7 methods commonly used to trap pests

In the integrated pest control technology system for fruits, vegetables and grains, the trapping technology is a component that cannot be ignored and plays an important role in production. It is not only economical, safe and simple,SWAN insect killer supplier but also has no pesticide residue, no environmental pollution, and effectively controls the occurrence and damage of pests and diseases. This paper introduces several methods of trapping.

1. Light trapping

Applicable to pest control in cotton fields, paddy fields and orchards, is increasingly being paid attention to and has become a hot spot for control. It utilizes the phototropism of pests, and artificially sets and selects lights to trap pests. Black light and double wave light utilize short light waves that are not visible to the human eye, and some object pests are sensitive to such light waves.SPRITEX insect killer manufacturer For example, the visual nerve of most pests is particularly sensitive to ultraviolet light with a wavelength of 330 nanometers to 400 nanometers, with strong phototropism and good trapping effect, which can trap a variety of pests. For example, cotton bollworm, rice leafhopper, rice louse, golden turtle and nocturnal moth family pests. For example, the trapping time of black light is usually from May to September, and it is economically appropriate to install one black light per 50 acres of cotton field at the peak of the pest season, with an installation height of about 1.5 meters. It is best to use a large caliber tank pots and iron pots as traps, containers filled with water, plus waste engine oil or chemical pesticides, glass baffles next to the lamp. After moth trapping, the amount of cotton bollworm eggs in the field can be reduced by 40% ~ 60%. High-pressure mercury lamps are even more capable of trapping pests, with a wavelength of 450 watts, ranging from 3,330 to 5,800 Angstroms. The maximum number of moths trapped by a single lamp was 12,000 in the second generation of cotton bollworm. It was observed that the number of eggs dropped by the second, third and fourth generations of cotton bollworms in the lighted area was 34.7%, 29.1% and 23.2% lower than that in the non-lighted area and all generations of cotton bollworms, respectively.

2. Plant trapping

The use of a variety of pests on some of the impact of plants have special feeding habits, artificially through the use of these research plants we tie the insertion of the soil field, or planting and management of these different plants in the field around life, so that it traps pests, such as cotton bollworms and bridge-builders adults to carry out has a tendency to plant, before spawning during the daytime themselves like to roost in the fresh products of the green bushes, and at night expresses the information of the social activities of foraging for food to cross the end of the night.Chinese RAMBO Insecticide spray Therefore, you can use poplar or willow branches tie handle, with a length of about 1 meter of small wooden sticks strung, inserted in the whole wheat field or cotton field (about 10 per acre), to induce moths to concentrate a hiding place. Early in the morning before sunrise (moths are not easy to fly away), with a plastic bag or gently put the branch handle set, and then pulled up, on the ground a few times, remove the composite plastic bag, pick up moths to death. Newly placed branches and put the same day to induce the emergence of adult insects, after a day, poplar or willow branches and leaves wilted after the issuance of such a special odor problem can be induced to a large number of insects and moths. In addition, such as planting castor in the corn field, it can trap the golden tortoise, and planting development corn in the cotton field can trap the cotton bollworm and so on.

3. Sugar and vinegar liquid trapping

The adult beetles of the Carter bug and the oblique night pirate have a strong preference for sweetness and sourness. You can prepare syrupy venom (500 ml of water, 250 ml of rice vinegar, 50 ml of wine, 40 ml of dichlorvos insecticide ratio), use three sticks about 1 meter long on a tripod in the field, put a small pot on the tripod, and then pour the prepared syrupy venom into the pot, and all kinds of insects come near to the field, smell the syrupy smell and fly to suck it, and then fall into the water and die. Put 3 ~ 5 pots per acre, change the dressing every night for 3 ~ 5 days.

4. Sexual attractant baiting

Insects can survive in complex environments, including many unfavorable and even hostile environments, because they have amazing adaptive capabilities, one of which is a highly specialized sense of smell. Utilizing this special sense of insects, odor lures have been developed, which can be categorized as sexual lures, food lures, or egg-laying lures. Insects exhibiting mating postures or attempting to mate with chemicals or objects containing chemicals may be sexually attracted. At present, the application of sex pheromones is becoming more and more widespread. China has been able to artificially synthesize more than 100 kinds of sex pheromones of pests, which are widely used in pest control of cotton, rice, sugarcane, corn and orchards, greatly reducing the occurrence of pests and the degree of damage, and reducing the amount of chemical pesticides.

5. Grass handle baiting

Wheat nightshade moths (stick insects) are the most important pests in the middle and late stages of wheat growth. Can be rice straw or millet grass tied into a bowl of coarse grass, with a small stick (70 ~ 80 cm long) string, one end inserted into the wheat field (10 ~ 20 per acre inserted), luring moths concentrated in the grass to lay eggs, 5 ~ 7 days for the new grass, and retrieve the old grass burned. Continuously insert the handle 2 ~ 3 times.

6. Baiting

Crush wheat bran, cottonseed, soybean cake to make bait and stir-fry, add 0.15 kilograms of 90% crystalline trichlorfon 30 times per 5 kilograms of bait, and add an appropriate amount of water to mix. Apply 1.5~2.5 kilograms per mu to bait crickets, tigers and other underground pests. Banana peel or pineapple peel 40 parts, 90% trichlorfon crystals 0.5 parts, add water to make a paste, set up 20 points per mu, each point put 25 grams, can trap fruit flies and other pests. During the larval plumage period of the tigress, collect fresh tender grass, dissolve 50 grams of 90% crystalline trichlorfon in 1 kilogram of warm water, and then evenly spray on the tender grass, put it next to the victimized plants, and then scatter it among the crops at night, and bait it with poisonous bait. Dig a 30-60 cm square pit in the field, put horse dung inside, and sprinkle a little trichlorfon powder under the dung to trap mole crickets. You can also set up a water tank in the field, a small amount of sesame oil and pesticide drops into the tank, also has a certain trapping effect.

7. Fly paper trapping

Utilizing as well as adult insects' tendency to yellow, set up yellow board trapping in the field. Will 50 × 20 cm front and back appear yellow hardboard coated with petroleum jelly or machine oil, hanging 30 to 50 pieces per mu, hanging in the same place with the plant has a high degree of development, can be trapped to a large number of aphids and other whiteflies and other pests. Fly paper baiting. In the pest problem occurs in the beginning of the bloom to the end of the bloom, each acre can be set up 15 ~ 20 baiting points, each point placed 1 fly paper, 3 ~ 4 days to replace 1 time, on the vegetables as the American spotted fly baiting effect is also very no obvious.
