1, the use effect is the same, but the yellow board attracts more insects and the blue board is more targeted. 2. The yellow board is mainly used to trap and kill all kinds of flies and black flies, such as Bemisia tabaci, whitefly, aphid, moth, yellow striped flea beetle and so on. 3. The blue board mainly traps thrips and various flies, such as liriomyza sativae. 4. Different armyworms can be reasonably selected according to the species characteristics of pests in the planting area.
1. What is the difference between armyworm blue and yellow?
1, armyworm is a low-cost green prevention and control method, which is widely used in agriculture.
2. Stick insects have other colors, such as yellow, blue and red. The yellow board and blue board of armyworm have the same effect, but because of the different colors, they attract different insects. The yellow board attracts more insects, and the blue board is more targeted to kill insects.
3. The yellow board can trap and kill all kinds of flies and black flies, such as Bemisia tabaci, Bemisia tabaci, aphids, moths, Lepidoptera flavipectus, Liriomyza sativae, thrips, Liriomyza sativae, Bemisia melanogaster, tea leafhopper and various winged pests.
4. The function of blue board is to trap and kill thrips and all kinds of flies, such as liriomyza sativae, which is characterized by targeted action and concentrated trapping and killing.
5. Because the yellow board and blue board of armyworm have different trapping and killing effects on pests, different armyworms should be selected reasonably according to the characteristics of pests in planting areas during use.
6. armyworm is a physical trapping method, not a chemical agent, and it is safe for people. When in use, it can be simply hung, which is simpler and clearer.
Second, the use of stick insects.
1. In the greenhouse, one end of the wire and rope is tied to the scaffold, and the other end is tied to the reserved hole of the insect catching board, which can be hung vertically.
2. When it is used in the open air, the bamboo pole or wooden stick can be inserted into the ground, and then the insect trap board can be tied to the bamboo pole or wooden stick with a bandage and hung at a distance of 15-20cm from the surface of the crop, and adjusted with the growth height of the crop.
3. 30-40 pieces can be hung per mu of farmland, which can be adjusted according to the actual population density, and the hanging effect in the east-west direction is better. Can be used with special bait, about 30 pieces can be used per mu.
4, the color of the insect trap board is more accurate, the trapping and killing are more effective, the outdoor hanging time is long, and various modifiers are added, which has the advantages of good viscosity and no flowing at high temperature.
