The control method of gilding worm, the control method of gilding worm

Gidding insects, commonly known as popping skin insects and rusty skin insects, belong to the order Coleoptera and the Gidding family. Adult insects bite the leaves to cause a lack of carving, the larvae eat the cortex of the branches, and there is a flow of gum in the damaged place, and the bark bursts when the damage is serious, so it is called "popping skin worm", and even causes the whole plant to die. The size and shape of the adult worms vary depending on the species, ranging from smaller ones of less than 1 cm to larger ones of more than 8 cm, with small heads and short antennae and feet.

The larvae are long and flattened, milky white, most of them eat trees, and some of them eat in leaves, and when they are serious, they can make the bark burst, so they are called "popping skin insects". Gidding insect is an extremely beautiful beetle, the general body surface has a variety of colors of metallic luster, most of the colors are gorgeous and abnormal, like a delicate and charming lady, also known as the "rainbow eyes".

Strengthen quarantine to prevent the spread of Gidding worm with the transportation of seedlings. 2. Strengthen the maintenance and management of garden plants, especially newly planted trees, should timely replenish water to make them grow vigorously, keep the trunk smooth, and prevent adults from laying eggs or inhibiting the hatching of eggs; Before the adult emerges, remove dead branches, dead trees or damaged branches in time and burn them to reduce the source of insects. 3、

Artificial killing of adult insects vibrates the trunk in the morning before the water dries up during the occurrence period of the adult insects, and the adult insects are suspended by stepping on or falling to the ground with nets; When you find that the bark is upturned, peeled off and has insect droppings, immediately remove the insect droppings, catch the larvae, or poke them to death with a knife. 4、

Chemical control sprays the trunk with 1000 times of 80% dichlorvos EC or 2000 times of 10% cypermethrin EC before the adults break through the holes and fly out, that is, before the peak of emergence, to poison the larvae and adults and prevent the adults from flying out.

1) Artificial killing of adult insects: From the beginning of May, in the early morning of low temperature and high temperature during the occurrence period of adult insects, artificial vibrating and killing of adult insects is carried out once every 2 3 days.

2) Pesticide control of adult insects: In the adult occurrence period, 1200 times of 37% insect killing emulsifiable concentrate and 1000 times of 80% dichlorvos emulsifiable concentrate were selected for tree spraying to control adults.

3) Artificial larval extermination: During the overwintering period, scrape the coarse bark cracks on the main trunk and main branches of the pear tree to eliminate the overwintering larvae.

1) Artificial killing of adult insects: From the beginning of May, in the early morning of low temperature and high temperature during the occurrence period of adult insects, artificial vibrating and killing of adult insects is carried out once every 2 3 days. (2) Pharmaceutical control of adult insects

In the adult stage, 37% insecticidal emulsifiable concentrate 1200 times and 80% dichlorvos emulsifiable concentrate 1000 times were selected for tree spraying to control adult insects. 3) Artificial larval extermination: During the overwintering period, scrape the coarse bark cracks on the main trunk and main branches of the pear tree to eliminate the overwintering larvae.

4) Pesticides to control larvae: dilute 50% dichlorvos emulsion 20 times with kerosene and apply it to the bark above the larval insect tract to kill larvae.

1. Manual prevention and control of suspicion. Before the fruit spring tree germinates, it is combined with pruning, cutting off insect branches, and burning it intensively; Or use wire hooks to kill larvae in cavities. During the occurrence period of adult worms, the adults on the trees are artificially shaken, and their feigned death is used to manually hunt and kill, or use black light to trap and kill the adults at night.

2. Agricultural prevention and control. Strengthen cultivation management, reasonable fertilizer and load, enhance tree potential, avoid wounds, and reduce the occurrence of pests; Removal of senescent trees. For senescent trees that have lost their ability to bear fruit, they should be removed as soon as possible to reduce the density of insect populations in the field.

3. Chemical control. During the adult emergence, spray 2000 times of cypermethrin EC or fenvalerate EC on the branches. Wrap plastic film on the trunk of the tree, tie the mouth at the upper and lower ends, and fill 1 3 pieces of aluminum phosphide sheet to kill the larvae in the skin.

When necrosis or gum flow is found on the surface of the branch, the insect mouth is detected and the larvae are killed.

Summary. Before the adult emerges from the burrow, the trunk is closed with a drug. Starting from early May, when the adults are about to emerge from their burrows, spray the trunk and branches every 10 to 15 days with 600 times of 90% crystal trichlorfon or 800 1000 times of 40% dimethoate EC.

During the adult stage, spray 80% dichlorvos EC or 90% crystal trichlorfon 800 1000 times on the tree, and spray 2 3 times in a row.

Before the adult emerges from the hole, the trunk is sealed with a potion. Starting from early May, when the adults are about to emerge from their burrows, spray the trunk and branches every 10 to 15 days with 600 times of 90% crystal trichlorfon or 800 1000 times of 40% dimethoate EC. During the adult stage, spray 80% dichlorvos emulsifiable concentrate or 90% crystal trichlorfon 800 1000 times on the tree, and spray 2 3 times.

How to close the trunk.

Wrap a thin plastic imitation membrane on the trunk of the tree, tie the mouth at the upper and lower ends, and contain 1 3 pieces of aluminum phosphide to kill the larvae in the skin. When the surface of the branch is found to be necrotic or bleeding gum, the insect mouth is detected, and the larvae are killed in preparation for killing.

Six-star Gidding sheath copy

Pterodae, the family Gilbaitinidae, also known as string du

Skin worms, dried skin strings, etc. It is present in most of the northern provinces.

DAO distribution, harmful to apples, pears, dates, peaches, plums, apricots, walnuts, chestnuts and other fruit trees. The larvae eat the cortex and xylem of the branches, causing the branches to dry up and die.

1) Morphological characteristics of adults. The body is about 11 mm long purplish-brown, shiny, the antennae are serrate, and the compound eyes are oval black-brown. The wing sheaths each have 3 nearly circular green spots, 3 pairs of feet, and the basal segments are coarse.

Larvae. Creamy white or milky white, hypertrophic thorax, body length 15-25 mm, abdomen flattened cylindrical, thinner than thorax.

Ovum. Oval milky white.

2) A brief history of life The six-star gidding insect occurs in one generation every year, and its larvae overwinter in the insect tunnels in the trees. At the end of April of the following year, the mature larvae pupate in the xylem, and emerge as adults in May and June, biting through the epidermis and crawling out. After mating, eggs are laid in the cracks of the bark in the lower part of the trunk, and the larvae bury into the cortex after the eggs hatch and are harmful to overwintering.

Adults are suspended animation.

3) control methods agronomic measures, the use of adult feign death, can be in May and June during the adult period, early morning to the tree under the tree to vibrate the tree to kill, at the end of April and August and September, often check the tree body, found insect feces and insect holes, with a thin wire from the insect channel to dig out the dry larvae.

Drug prevention and control, inject 200 times of 80% dichlorvos emulsifiable concentrate into the larval cavity to kill the larvae and plug the worm holes with sludge, or soak the absorbent cotton ball with 50 times the liquid to plug the worm holes and smoke the larvae, and plug the wormholes with poison sticks to kill the larvae (poison sticks are available in the market).

Summary. A bottle of Toucui plus a bottle of Ruigong plus 10 bags of Jin Gaomeng, mixed with 200 pounds of water, sprayed on the whole plant. After 10 days, the control effect against beetles and gidding worms exceeded 90%.

The results of the 2018 study in Hebei showed that the number of dead pine trees in 2017 has decreased from more than 1,000 to more than 10 this year, with obvious economic benefits.

A bottle of Toucui plus a bottle of Ruigong plus 10 bags of Jin Gaomeng, mixed with 200 pounds of water, sprayed on the whole plant. After 10 days, the control effect against beetles and gidding worms exceeded 90%. In 2018, the efficacy results in Hebei Province showed that the number of Pinus tabuliformis trees had decreased from 1,000 in 2017 to more than 10 this year, and the economic benefits were obvious.

Is this the drug you are talking about a brand name? In Changchun, we don't seem to be able to buy its chemical name, and it is better to have a chemical name.

I'll find out.

It's good to look up dichlorvos and dimethoate on the Internet, so that you can know if it's feasible if you haven't used it, and you can add some other medicines, such as fenozide or something.

Comprehensive spraying prevention and control. Spray pesticides on all Pinus tabuliformis, Arborvitae orientalis and whitebark pine, and use 40% dimethoate, zinc poison or inulin pesticides for agricultural cooking, and use a slightly larger concentration than the description of cheating, such as purifying dimethoate with 40% oxygen, with a concentration of 800-1000 times. Prevent or kill adult worms.
