What are the ways to trap and kill agricultural pests?

In agricultural production, vegetables, fruit trees, grain and other pests will occur to varying degrees due to various reasons. Once pests occur and are not treated in time, growers will face reduced production or quality. What are the ways to trap agricultural pests?

1. Light trapping

Most pests have strong phototaxis, especially sensitive to ultraviolet rays, trapping effect is very good, can trap a variety of pests, such as lepidoptera, orthoptera, hemiptera, coleoptera and other pests. Black light traps are generally used during the adult pest occurrence period from May to September. A black light lamp is set up per mu. The lights are turned on at 9 o 'clock every night and turned off in the next morning. Most of the insects were attracted in the windless and sultry night.

2. Sweet and sour liquid trap

6 parts of sugar, 1 part of wine, 2-3 parts of vinegar and 10 parts of water. Add the right amount of pesticides. Can trap cutworm, Spodoptera litura, armyworm and so on. The prepared inducing liquid is placed in a pot, kept 3-5 cm deep, and placed in a pot per mu (the pot should be 30 cm higher than the crop) for 15 consecutive days.

3. Poison bait trapping

Wheat bran, cottonseed and bean cake are crushed to make bait, fried and fragrant. For every 5 kg bait, 0.15 kg of 30 times solution of 90% crystal trichlorfon is added, and proper amount of water is added and mixed evenly. Apply 1.5~2.5 kilograms per mu, can trap mole cricket, cutworm and other underground pests. 40 portions of banana peel or pineapple peel, 0.5 portion of 90% trichlorfon crystal and water are mixed into paste, 20 spots are set per mu, 25 grams are put in each spot, and pests such as fruit flies can be killed and killed. in that larva stage of cutworm, fresh young grass are collect, 50g of 90% crystal trichlorfon is dissolved in 1kg warm water, and then sprayed evenly on the young grass, and the poison bait is placed beside the victim plants and scattered among the rows of crops in the evening to trap and kill. Dig 30~60 cm square earth pit in the field head, put horse dung inside, sprinkle a little trichlorfon powder under dung, but trap mole cricket. Can also be set up in the field water tank, pot drops a small amount of sesame oil and pesticides, but also has a certain role in trapping.

4, willow branches trapped

Will be half a meter or so half withered willow branches, elm branches, every 10 tied into a bundle, dipped in pesticides, one end tied stick inserted into the ground, inserted 5--10 bundles per mu. Can trap armyworm, Spodoptera litura and other adults.

5. Rice grass lures eggs

Adult armyworm has yellowtaxis and likes to lay eggs on yellow grass. Rice grass or millet grass can be tied into a thick straw handle, strung with a small stick (70~80 cm long), inserted into the wheat field (10~20 per mu), lured moths concentrated on the straw handle to lay eggs, 5~7 days for new straw handle, and the old straw handle will be recovered and burned. Insert 2 - 3 times continuously.

6. Yellow plate trapping

Cardboard, or fiberboard, etc., about 10 cm long, 2-3 cm wide, painted yellow with paint, then coated with a layer of sticky oil, about 20 pieces per mu, placed in the field and plant height, can effectively trap whitefly, aphid, leaf miner, etc. When the worm sticks to the plate, reapply the sticky oil in time, generally reapply it in about 7 days.
