Using insecticidal board to treat insect pests is environmentally friendly and economical and worth recommending. How to properly hang the sticky board to make it more effective? First of all, the number of sticky board installations should be determined based on the number of major pests to be controlled. If the number is too small, the expected control effect cannot be achieved, but it is not necessary to set the number too large. Such as the prevention of greenhouse whitefly, tobacco whitefly, set 30 to 40 pieces of mucilage board per acre can. Second, the location of the yellow stick board is not suitable, which will result in a significant reduction in the effectiveness of the stickworm. Taking the main control insect pest B. tabaci as an example, B. tabaci migration is relatively poor, so the hanging height of the yellow armyworm board should be kept slightly flat or 10 cm higher than the growth point at the bottom of the board. And as the plants continue to grow taller and timely adjust the height of the suspended board of stickies board. Suspended correctly, these yellow stick boards can be used as they are. In the tomato plot, the adjacent four stick board was divided into two groups with different heights. The height of one group of sticky planks was set to be higher than the top growth point of the tomato within 10 cm, which was relatively poor for the migration. Whitefly pests; the height of the other sticky board is set to be 30 to 40 cm higher than the top growth point of the tomato, in order to target the more aggressive aphids and other pests.
