The fig tree has insects, how to kill them

During the fruit growth period, the special smell emitted to the surroundings is easy to attract the harm of the mulberry beetle; In addition to manually catching mulberry beetle, it can be artificially or druggically exterminated eggs. From the ** you sent, you can understand that this is indeed the larva of the mulberry beetle.

Mulberry beetle Mulberry beetle is widely distributed and is the main pest of fig trees, and the damage state: Mulberry beetle mainly harms the branches of fruit trees. Adults eat the bark of young branches, and the scars are irregular strips, and the bark of the branches is gnawed away in severe cases, causing the branches to break and die easily.

Adults lay eggs on branches in the middle of the groove. After the eggs hatch, the larvae feed down along the xylem and pith in the branches, and can eat to the roots, resulting in poor plant growth and premature tree aging, affecting the fruit yield of the year, and the cold tolerance of the tree body is reduced, and it is easy to freeze damage, and the whole plant dies in severe cases. The larvae overwinter in the cavity of the branches, and the overwintering larvae begin to sting in early to mid-March, and enter the peak period of damage in April and May.

In late May, the mature larvae move up the insect road to pupate in the pupal chamber, and the adults eat the new shoot skin of figs after emerging in mid to late June, and lay eggs on the branches, and the oviposition is in full August. The hatchling larvae feed directly into the xylem and feed on the base of the trunk, and the larvae bury up a meter in their lifetime. In mid to late November, the larvae stop feeding and enter the overwintering state.

Control method: cultivation and control According to the characteristics of mulberry and oak trees, mulberry trees or oak trees are used as the inducement tree species. That is, mulberry trees or oak trees are planted 100 meters away from the fig orchard as a protective belt for isolation.

During the occurrence of mulberry beetle, spray the mulberry tree for control, and pay attention to the timely and thorough control of the tree. In order to reduce the source of insects, the damage to fig trees.

Artificial control Before the occurrence of adult insects, apply white coating (i.e., 10 parts of quicklime, 1 part of sulfur, and 40 parts of water) to the trunk and large branches to prevent and control the adult insects to lay eggs. In the adult occurrence period of mulberry beetle, the adult worm is caught in the morning and evening. In July and August, the eggs are manually dug out, and the oviposition groove is checked every 7 10 days, and the eggs are pierced with a knife or the hatched larvae are pierced to death at the groove, and the eggs can be dug 2 or 3 times to control the larval decay.

During the larval occurrence period, when the lake is found to be moist and fresh, the insect feces are first stripped with iron wire, and then the aluminum phosphide tablets are stuffed into the fecal holes, and the insect holes are sealed with slime for fumigation. Or use a veterinary syringe to inject 40 50 times of 40% dimethoate emulsifiable concentrate into the fecal discharge hole, and then plug the worm hole with mud to prevent the outflow of the liquid.

Here's how to fix it:

1.The use of inulin pesticides for control (agricultural seed dealers sell), because the toxicity is small, the residue is short;

2.Do not use dimethoate, oxidized dimethoate, oxymethoate pesticides, so as not to cause flower and fruit drop;

3.After spraying, hang eye-catching signs, such as "pesticides have been sprayed, no picking" and other words, to prevent unforeseen consequences.

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.

The ** method of growing insects on fig trees is as follows:

Prune branches and leaves. If there are insects growing on the fig tree, you need to prepare a pair of 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.

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.

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

Pull out the bugs. There are insects in the fig tree, you need to prepare a stainless steel wire, and 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.

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.

Fig tree insects can use solutions such as dimethoate, trichlorfon, green worm fungus, and dichlorvos. During the growth period of fig trees, with the growth of tree age and mold decay, the degree of canopy closure in the field increases, which is prone to the production of mulberry beetle, anthracnose and nematodes. If there is a mulberry beetle on the fig tree, you can use 100 times of 40% oxidized dimethoate, and you can also hang it on the fig tree to hunt and kill the mulberry beetle.

Maintenance of fig treesFig trees in autumn after the fall of leaves with a whitening agent to coat the trunk, with anti-freezing, eliminate pests and prevent animal gnawing and other effects, young tree branches are fewer, after the leaves are pruned to bury the soil for cold protection, adult trees need to wrap the trunk with cold-proof non-woven fabric foam cold-proof materials and other wrapping treatment.

Figs have well-developed root systems and are relatively drought resistant; However, due to the large leaves, the evaporation of water in the summer high temperature season is more, so the water demand is large, if the water is not satisfied, the growth of new shoots will be inhibited, the yield will be reduced, and the heavy will be small, the quality is poor, and even the leaves fall early; However, the rainy season requires timely drainage of stagnant water from the soil. Eyes are bored.
