Biological characteristics of the bark beetle
The apple bark beetle is a brown (dark brown) beetle. Body length no more than 4 mm. Adults fly. The stiff wing liners are dotted with parallel stripes. In the spring, during the period of mass flowering of fruit trees, insects begin years. Females choose a tree for themselves, gnaw passages in it, lay eggs. From them, larvae appear - white worms with powerful jaws.
The larvae cause the main damage to the tree. Until next spring, they feed on wood and eat up the trunk. Before becoming an adult, they pupate. In the spring, the developmental cycle is repeated (imago, egg, larva, pupa, imago).
Types of bark beetles
Bark beetles are a threat to trees, wooden buildings, wooden products. There are 750 species of wood pests in the world. The most common types are:
- Sapwood.
- Bread beetle.
- Printer.
- Furniture grinder.
- Woodworm beetle.
- Xylophage.
- Shashel.
Why is the bark beetle dangerous for an apple orchard?
A small beetle can destroy an entire garden. As a victim, the bark beetle chooses fruit trees in which, due to improper or thickened planting, the root system is poorly developed, there is mechanical damage on the bark.
There are times when pests attack an absolutely healthy apple tree.
Pest larvae eat wood around the entire circumference of the trunk. The nutrition of the tree is deteriorating, and the infection penetrates through numerous moves. Apple trees die due to lack of nutrients and fungal diseases.
How to detect the presence of a bark beetle: traces and signs of parasitism
It is necessary to inspect the trunks of apple trees in order to identify the pest in time. Birds arriving in the garden can become indicators. It is worthwhile to be wary if a woodpecker is wielding it.
Visual signs of the apple bark beetle:
- holes on the surface of the bark;
- gum drips;
- dust, resembling fine sawdust in structure.
The color of the dust determines the degree of damage. Dark is the initial stage. The beetle did not penetrate deep into the tissue of the tree.Light sawdust indicates that the beetles have eaten the wood deeply and it will be difficult to save the apple tree.
Fighting the parasite with chemical components
First of all, the degree of damage to the tree is determined in order to determine how to deal with the beetle. All methods will be useless if the crust falls off in pieces. If it holds firmly, there are few holes in the trunk, the apple tree can be saved.
Types of funds
To combat the bark beetle, insecticides are used. They give preference to drugs with a wide spectrum of action. They penetrate deeply into the tissues of the tree, act on larvae and adults.With the help of chemicals, the crowns of fruit trees are treated before the beginning of summer of the beetle. Spraying is repeated after 2 weeks. In addition, trees are fed with fertilizers, they carry out sanitary pruning, removal of old stumps, and traps are hung around the garden.
"Senezh-Insa"
This tool for processing wood and lumber products is produced by the Russian company Senezh. The water concentrate is sold in plastic containers with a volume of 5 liters and 60 liters. The agent penetrates deep into the wood tissue. Processing results:
- larvae, adult beetles die;
- bacteria, fungi do not multiply;
- the drug repels new pests.
The cost of the product in a canister is about 600 rubles, in a large container - about 4000 rubles.
"Clipper"
Russian insecticide-acaricide, analogue of the drug "Tolstar" produced in the USA. Purpose of use - pest control on vegetable crops. The product can be used in greenhouses.
Release form - emulsion (concentrate), packing:
- containers with a volume of 5 liters;
- 1 liter bottles.
Preventive apple processing spend a week before the mass summer of beetles. The protective effect lasts from 20 to 30 days. Treatment of trunks (⅔ height) is carried out using an industrial spray, a 3% solution is prepared. "Clipper" destroys larvae and adults of bark beetle, kills other pests of the garden.
"Vitalizer NV-101"
Non-toxic preparation, all active ingredients of natural origin. The tree protects from pests and infections an extract obtained from plants (plantain, pine, cypress, cedar). Release form HB-101: granules, liquid.
Processing scheme:
- after flowering, the first spraying of the apple tree;
- 2nd and 3rd treatments are carried out with an interval of 7 days;
- the solution is prepared from 10 l of water and 1 ml of the drug.
"Bi-58"
The German remedy is effective against beetles and larvae. It, getting into the intestines, causes their death. The drug is in the form of a concentrated emulsion. It is packed in containers with a volume of 1 to 10 liters. BI-58 can be mixed with Clipper. This enhances the therapeutic effect of the insecticide. The product is toxic to humans and bees.
It must be used carefully, strictly following the manufacturer's recommendations.
Treatment and prevention with drugs
An approximate action plan will help to treat apple trees from bark beetles, to carry out preventive treatments.
Period | Spraying agent | other methods |
Before bud break | Top dressing using "Diammofoski" | Sanitary trimming, whitewashing of the trunk |
During the opening of the leaves | Root dressing "Gumi-30 Universal" | |
The beginning of flowering | Treatment of the crown with "Rich-Micro", the trunk - "Bitoxibacillin" | Hang antiferomone beetle repellents on trees |
End of flowering | Treat the trunk with Confidor Extra twice (interval 14 days) | |
Treat the sheet with HB-101 | ||
When a pest is detected | Clear the passages | |
Syringe with Confidor Maxi solution | ||
Cover the holes with pitch | ||
Scatter "HB-101" granules in the near-trunk circle, embed them in the soil | ||
In autumn, after the foliage has completely fallen | Sanitary pruning | |
Destruction of leaves | ||
Whitewashing of the trunk, skeletal branches |
Traps and scarers
Special traps treated with pheromones are sold in gardening stores. They are laid out in the garden from spring to early summer. The smell attracts adults. Beetle traps are destroyed.
The principle of operation of scarers is different. The devices emit a threat smell or danger signal. By this, they force the beetles to look for another habitat.
Barrel injection
You can get rid of the beetle in the early stages of the lesion with the help of injection. Solutions of drugs can be injected into the passages:
- "Antizhuk";
- "Calypso";
- "Confidor";
- "Karbofos".
A large syringe is needed to carry out the work. Processing stages:
- Solution preparation.
- Introducing liquid into the hole
- Covering the course with garden pitch.
Traditional methods
If beetle moves are detected, the apple tree trunk must be coated with a mixture of manure and slaked lime in a 1: 1 ratio. Dense application guarantees a positive result. Damaged apple trees can be treated with a solution prepared from the following ingredients:
- water 10 l;
- liquid soap 2 l;
- carbolic acid 2 kg.
Stimulating the immune system of apple trees to protect against bark beetle
Weakened apple trees suffer from the bark beetle. The wood of a healthy tree is durable; it is more difficult for beetles to survive and reproduce there. Measures that increase the defenses of apple trees are carried out to prevent the pest.
They activate the immune system, improve the quality of photosynthesis with the help of HB-101. Stages of preventive measures:
- in the spring, along the perimeter of the trunk circle, to carry out the embedding of granules;
- after flowering, spray the crown 3 times with a solution (1 ml of product per 10 l of water), interval 7 days.
With the help of "Bogaty-Micro" fertilizer, tissues are saturated with microelements. Top dressing increases resistance to infections and pests. Apply "Rich-Micro Copper + Zinc + microelements". When preparing a solution in 10 liters of water, dissolve 1 tbsp. l. fertilizers. Processing is carried out on the sheet 4 times with an interval of 7 days.
To increase stress resistance, apple trees are watered with Gumi-30 Universal solution once every 2 weeks. The paste (100 g) is diluted in water (200 ml). The concentrate is used to prepare a working solution. For 10 liters of water add 1 tbsp. l.
It is difficult to save a tree affected by a bark beetle. Planned prophylactic treatments of the garden with modern drugs are the best way to fight the beetle.
