Insect nets and sticky insect boards are very suitable for application in vegetable greenhouses. Insect nets can block the migration of pests into greenhouses. Sticky insect boards can trap and reduce the density of insects in the greenhouse. The insect nets and sticky insect boards can be used together, and the control effect is best.
Insect-resistant nets are mainly used to cover and cover the vents and doorways of greenhouses, and to block external pests from entering the shed to reduce the occurrence of pests and diseases. The lepidopteran adults such as Pieris rapae and Spodoptera litura are selected from 20 to 30 mesh insect nets, and 40 to 60 mesh insect nets are selected for small insects such as B. tabaci and B.
The wormwood board traps and selects the appropriate color of the wormwood board according to the type of pests that are trapped. The yellow wormwood board mainly kills whitefly, aphids, spider mites, spotted fly, etc., and the blue board mainly traps thrips and various flies. The hanging height of the wormwood board is about 20 cm higher than the top of the plant, and 25~30 pieces of sticky worm board of 25 cm×30 cm size are suspended per acre. If the growth is too high, the plant rows can be hung. The suspension time should be carried out during the seedling period of the vegetables and in the early stage of planting without pests to ensure the control effect.
