Do you know anything about the hazards of wax scales in longan garden?

What do you know about the hazards of "the hazards of wax mealybugs in the longan garden?" Let me express my personal opinion here. In the longan garden planted in our lives, there are often piles of wax mealybugs that cause harm to our longan trees, so what harm will piles of wax mealybugs cause to our longan trees?

For example, the wax beebug will reduce the yield and quality of our longan tree longan, deform the young branches of our longan tree, wilt the leaves, etc., so we need to prevent the wax mealybug, for example, we can cut off the branches and leaves of the longan tree that are too dense, cut off the branches with wax mealybugs, and then burn them several. Or we can also breed pheasants, and if the wax whiteybugs are frightened, they are likely to fly to the ground and just let the pheasants eat them.

In life, our longan tree is likely to be attacked by wax whiteybugs, so what kind of harm will this pest called wax whiteybugs cause to our longan trees? The main way of harm is to use the stinging and sucking mouthparts to suck the branches or leaves of our longan tree to absorb the nutrients of the sap of the longan tree, etc., which is the withering and deformation of our longan leaves. The appearance of the longan fruit will be damaged, and the flesh of the dragon rock will become fishy.

Seriously affect the yield and quality of longan trees. <>

For the invasion of wax whiteybugs, we can directly remove them manually, for example, cut off the overly dense branches and leaves of the longan tree and the branches with wax mealybugs, cut them off and burn them intensively. We can also use tools to brush off all the wax bugs and dispose of them in a centralized manner. <>

In addition to artificial removal, we can also breed pheasants in the longan garden, because the pheasant eats the pile of wax mealybugs, when the pile of wax mealybugs grows into adults, they are easy to fly away when they are frightened, and if they land, they are just eaten by the pheasants, and the pheasants are also raised after removing the pile of wax mealybugs. <>

After reading it, I hope you can give me a like and pay attention

There is still a lot to know, which will cause the yield of longan to become lower and lower, and at the same time, it will also cause the new shoots of longan to appear distorted or deformed, which will also affect the fruit and the growth rate.

First of all, it is likely to affect the yield of longan, it will also cause the leaves to turn yellow, it will also affect the flesh of longan, it will cause the trees to wither or deform, and it will also cause the fruit to have a fishy smell, affecting the quality of the fruit.

It is easy to affect the growth and development of fruits, and the seedlings are easy to be deformed, which is not conducive to fruiting, and is also very harmful to the leaves, and it is easy to cause coal stain disease, resulting in the appearance of the fruit becoming unsightly, and the overall quality and yield of longan will be affected.

In addition to longan, there are many plants such as lychee, citrus, and mango. Adults and nymphs often gather on young shoots, fruit stalks, fruit pedicles, petioles and twigs to suck sap, and secrete many white waxy flocculents, which can also induce soot disease. The new shoots of longan are damaged, causing distortion and deformity, and the growth is stunted, which affects the results of the next year; Fruit damage, in addition to affecting the appearance and quality, also causes fruit drop.

If you want to solve the problem of wax mealybugs in the longan garden, the best way is to use pesticides, because pesticides can kill germs.

In the face of such a situation, you can spray some pesticides, and you can also use some bacteria and insect control agents, dilute them and spray them in the dragon fruit orchard.

You should use relevant pesticides, which can be diluted with water, and spray them on the plants with a watering can every day, so that the pest and disease can be solved.

There is a thick layer of fat underneath the eyes, which can greatly protect the Arowana from too much damage. In nature, fighting is inevitable. When the Arowana is fighting, it is easy to hit its eyeballs.

The fat around the eye socket actually acts as a buffer to prevent too much damage to Yu Qiyu's eyes. If there is a difference between obese and non-obese: two people fall from a height of 100 meters, one with a concrete floor and the other with a thick air cushion, the effect is obvious.

When the Arowana rubs against the tank, the eyeballs will be sunken, and if you look closely, you will see that when it is sunken, the white substance will be expelled from the edge of the eye socket, which is the fat around their eyes.

<> because the surface of the bug is covered with a thick layer of wax, it can multiply quickly and cover severe generations. Spring is coming. There are a lot of scaly insects on the flesh flowers and kumquats in the house.

Don't underestimate this small scaly insect. If it cannot be avoided and controlled for a long time, it will not only directly affect the ornamentation, but also directly lead to the weakening of the growth of flowers, the color of the leaves withering, and even the death of the whole plant.

Adult: The female body is three-long, flattened, oval, pink, covered with ash powder, the edge of the body has 17 pairs of white ash, and the last set of wax spines behind the body of the insect is too long. The total length of the male bug is about 1 mm, spreads 2 mm, and is purple-brown in color.

On top of this is the scale of the shell insect between the green-orange cotton (white part).

Nymphs and adults clump together to form leaves. We can clearly see that these greenish-orange layers of cotton wax appear in clusters at the base of the ruined scattered canopy. In the early stages, the lesions are yellow patches, which gradually connect into yellow-brown patches, and eventually lead to weak decay.

When the fruit is infected, in the early stages, water patches appear on the top of the fruit, then the lesions expand and turn into yellow chestnuts, and then the fruit rots. Fallen leaves and fruits, with many white cotton wool-like waxy secretions attached to the damaged branches and leaves, can induce soot disease.

There are many reasons for this, such as the management of the park is not in place, and the branches are more extensive. Longan garden must be finely managed, if there is a lot of stagnant water and a lot of fallen leaves to be cleaned up in time, for some branches if there has been rot, has withered, has been broken, then to clean up and prune in time. If there are a lot of weeds in the park, and there are a lot of insects that are not treated in time, then it is easy to appear a large number of wax mealybugs.

In particular, there are a lot of leaves and branches rotting, and it is easy to form stagnant water in rainy weather, so it is easy to appear a lot of germs and bacteria, and some insects, which will lead to a lot of pests and diseases. The management of the orchard can not be left alone, we must manage carefully, weeding and pests can not be sloppy, because sloppy will affect a harvest of longan, directly affect our economic benefits. <>

Every pest has natural enemies, and if pesticides are used too much and pesticides are used indiscriminately to kill some natural enemies, it is naturally easy to have a large number of wax mealybugs. The protection of natural enemies itself is a matter to pay attention to in agricultural planting, natural enemies are gone, which will increase the cost of our orchard management, so when we choose pesticides, we must carry out according to this amount, do not abuse pesticides, otherwise the consequences can only be borne by ourselves. For example, there are some birds, we don't do a lot of removal, it will eat a lot of bugs in the orchard.

Changes in climate and environment can also cause a large number of wax mealybugs. In fact, there is sometimes a period of time every year when the climate is changeable, either it is continuous rainy weather, or it rains today and the sun will be big tomorrow, so this kind of low and high weather changes are easy to cause pests and diseases. It is best to take precautions in advance during these weather processes, or when these weather comes, do the corresponding drainage work, and do the corresponding ventilation.

This is because when planting longan, there will be such a hidden pest and disease in the hall, which is also a very common pest, and it is also because of the influence of the burning bridge environment and temperature, and it is also related to the usual planting technology, so there will be a large number of wax mealybugs.

It may be because you didn't spray pesticides, didn't control pests, and didn't manage the field well, so such bugs appeared.

It may be because of improper management, or there is no ear cavity to prevent insect pests, or it may be that the control and suspicion system is relatively poor, or the method of handling the circle is wrong, and there is a problem with the prevention and control method.

What are the harmful symptoms of longan wax mealybugs? How can farmers control longan wax mealybugs? For farmers who grow the dragon's camouflage eye, these are the questions that they often have to think about when encountering wax mealybugs.

Harmful symptoms: Adults and nymphs feed on the juice of young leaves, leaves, flower spikes and fruits, which affects the normal growth of plants and causes flower and fruit drop. In addition, the honeydew secreted by this type of pest is easy to induce soot disease.

Occurrence pattern: 1) Occurrence generation. 5-6 generations occur every year in South China.

2) Overwintering. Nymphs and female adults overwinter in the bark crevices of branches and leaf curls.

3) Period of occurrence. It is active in February and lays eggs in oocysts in late March. The nymph bloom in early April, mid-May, mid-July, mid-September, early October, and mid-November.

In April-May and September-November, the insect population density was the highest, and the damage was the most serious.

Prevention and control methods: 1. Do a good job in orchard control, fertilization, frost prevention and other pest control work. Cultivate the tree and improve the insect resistance of the tree itself.

2. Combined with winter pruning, cut off insect branches, shade branches, and dry branches in time before April to reduce the source of insects, improve the ventilation and light transmission conditions of the orchard, reduce the damage of sagittal scales, and pruning must be burned intensively.

3. Frequently inspect the garden during the peak fruit period, if it is found that there are sagittal scales on the fruit surface and branches, remove them in time, and concentrate on treatment to reduce the damage of sagittal scales to fruits.

4. The agent for the prevention and control of wax mealybugs is mainly used to use 40% rapid culling of 700 900 times of emulsifiable concentrate to pick and treat adult scales. For the prevention and control of, you can generally choose 40% chlorpyrifos milk car oil 1000 1200 times, or bitter tobacco water 1000 1200 times, or 25% chlorpyrifin 1300 1800 times. The best control period was the nymph blooming period for each generation.

If it is severe, it can be treated 2 or 3 times at an interval of 15 to 20 days.
