Fig trees have bugs that like to burrow in the tree, how to control bugs?

Figs with insects burrowing in trees are generally caused by mulberry beetles.

1. Mulberry beetle is manually killed during the oviposition period of adults from June to July every year. For fig trees with insect infestation in the previous year, inject 50 times of 80% dichlorvos EC or 40% pine borer into the wormhole at the last larval fecal hole of the branch stem in April-May and September-October.

2. Or use cotton wool dipped in medicine to plug into the worm hole, which has a good effect on killing larvae. It is also possible to spray the branches and ovipositions of the wine with a strong systemic insecticide, 40% dimethoate 100 times or 10% insecticide 100 times before the hatching larvae have not been bored into the xylem.

3. Spray 1500-2000 times of 90% trichlorfon in the larval stage, or 800-1000 times of dichlorvos, or 800 times of green worms, and the control effect is relatively good.

4. Tie the poison ring to the branch of the main trunk to poison the mature larvae that crawl down the ground along the trunk.

5. It can be used to trap and kill by setting lamps, and it can be used according to this insect situation.

6. In the peak period of adult insects, in the case of no wind at about 5 o'clock, use poplar (or willow) branches and leaves dipped in 80% trichlorfon 200 times liquid, every 10-15 meters a bunch inserted in the nursery or newly planted young trees to trap adults, can also be used to soak poplar (willow) branches with 50% monocrotophos 50 times solution for more than 10 hours, 5 inserts per mu into the ground, trap adults.

7. Soil treatment. 200-250 grams of 50% phosphine per mu plus 25-30 kg of fine soil, shallow hoeing after sprinkling; 250 grams of 50% phosphine EC add 1000-1500 kg of water and irrigate along the ridge; 2-3 kg of 2% methyl isosulfonate powder per mu, 25-30 kg of soil and 25-30 kg of soil are sprinkled along the ridge, and shallow hoeing.

8. Tree treatment. In the peak stage of adults, 80% trichlorfon 800 times, or 50% malathion emulsifiable concentrate 2000 times or 25% wettable carbaryl 1000 times can be used to spray the tree, and the effect is better.

9. During the occurrence period of the adult, use its feigned death to organize manpower to shake the tree body in the evening to shake it and kill it.

Adult insect control: longhorn beetle generally lie behind fig leaves after rain, knock with a wooden stick, trample to death after shaking off, and spray imidacloprid and other agents planted in a large area.

Larval control: Paper with insecticide is stuffed into a hole and sealed with mud.

Insect egg control: If there is a groove, it means that there are insect eggs, and they are scraped off with a blade and taken out of the orchard.

Stocking predators: Capture the velvet parasitic beetle and place it on the fig stalk to feed on the larvae.

Strengthen management: Reasonable pruning in winter and fertilizer and water management in the growing season.

1. Adult insect control.

Fig tree insect pests are mostly harmed by the beetle, and the activity time of the adult beetle is from June to July every year, and it is also a good time to eliminate the adult. The longhorn beetle generally lies behind the fig leaves after the rain, and after the rain, the tree trunk is beaten with a wooden stick to shake the adult to the ground, and then catch or trample it to death. If it is planted in a small area, this will reduce the harm.

If it is a large-scale planting, it is recommended to spray pesticides, choose pyrethroids, imidacloprid, chlorpyrifos, etc., and spray them once every 5-7 days, mainly spraying on the branches, and the effect is outstanding.

2. Larval control.

The larvae of the longhorn beetle gnawed on the main trunk of the fig, and if you see fresh excrement on the ground of the trunk, there are two cavities on the upper and lower cavities, it means that there are larvae of the longhorn beetle. You can spray the insecticide on the paper, wrap it with wire and stuff it into the hole, plug the upper and lower holes, and finally seal the mouth with wet mud. It can also be used at the hole of the larvae of the trunk to use dichlorvos emulsifiable concentrate or pine to kill the larvae by injecting the agent into the hole with a syringe.

3. Insect egg control.

The eggs of the longhorn beetle are generally laid in the main trunk 2-5 cm, if there is a groove, it means that there are eggs, which can be gently scraped off with a blade. If you see the leaves with insect eggs, you should also remove them in time, take them out of the orchard and bury them deeply or burn them directly to reduce the source of insects.

Fourth, put natural enemies.

The insect is the natural enemy of the beetle, and it will be caught on the fig stalk, and it will look for the place where the beetle lays eggs to prey on the larvae, and the pest control effect is good in this way, and there is no need to spray pesticides.

5. Strengthen management.

The weeds under the fig tree should be removed in time, and the branches should be pruned in winter, and the over-dense branches, dry branches, and diseased and insect branches should be pruned off to ensure internal ventilation and light transmittance. Tree trunks with holes are seen to block the holes with mud to reduce overwintering eggs. During the growth period of figs, it is necessary to apply organic fertilizer or phosphorus and potassium fertilizer in time to promote more robust growth and improve resistance.

Fig trees have insect trees and holes, which may be infested by mulberry beetle, and the treatment method is as follows:

Manual killing: Manual killing is carried out in July and August, and the eggs are manually dug up, and repeated many times in a row.

Drugs: Inject dichlorvos EC and pine borer into the trunk, spray dimethoate and insecticide before the hatched larvae have not eaten into the xylem, and spray trichlorfon, green worm fungus, dichlorvos and so on at the larval stage.

Light Booby-Trap: Hang a lamp next to a fig tree for booby-trapping.

1. The reason why the fig tree has bugs and the tree has holes.

The fig tree has bugs and holes, which may be infected with mulberry beetle. Mulberry beetle will gnaw on trees, adults will eat tender branch bark, the scars on the trunk are irregular strips, when the harm is serious, the bark will be gnawed away, easy to cause the fruiting branch to break and die, the larvae in the branch along the xylem, the pith down to eat, easy to lead to poor growth, premature tree aging, seriously affect the yield of the year, will make the cold tolerance worse, serious cause the whole tree to die.

Second, the control method of fig trees with insects and holes in trees.

Manual killing: Manual killing is carried out in July and August every year, the eggs are manually dug up, the oviposition groove is checked every 7-10 days, and the eggs are punctured or the hatchling larvae are pierced at the groove with a knife, so that the larvae can be completely controlled by repeating several times in a row.

Use of drugs: After the fig tree finds the mulberry beetle, you can inject drugs into the trunk of the tree, and use a syringe to inject 80% dichlorvos EC or 40% pine borer 50 times into the wormhole at the last larval fecal hole of the branch in April-May and September-October. Before the hatched larvae have not penetrated the xylem, they can be sprayed with 40% dimethoate 100 times or 10% insecticide 100 times on the branches and oviposition.

In the larval stage, it can be sprayed with 1500-2000 times of 90% trichlorfon, 800 times of green worms, 800-1000 times of dichlorvos, etc.

Light booby-trap: Hang a lamp next to the fig tree, take advantage of its phototaxis, and set up a light booby-trap.

There are four methods, which are as follows:

1. Tidying up: cleaning once a week can not only clean the home neatly and neatly, but also reduce the breeding of insects;

2. Frequent drying: sunlight is a good way to sterilize, seasonal clothes, bed sheets, quilt covers, furniture, etc. need to be dried, especially in the rainy season;

3. Frequent sterilization: You can put a basin of clean water in the corner of the house for a long time, and put chopped onions in the water, which can not only increase the air humidity of the room, but also sterilize and prevent insects;

4. Good storage: Foods that are easy to grow insects should be eaten as soon as possible or stored correctly, such as sesame seeds and mung beans are very easy to grow insects, so they should be sealed and preserved.

Then I'll teach you a trick, you can use the relevant pesticides to spray on the trunk of the tree where they are digging, as long as you spray the pesticide in advance, you can try to make a hole in them! It's no wonder if they don't poison them when the time comes.

You are really a child, you are not sensible, the figs have been eaten by insects and have many holes, which means that there are insects in it, and he is eating them in it, how can you seal the hole? Even if the hole is blocked, it will bite through another hole from the side.

In the spring of each year, if insect feces are found, 1:10 methamidophos or dimethoate should be used to inject worm holes, and at the same time, after the injection is completed, the worm holes should be blocked with mud, under normal circumstances, it is necessary to control about 3 times in a row, and then there is no new worm hole on the same trunk. After completing the drug injection of wormholes, it is necessary to use quicklime, sulfur, and water in accordance with 10:

The ratio of 1:40 is applied to the trunk and main branches of the fig, which can effectively prevent the laying of eggs by adults such as mulberry beetle.

Hook out the larvae: The fig tree has bugs, and you need to poke a wire into the hole to hook the larvae out. Injection solution:

Inject dichlorvos emulsifiable concentrate or imidacloprid solution into the tree hole. Pruning of branches and leaves: Cut off severely infected branches and apply varnish.

Weeding and fertilizing: Pull out weeds near fig trees to reduce insect sources.

1. Tick out the bugs

There are insects in the fig tree, you need to prepare a stainless steel wire, then glue the head with cotton, and then poke it into the hole, turn and turn to stab the larvae to death, or bend the wire into a hook, reach into the bottom of the hole and slowly dig out, and hook the insects out.

2. Liquid medicine for injection

When breeding fig trees, if you find that there are wormholes on the branches of the plant, you should use dichlorvos emulsifiable concentrate, imidacloprid and other preparations to prepare an aqueous solution, and then put it into a syringe, inject the liquid medicine into the wormhole, kill the larvae, or use a cotton swab to dip the liquid medicine directly into the wormhole.

3. Prune branches and leaves

If there are insects in the fig tree, you need to prepare a sharp and sterilized scissors to cut off all the branches and leaves of the plant that are seriously infected to avoid infection, and apply plant ash or varnish to the broken part of the fig tree to disinfect and sterilize it to avoid plant rot.

4. Weeding and fertilizing

When breeding fig trees, it is necessary to pull out the weeds near the plants in time to avoid robbing the trees of nutrients, and at the same time can reduce the source of insects, and in the flowering and fruiting period of the fig trees, apply phosphorus and potassium fertilizer or well-rotted organic fertilizer once a month to make the plants more robust and avoid their infection with diseases.

1. Prevention and control methods of Sangtianniu: the oviposition period of adult worms collapses in June and July every year, including manual killing; For fig trees with insect infestation in the previous year, inject 80% dichlorvos EC or 40% pine borer 50 times into the wormhole at a larval fecal hole in the branch stem from April to May and September to October. Or use cotton pad dipped in the agent to plug into the worm hole, and the larvae killing effect is good.

2. Spray 1500-2000 times of 90% trichlorfon in the larval stage of yellow thorny moth, or 800-1000 times of dichlorvos, or 800 times of green worm fungus, and the control effect is relatively good; Tie the poison ring to the branch of the main trunk to poison the mature larvae that crawl down the ground along the trunk; It can use its phototaxis, set up lamps to trap and kill, and can be based on this ** insect situation. In the peak period of adults, the poplar (or willow) branches and leaves are dipped in 80% trichlorfon 200 times the liquid at about 5 o'clock without wind, and a bunch is inserted in the nursery or newly planted young trees every 10-15 meters to trap and kill the adults, and 50% monocrotophos 50 times can be used to soak the poplar (willow) - branches for more than 10 hours, and 5 sticks per mu are inserted in the ground to trap and kill the adults; Soil treatment.

Adult insect control: spraying pyrethroids, imidacloprid and other agents to control longhorn beetle insect pests. Larval control:

Spray insecticide on the paper and wrap it with wire into the hole where the larvae eat. Stocking natural enemies: Place the velvet parasitic nail on the stem of the fig.

Daily management: Remove weeds under the fig tree in a timely manner.

1. Adult insect control

Fig trees are most susceptible to the invasion of the insect pest, the longhorn generally lies behind the leaves, you can use a wooden stick to hit the trunk, the adult insect is shaken down, and then caught or directly trampled to death, if it is a large area of planting plants, spray pyrethroids, imidacloprid and other agents to prevent and control.

2. Larval control

The larvae mainly eat in the trunk of figs, if you see two aphid holes in the trunk, it means that there are larvae in it, you can spray insecticides on paper, wrap them with wire and stuff them into the hole, and finally use wet mud to seal the hole.

3. Put natural enemies

The natural enemy of the beetle is the velvet parasitic beetle, this insect can often be seen on the carob vine, it can be caught and placed on the stem of the fig, the velvet parasitic beetle will automatically find the larvae to prey, this way of insect control effect is good, and there is no need to spray pesticides.

4. Daily management

In the daily maintenance of fig trees, remove the weeds under the tree in time, prune the branches when clearing the garden in winter, cut off dense branches, dead branches, diseased branches, to ensure the internal ventilation and air permeability, and at the same time during the growth of the plant, it is necessary to timely top dressing, and the fertilizer is mainly organic fertilizer or phosphorus and potassium fertilizer to improve the disease resistance of fig trees.
