There are a huge number of garden pests. In connection with the importation of seedlings and seeds from other countries, they tend to spread across countries and continents with great speed. One of the most unpleasant guests in the fields and gardens is the circus. What is it dangerous and how to get rid of it - a series of recommendations.
There are many varieties of this pest. Several hundred varieties of cicadas live in Russia, and all of them are considered pests. Some species, in particular buffalo and white cicadas, appeared relatively recently, having been imported from the countries of South America and Europe. Different types of insects can live on different types of agricultural plants - they have their own food preferences.
Whatever species the cicadas belong to, they inflict almost the same harm by eating the juices of the plants on which they inhabit. The main damage to crops:
- exhaustion of juices, which leads to a slowdown in development, a halt in development, the death of parts of plants;
- transfer of viral diseases;
- damage to shoots when laying eggs.
If cicadas are found, it is necessary to immediately begin a fight with them, since otherwise the plants may die.
Cicadas slobbering pennies
Drooling pennies are considered one of the most common types of cicadas in the country. Its habitat is in humid areas, so it reproduces well in humid summers, in greenhouses, in grass. This type of pest often affects grassy crops - strawberries, cabbage, beets, tobacco, parsley, carrots, cucumbers. She feels well on berry bushes and fruit trees.
The size of the butterfly is 5-10 mm. The color of the circus is from brown or black to yellowish-dirty. An individual lays eggs with nests, which facilitates their detection and destruction. The insect got its name due to the fact that its larvae develop in a nest of white foam, which serves to protect from the sun. The pest lays eggs in the stems of plants and petioles of leaves.
You can detect slobbery pennies by:
- the presence on the plants of accumulations of white foam;
- wrinkled and yellow leaves;
- the wrong kind of inflorescences;
- yellow spots on the leaves.
Ways to fight
Pest control measures are diverse. Pennies are very sensitive to chemicals. One of the effective means is spraying with a 30% solution of malathion. After spraying, the plants are sprinkled with wood ash 30 g each.
During flowering, the plants are treated with a solution of phosphamide. If the crop is ripening, then chemical treatment is unacceptable. In this case, you need to pay attention to the treatment of plants with the infusion of garlic - a glass of chopped garlic is diluted in 10 liters of water.
Black Point Cycade
Parasitizes on herbaceous plants, preferring ethereal. Most of all, she loves mint, catnip, sage. In the second phase of its development, it prefers labia plants. Distributed now almost everywhere.
The insect overwinters in plant debris. Appears in April-May. The butterfly itself has a size slightly larger than 3 mm and has a yellow or green color with black spots. Larvae are yellow-green in color.
Scale of damage
Larvae that suck the juices of mint leaves are especially harmful. As a result, spots appear on the leaves, then they age and fall off.
Pest control measures combine thinning, complete harvesting of plant debris on beds in the fall, and spraying with insecticides.
Green cicadas parasitize on a large number of plants, ranging from cereals to berry bushes, apple trees, pears, plums and other fruit trees. Interestingly, the insect prefers young plants and is rarely found in older gardens. This is all because it damages the thin bark. He loves, like all cicadas, humid places. The most common habitats:
- wet areas;
- unrefined landing.
The butterfly has a size of 5.5-9 mm. It is green with a yellow head and black dots on the crown. Larvae hatch from eggs laid in the fall in April-May and turn into adults by August. Cicadas prefer to lay eggs closer to the base of the trunk. In the process of egg laying, the female incisions the bark and lays eggs in wounds up to 5 mm long. Each individual deals 10-11 such damage. This may indicate the extent of the damage they cause to garden plants.
The cicada lays eggs in the autumn in the bark of young branches and trunks. It is most dangerous for young trees aged 2-3 years. In trees older than 5 years, the damage heals quickly, leaving an insignificant trace, and young plants begin to lag behind in growth and die as a result of impaired sap flow at the egg laying site.
This type of circadian is a carrier of cytosporosis. The spread of cytosporosis can lead to complete death of the garden.
It is necessary to constantly weed the garden so that there is no overgrowth of weeds, where a humid environment is formed, which is preferred for cicadas. Also, remove damaged branches and excess shoots.
Trees must be periodically sprayed with organophosphorus and pyrethrum-based insecticides. Among the chemicals can be called chlorophos, fosalon, phosphamide. Processing is carried out in the spring and in the summer. Mow the grass before processing.
Of the biological methods of control, spraying with tobacco dust and garlic tincture has proven effective.
The color of the butterflies is white, size - up to 5 mm. Egg laying takes place in August-September.
Appeared in the southern regions of our country relatively recently. Previously, she lived in trees, preferring maple, willow, dogwood and hawthorn. Now it has become one of the most dangerous pests of vineyards and field crops. The appearance of a white circadian can be determined by the appearance of brown spots on the leaves, poor growth of plants, lethargy of leaves, delayed ripening of berries.
Pest control measures are based on flushing plants in spring with 30 plus. Washing is performed before the appearance of the kidneys. In mid-May, after the appearance of the larvae, it is possible to treat the plants with Ditox, Tagore, Bi-58, and Danadim. Experienced gardeners are advised to alternate preparations and be sure to process not only grapes and fruit crops, but also garden plants - tomatoes, onions, cabbage. Apple trees are best treated with the Tzipi Plus preparation.
During ripening, treatments are not recommended. But if there are too many pests and there is a threat of crop deprivation, then you can use Akarin (980 g per 10 liters of water) or Fitoverm (2 ml per 10 liters of water).
The species was introduced from North America. She is distinguished by special gluttony. If earlier the buffalo-headed cicadas preferred wild-growing trees and settled mainly on poplar, willow, maple, now it has spread to garden crops and parasitizes on apple trees, pears, walnuts, peach trees, quinces, raspberries. In recent years, it began to affect grapes.
The adult butterfly reaches a length of 10 mm and has a green color. Eggs are laid in autumn in the branches and trunks of trees. Eggs are always laid only in living branches. Basically, the insect selects young branches and trunks with a diameter of up to 6 cm. The harm from this circus is the same as from the green one.
Control measures include weeding, harvesting and double treatment in June. When spraying plants, it is necessary to treat grass and herbaceous cultivated plants growing in the neighborhood. Well repels the insect planting under the trees of garlic and onions.
So that the plants do not breed in the garden plots, it is necessary to carry out preventive measures:
- every autumn, remove all plant debris;
- thin out plants more often to prevent moisture accumulation;
- periodically treat plants with infusions of garlic, tobacco mixed with a solution of laundry soap.
All types of cicadas are considered hazardous pests. The fight against them should be conducted systematically, from year to year. This is the only way to get rid of it in the garden.
