Cherry fly: fighting methods

The cherry fly is one of the most terrible pests of fruit trees. Such an insect lays eggs in berries of cherries and cherries. When larvae appear from eggs, they are taken for eating flesh. As a result, fruits and pits are formed on the fruits, as a result of which the fruits crumble and rot.

What does such a pest look like?

Cherry fly from the usual to distinguish is not very difficult, because it is a tiny insect about 3-5 mm in size, which has a body of dark brown color and 4 black transverse lines on transparent wings. The head, paws and shield are dark yellow in the fly, and the eyes are green.

It's time flies activity

This individual flies in the period from May to June. In the southern places - about a decade earlier. The insect begins to fly away when the earth is already warm enough, and the air temperature is above +18 degrees. Most flies are active in sunny and hot weather.

After 1-2 weeks, the cherry fly is taken for laying eggs in mature and green berries after the departure (1 egg per fruit). After 7-10 days, bright wormlike larvae appear from the eggs. For 15-20 days, they eat the flesh of berries, managing to pour 2 times for this period, then leave the fruit and pupate in the soil in a depth of 2-5 cm. During the numerous pest formation, the cherry fruit spoil by 30%, and the cherries - on 50-60%.

Development of insects

The phase of the exit of the larva of the cherry fly from the false-leg takes place in the spring. Its color is orange-gray, and it practically does not move. 4-5 hours after birth, the pest takes on a natural color, dries out, opens the wings and flies up into the foliage. In the southern conditions of the countries of Europe, the flight of insects lasts from May to July. First appear males, and after 4-5 days - already females. Special food flies are obtained from juices of ripened berries and wound extracts of leaves, which lasts 12-14 days.

Mating time

It is necessary to warm weather conditions, where the temperature is not less than +18 degrees, if below +15, then the cherry pests become less mobile, do not mate, and also do not lay eggs. If the weather is warm but cloudy, insects also stay idle and try to hide on the surface of the earth or at the bottom of the leaf plate.

Procedure of egg laying

The female lays its eggs in the ripe fruit of the forage crop. The process itself lasts 4-5 minutes. She studies the berry, then she puts eggs in her, and introduces them in a uniform movement. As soon as the ovipositor is wound up, the female subsides and, collecting the belly, displaces the egg. On unripe fruits, the place of oviposition is little noticeable, and it looks like a dot. The female lives about a month and lays up to 150 eggs.

Completion of the fly

The pupa is detected within the spoon after 5-6 days after the larva has deepened into the ground. In this arrangement, the wrecker hibernates. The predominant mass of false ectons is located within the boundaries of the projection of the crown. The formation of the pupa occurs in the soil with an increase in temperature (up to +10 degrees) and at a depth of 5 cm.

Cherry Fly: Fighting Measures

There are many ways to protect your garden from such dangerous pests as flies.

It is better to plant early varieties of cherries and cherries. The berries of such varieties are less spoiled, because by the time of their collection the insects have not time to start laying eggs. Medium and late varieties of cherries are much more damaged.

In all seasons, except for winter, it is necessary to properly loosen the ground in the trunk circle under cherry and cherry crops. This simple method can significantly reduce the number of pests.

How to deal with the cherry fly? What other methods exist? If the infection with such insects in the garden is large, then you will need to use insecticides for spraying. Do at least 2 treatments. The first spraying is performed at the beginning of the numerous departures of cherry flies, when the soil is sufficiently warmed up and the air temperature is higher than +18 degrees.

You can learn the mass outbreak of the pest by the blossoming of the acacia. At this point it is important to spray the land, where the insects come from. There is a variant of using yellow glue baits that can be hung on trees. They are also easy to make with your own hand: glue light yellow paper onto the cardboard and apply ALT glue on top of the yellow tone (it is used against mice, as well as in hunters' belts). If more than 20 individuals are trapped on the traps, this will mean that the numerous outbreaks of pests have already begun, and the struggle with the cherry fly is urgently needed.

Secondary spraying is required after 10-15 days, but no later than 14 days before harvest. To treat the cherry tree, you can use any insecticide that cures flying insects, such as Karate, Iskra, Aktara, Molniya and others. In case of repeated workings, it is necessary to change the means, so that the flies do not become addicted to them. Also do not forget to thoroughly wash berries before using them for food, regardless of the processing.

At the stage of spraying the foliage of plants, you should also work on the soil around them, because there is also a cherry fly.

If the fight against the use of chemistry is not suitable, then you can use the folk remedies. As soon as the heat comes, cherry blossom, you will need to take a sweet liquid to choose from (honey water, kvass, beer or compote), merge it into jars or trimmed plastic bottles and hang them on trees. For one plant will be enough 4-5 jars. Only better to hang them correctly throughout the crown of cherry culture. The mixture in the vessels begins to wander, and all the pests fly to this smell. It will be necessary to observe the containers, top up fresh liquid, and also to remove the caught insects.

It is necessary to try to carry out the full and rapid collection of cherry or cherry fruit whenever possible. If the process is carried out in several stages, the cherry fly will be able to spoil all other uninfected fruits. When harvesting, do not store on plants even single berries. In them also the larvae of such a pest are capable to arise.

After full harvesting, you need to remove all the carrion under the crops, eliminate it from the site or bury it half a meter deep. This method can eliminate the penetration of new larvae into the ground and their pupation there.

It will also be necessary to neutralize the cherry aphid, for it is precisely with its sweet secretions that the pests of the cherry are feeding. In parallel with the aphids it will be necessary to fight against garden ants. They also use its secretions and settle on young branches of plants. Under the trees, you can plant something that repels flies, for example, marigolds or marigolds. It will also be a good idea to spray the cherries with tobacco leaves, decoction of wormwood or diluted in water with soap (it is added in order for the liquid to adhere better to the leaves).

In early spring or late autumn, it is necessary to make a deep excavation of the soil of the near-crop circles of cultures to 20-25 cm. Thus a cherry fly in cherry or cherry can not hibernate and create pupae.
