What crops the bug damages the harmful turtle and how to get rid of it
The harmful turtle is one of the most dangerous and malicious pests of agricultural fields, causing great concern to agronomists and gardeners. The bug is a harmful turtle that damages not only cereal crops, but also garden crops. The fight against the pest must be started immediately after its appearance, otherwise the crop can be completely destroyed.
Bug harmful turtle – description of the pest
The bug the turtle is an insect from the order of Hemiptera, a “representative” of the family of scutellids. It is the shield bugs that are biological pests of cereal crops. At the same time, the harmfulness threshold is 1 insect per 1 m².
The main features of the harmful turtle:
- The body is flat and rounded, up to 9-15 mm long and 8-10 mm wide.
- The front pair of wings has a special structure, which became the identification mark of the harmful turtle and gave it its name. They have a “turtle” color with dark spots and stains.
- The body of the insect is covered with a tough chitinous shell that looks like a tortoise shell..
- The bug has 3 pairs of legs that allow it to move long distances and swim.
- The oral apparatus looks like a thin proboscis, consisting of sharp bristles and long filiform antennae on the sides..
The bug turtle can have a different color – yellowish-gray, brown or red-brown.
Harmful turtle bugs reproduce bisexually and reproduce by incomplete transformation, skipping the pupa stage. Females attach eggs to the back of leaves and on plant stems.
The life cycle of an insect does not exceed 30-35 days, during which females lay up to 42 eggs.
After 10-25 days, young individuals – nymphs – hatch from the eggs. Over the next 30-45 days, the nymphs molt 5 times. It is the nymphs of the bug, the harmful turtle, that damage the grains of cereals, stems and foliage of plants.
With the onset of winter cold weather, the insect hibernates. Bedbugs hibernate under fallen leaves in gardens, in private plots, in forest belts, stumps and felled trees. Pests wake up in the first half of April, when a warm air temperature of at least + 15 ° С is established. A few days later, insects go in search of food, flying distances of up to 100 km.
What crops the bug damages the harmful turtle most often
Bugs, a harmful turtle, damage cereal crops, as well as plants growing in vegetable gardens and orchards. Insects attach at the base of the stems – it is there that the processes of sap flow are most active. Gradually, the pest moves up the stem, feeding on juicy and soft leaf plates.
The bug the turtle pierces the stem or leaf with a sharp proboscis, injecting digestive enzymes inside. They cause decomposition processes inside the plant and its rapid wilting. Such a culture can no longer bear fruit, since the process of sap flow is disrupted and quickly dies..
What the harmful bug damages the bug:
- spring and winter wheat;
Among garden crops, raspberry bushes, tomatoes, bell peppers, cucumbers, beets most often suffer from the invasion of bedbugs. In the absence of such food sources, pests can infect garden trees..
A bug a turtle in an apartment can only be by chance, especially this insect does not seek to penetrate a person’s dwelling.
It can enter the house only by chance – along with the brought vegetables, fruits or herbs. Also, insects can accidentally fly into the apartment through an open window. A harmful turtle does not pose any danger to humans. She cannot bite through human skin, since her mouth apparatus is not designed for this..
Fighting the bug harmful turtle
Given the extremely fast rate of reproduction and the ability to destroy the entire crop, the control of the turtle bug should begin immediately after the first pests are identified. For this, agrotechnical, chemical and folk methods of struggle are used, aimed at reducing the number and limiting the feeding of larvae, as well as the destruction of adults..
Many farmers and agronomists choose agrotechnical methods of dealing with bedbugs with a harmful turtle. They are safe for plants and future crops, and also allow you to get rid of pests without the use of insecticides..
Basic agrotechnical methods of control:
- Planting plants deep enough.
- Careful selection of planting material.
- Tight landings. The tighter the crops, the lower the risk of a turtle bug, as it will not have enough moisture and light.
- Timely feeding of crops – bugs do not tolerate nitrogen-containing fertilizers, especially ammonium nitrate.
To prevent the appearance of pests, early sowing of cereal crops is desirable. Thanks to this, the crop can be harvested before the turtle bug larvae appear..
Natural enemies can be involved in pest control. The harmful turtle is afraid of centipedes, ants, and hedgehogs. Therefore, if these insects appear in the garden, the risk of attack by a harmful turtle is reduced..
Among the methods of how to deal with a turtle in trees, insecticidal preparations from the group of pyrethroids, nitromethylenes and organophosphates are most effective..
The most effective drugs include:
Insecticidal preparations give a quick result, as the fruits and grains are exposed to chemicals. The undoubted advantage of chemicals is the ability to effectively process a large area in a short period of time..
The composition of chemicals includes neurotoxic poisons that block receptor connections in the body of insects, leading to their rapid paralysis and death. They are dangerous to the human body, therefore, processing should be carried out only with the use of safety equipment..
Biological products are less hazardous than pesticides. They contain components of biogenic origin, which are analogs of natural compounds contained in bacteria and other living organisms..
Effective biological products:
- Eforia KS;
- Kinmix KE.
When using biological preparations, it must be borne in mind that in the body of the bug the turtle quickly develops resistance to toxins. That is why for the complete destruction of pests, you need to change the drugs used at least once a season..
The bug is a harmful turtle – one of the most dangerous and malicious pests of cereals, horticultural and horticultural crops, causing significant damage to the crop. Insect control measures must be started immediately, otherwise a fast-growing colony of bedbugs can lead to the complete destruction of the crop.
