How to control the longhorn beetle on peach trees? How to treat the longhorn beetle and some drill i

The rosé-necked longhorn beetle belongs to the Coleoptera longhorn beetle family, also known as the red-necked longhorn beetle, iron cannon insect, and hamper. It is mainly harmful to peaches, and occasionally harmful to apricots, elms, willows, etc.

From June to August, the branches are often inspected, and small fresh insect droppings are found, and the small larvae that are harmed by shallow damage are killed or dug up in time. Brush the branches with lime and sulfur mixed with whitening agent (10 parts of quicklime: 1 part of sulfur:

40 parts of water) to prevent adult worms from laying eggs. From June to July, when the adults are at their peak and the larvae are just hatching, spray 1000 times of 50% borer emulsifiable concentrate or 2000 times of 10% imidacloprid on the tree. Then there is wormhole application, the older larvae are bored into the xylem, spraying has no effect on it, you can take the method of wormhole application, clean up the fecal hole on the trunk, use a disposable medical syringe, pour 50% dichlorvos 800 times liquid or 10% imidacloprid 2000 times solution into the cavity, and then seal the insect orifice with mud.

The body of the peach tree is black and shiny; The dorsal plate of the prothorax is red, with 4 smooth verrucous processes on the dorsal surface with angular lateral branch spines; elytra wings smooth surface, base wider than prothorax, apex tapering; Male antennae adults have two color types: a "red-necked" type with a black shiny body and a brownish-red chest, and a "black-necked" type with a shiny black body.

The insect occurs in a generation of 2 years, and the larvae overwinter in the cavity of the trunk, and resume their activities in March and April of the following year, drilling irregular tunnels under the cortex and xylem, and excreting a large amount of reddish-brown fecal debris outside the cavity, piling up outside the hole and on the ground at the base of the trunk The most harmful in the month, when it is serious, the trunk is all hollowed out and died. After the larvae are mature, open a row of fecal holes outward, bond feces and sawdust with secretions, and make cocoons and pupate in the tunnel During the month, the adults bite and drill out after the adult emerges, and mate and lay eggs in the thick bark gap of the tree base and the main branches. After hatching, the larvae are first eaten under the skin and diapaused for the winter.

In the spring of the following year, it continues to eat the cortex, and in the middle of the month, it feeds upwards towards the xylem to form a curved tunnel, and then through the winter, it matures and pupates in the third year, and emerges into an adult.

1) Artificial control. Remove the dead branches and dead trees in a timely manner, and burn them in a centralized manner. In June and July, during the occurrence of adult worms, organize personnel to hunt and kill. During the larval period, the branches are often examined, and the larvae are found to be excreting feces and finding worm holes with wire hooks.

2) Coating white insect control: Before the adult worm lays eggs, brush the lime and sulfur mixture on the main stem and main branch and add an appropriate amount of contact insecticide.

3) Worm tract injection. After the fecal holes on the branches are found, the fecal sawdust is cleaned up, 1 4 tablets of 56% aluminum phosphide tablets are stuffed or 80% dichlorvos EC is injected 10-20 times, and all the fecal holes are closed with yellow mud, and the fumigation and insecticidal effect is very good. <>

Hello! Control measures for peach tree longhorn beetle:

1 Capture adults by hand. During the period of 6 and July, the habit of adults having resting branches from noon to 3 p.m. can be used to organize personnel to catch them in the orchard, which can achieve better control results. Hook a long bamboo pole with an iron hook to the branch and shake it vigorously, and the pests will fall to the ground one by one and catch them one by one.

2 Whiten the main branches. 4 During May, i.e. before the adult emerges, the trunk and main branches can be coated with a "white coat". Crack and void in the bark to prevent the adult from laying eggs.

3 Kill the larvae in advance. The larvae hatched before September are eaten under the bark, and the small reddish-brown feces can be found on the main trunk and main branches, and once the feces are found, the larvae will be killed by cutting the bark with a sharp knife. Branches can also be inspected in the spring of the following year, and if reddish-brown sawdust-like droppings are found on the branches, the larvae in the xylem are dug out with a sharp knife to kill.

4.Methods of drug prevention and control. During the peak stage of adult occurrence and larvae just hatching in 6 July, spray 10% imidacloprid 2000 times on the tree body, 7 10 days 1 time, spray several times.

Older larvae bored into the xylem can be treated by wormhole application. Clean the fecal hole on the trunk, fill the hole with dichlorvos tampon, use a disposable medical syringe, and pour 50% dichlorvos 800 times or 10% imidacloprid 2000 times into the cavity, and then seal the orifice with mud.

Peach tree longhorn, mainly harmful plant rhizomes, because the peach tree is not very large, so the control method is relatively simple, 1, take out part of the sawdust, 2, plug the insect hole with cotton. 3. Use Zhongwei Kuaihuo Forest "boring pest" to directly insert the worm hole in the trunk, 4. 2-3 times in a row, with an interval of 5-7 days.

The use of tree trunk drilling and injection to control pests is not only easy to operate, but also has remarkable effects. Moreover, it is a better control method to prevent and control dry-boring pests such as longhorn beetle and gidding insects, and to prevent and control leaf-eating pests such as aphids, scale insects and mites. According to the prevention and control practice in the past few years, we will talk about several problems that should be paid attention to in tree trunk injection.

1. Injection period.

The growth period from the bud germination period to the pre-defoliation period can be carried out, and the growth period from April to August is the best, and the specific injection time should be determined according to the growth history of the pests controlled. The dormant period between the time the tree has fallen leaves and before germination cannot be injected.

Second, the choice of pesticides.

It can be used with 50% methamidophos EC, 40% dimethoate EC, 75% wettable carbofuran powder, 50% nitrile EC, 50% monocrotophos EC and other strong systemic agents. Appropriate pesticides should be selected according to the different pests.

3. Injection method.

Use a carpenter drill with a diameter of 1 cm on the trunk of a tree 15 to 50 cm above the ground, and drill 8 to 10 cm deep injection hole obliquely downward at a 45-degree angle, which can reach the core of the medulla. Large trees can drill 3 to 5 holes in a spiral around the trunk, 2 to 3 holes can be drilled in medium trees, and 1 hole can be drilled into small trees, and the saw foam can be removed, and the liquid can be injected with an aspirator or syringe. If a large area is injected, a perforated injection machine can be used.

The orifice should be sealed dry (sealed with wax, mud, or adhesive tape). The injection hole can heal after two months.

Fourth, the amount of injection.

According to the size of the tree to determine the dosage, according to the original solution, generally the trunk diameter of more than 15 cm of large trees, each plant injection 6 to 10 ml, dry diameter of 10 to 14 cm of medium tree injection 4 to 6 ml, dry diameter of less than 10 cm of each plant can be injected 2 to 4 ml.

5. Precautions.

1. When the temperature is not high, 1 to 2 times of the liquid medicine can be injected, and when the temperature is high in summer, the original drug should be diluted 3 to 6 times and then injected, so as to avoid the drug damage caused by too concentrated liquidity.

2. For the tree species that are easy to flow gum, try not to drill holes, but use the method of drying the liquid medicine for control.

3. The injection should be based on the control object to choose the best endogenous pesticide with strong absorption, can not be divided into objects only use a certain kind of pesticide.

4. Do not use pesticides that are sensitive to trees to avoid pesticide damage.

Summary. First of all, in addition to the treatment of dry boring pests, you can take root buried iron to kill the gram, Shennongdan, aldicarb and other pesticides, you can also use poison sticks to plug the cavities to kill the dry boring pests, eliminate the harm, and then apply organic fertilizer and fast-acting fertilizer to fertilize the soil, enhance the tree potential, and achieve the purpose of restoration.

Hello, I have seen your question and am sorting out the answer, please wait for a while First of all, you can take pesticides such as root buried iron to kill Ke, Shennongdan, aldicarb, etc., and you can also use poison sticks to plug cavities to kill dry borer pests, eliminate harm, and then apply organic fertilizer and fast-acting fertilizer to fertilize the soil, enhance tree potential, and achieve the purpose of restoration.

Is it possible to sprout again? How long does it take?

Not sure. Top application of high-temperature disinfection of chicken manure and sheep manure.

May I? Do you use watering rooting powder?

It can't be used. Burned.

You say that you should apply organic fertilizer, what fertilizer should be applied? How to fertilize?

Wake up slowly.

In recent years, peach aphid control has indeed caused headaches for farmers. Many pesticides, because of years of use to develop resistance, peach aphids are extremely difficult to fight. Here I recommend a comprehensive peach tree control program on our side. Peach aphids are heavily overlapping in generations, so targeting such pests must start with egg killing.

There are three major types of peach aphid pests: peach aphid (tobacco aphid), peach flour aphid and peach tumor aphid, all of which are harmful on the back of the leaves, and the peach tree can not grow normally, affecting the yield and quality of peaches, and causing economic losses to farmers.

<> prevention and control measures.

Strengthen orchard management, combined with spring pruning, cut off damaged branches, and burn them or dig pits to bury them. There are many species of peach aphid, among which peach red aphid, peach powder aphid and peach tumor aphid are the mainstays, which occur in 10 or even more than 20 generations a year, and often overwinter with eggs in twigs, axillary buds and cracks. When the peach tree sprouts the following year, the eggs begin to hatch.

In addition to doing a good job in clearing the garden, we should also strengthen the management of peach bud germination: strengthen cultivation management, reasonable pruning, pay attention to variety configuration, and create a biodiversity planting environment, because the appropriate shade environment is more harmful to the peach tree than the aphids, such as meadowsweet aphid, etc., before harvesting wheat is the main control period, with bifenthrin + acetamiprid. With averospirofen, such as the trade name, Leiluo, thank you, the species of aphids that harm the peach tree, I won't talk about this, the aphids are classified as stinging insects, and the agents used are the same, like I dispense pesticides to farmers and friends, first of all, I know what insects, and then compound what family the insect belongs to, the purpose of the drug.

Due to the influence of weather and the natural environment, the current citrus management in the growth cycle, basically the first month to carry out the drug, so the harm of the adult beetle on the citrus tree, has been basically prevented and controlled. Sawdust. At this time, it is the best time to eliminate the larvae of the "longhorn beetle", most fruit farmers will use medical injection needles to suck enough organophosphorus pesticides into the vent to poison the larvae of the longhorn beetle, with this method we admit that the larvae of the longhorn beetle were poisoned, and at the same time the central duct part of the trunk was also burned to death.

During the occurrence of longhorn beetle, the trunk boreholes are stocked with parasitic eggs such as pine wood nematodes and Zeiza. After the natural enemy eggs hatch naturally, they burrow into the larvae and feed on the larvae to complete their life cycle. In addition, natural predators such as woodpeckers can be protected and used to control the occurrence of longhorn beetles.

Sweet and sour liquid trapping: Adults of the macular star longhorn beetle have a tendency to sweet and sour. Melt the sugar and water together with 5 parts sugar, 20 parts vinegar, 2 parts liquor and 80 parts water, heat to boiling and spray drying

In June-July, the adults are in full bloom and the larvae are just hatching.

Before the adult worm lays eggs, the branches are coated with white coating, and the larvae are manually killed during the adult generation period, and the larvae are pierced with iron wire; A syringe can be used to inject fumigation agents such as phenoxycarb and chloramidophos into the cavities; It can also inject 2000 times of the emulsifiable concentrate of the enemy, and plug the worm hole with mud in time after injection, which can generally achieve 90% control effect, and if the follow-up inspection also finds insect feces, the second plugging can be carried out.

It is the red-necked beetle that harms the peach tree:

1. Whitening of the trunk: Apply white coating on the trunk and large branches before the occurrence of adults to prevent egg-laying.

2. Manual killing: manual capture at noon during the adult occurrence period.

3. Dig with a knife: From July to August, look for insect droppings on the trunk and large branches, find fresh insect droppings, and dig out the larvae in the cavity with a knife.

4. Chemical control: the smaller the larvae, the earlier the treatment, and the less harmful it is to the tree. Therefore, it is necessary to control the larvae as early as possible during the active period of August and September.

One is to use poisonous cotton balls to plug the insect holes, which are soaked in 500 times dimethoate or dichlorvos; The size of the cotton ball depends on the amount of feces. After the cotton ball is plugged, the fecal discharge hole is sealed tightly with yellow mud in order to give full play to the fumigation effect of the drug; The second is to inject dimethoate 1000 times or dichlorvos 800 times into the cavities.
