Abstract: In order to popularize the physical control technology for piercing-sucking pests in areca farm, effect of yellow sticky card to control pests under different hanging height and density were evaluated. The results indicated that the hanging position affected the trapping effect of sticky card. Areca tree with height of about 7 m was used as the test object, the effect of hanging on the crown of tree (in the petiole of the last 1~3 leaf from crown) was the best. The average number of thrips, leafhoppers, whiteflies and aphids trapped per sticky board was 7.84, 6.52, 11.84 and 6.76, respectively, while the effect of hanging in the middle (3~4 m from the ground) and lower part (1.5~2 m from the ground) of the trunk was poor. The average number of insects per sticky board in the lower position treatment was only 2.80, 1.76, 4.16 and 2.48, respectively. The results of different hanging density tests showed that the effects of 1 piece/plant, 1 piece/2 plant and 1 piece/3 plant were better. Taking the number of thrips trapped as an example, the average total number of insects trapped by the three treatments were 41.33, 42.33 and 37.67, respectively. Considering the trapping effect and use cost, the effect of 1 piece/3 plant was the best. In conclusion, when using yellow sticky insect board to control piercing-sucking insects in betel nut garden, the best control effect can be achieved by hanging 1 piece/3 plants under the crown of the tree.
