Cabbage fly and measures to combat it
Undoubtedly, the paramount task of every trucker is to get a rich harvest on your own private plot.
Unfortunately, on the way to this always standinsects and pests that are eager to destroy vegetable crops, reducing the work of the summer resident to zero. Special efforts in this regard are provided by the cabbage fly.
Often, the owners of suburban real estate,engaged in growing vegetables, after a while notice that the white-flesh begins to wither. Many explain this with a banal moisture deficit, so they immediately get watering hoses and water the cabbage to the maximum, confidently counting on that in a day or two the plant will come to life. However, the time passes, but the beds with the white-headed keep on being in the same, and sometimes even worse state, and then the gardeners start to wonder what's the matter, and some even experience slight panic.
And everything is explained not by lack of moisture. The crop was damaged by a cabbage fly. This is a very dangerous pest for white-blooded.
What is this insect
It should be noted that an adultthe insect in question does not cause any damage to the cabbage. Another thing - the larvae of a cabbage fly. They are the ones that destroy the white-blooded. However, not everything is as bad as it might seem at first glance. Of course, you can not save cabbage with a fly swatter or a conventional Velcro, but the means of struggle against the above pest still exist, and it's not just about chemical preparations.
It should be emphasized that the damage is caused by twoInsect species: spring cabbage fly and summer. In this case, there is no particular difference between them, except that the former is the "descendant" of the second.
Beginners should know that bothvariations of this insect can bring huge harm to cabbage beds. Do not forget that summer flies do not fly away for the winter, staying in the kitchen gardens until the spring, and with its arrival they start to give offspring, which then grows into spring "copies".
Distinctive signs of a pest
For the sake of justice, it must be said that visually the cabbage fly does not differ much from the ordinary. Nevertheless, it has a slightly smaller size and a lighter coloration than the latter.
When there are larvae
The beginning of the phase of the appearance of the larvae of spring flies isthe flowering period of the lilac, when the soil at a depth of 8 centimeters warms up to about +10 degrees Celsius. And it is this moment that is a starting point for all the ills that this insect can cause. Why? Everything is very simple. Female spring cabbage fly is ready to perform reproductive function - it lays up to 150 eggs. And it does it on the root neck of the vegetable or in the immediate vicinity of it under the lumps of the upper soil layer.
After a week and a half of eggs hatch larvae, which cause irreparable damage to the crop.
Than the cabbage fly is dangerous
Young animals require constant feeding, andthis task is realized due to the root system of the white-head. And often not only she suffers, but also leaves of plants. As a result of the destruction of the rhizome, by means of which the cabbage receives nutrients, the whole vegetable dies with time.
On average, the period of damage is from 3up to 4 weeks. This period is enough for the larva to turn into a pupa. This process takes place in close proximity to the white-headed, which was food for the larva. After 21 days after the final formation of the pupa, the second generation of the above insect is born. Moreover, with the creation of favorable conditions, a third and even fourth generation of the cabbage fly may appear. The only consolation in this case will be the fact that the harm done by individuals of recent generations will not be as significant as that of the "grandparents."
Experts to minimize damage recommend regularly to rotate vegetables.
Ways of destroying a pest
Since the cabbage fly is the worst enemy of white-collar, the most pressing question for many is how to get rid of this pest.
One of the most common ways to combatinsects, of course, is the treatment of plants with pesticides. Currently, there is a whole arsenal of drugs that effectively kill cabbage fly. You just have to go to the market or a specialized store and purchase it. Next, read the way the product is used on the label and act. You can use such drugs as "Carbophos" or "Bazudin". If you are not a supporter of the use of chemistry, then the cabbage fly, a measure of struggle with which almost everything is effective, is easily destroyed with the help of natural components.
Those who are seriously concerned about the problem of how tofight with a cabbage fly, we must remember: the best weapon is prevention. First of all, as already emphasized, do not forget about crop rotation of vegetables.
Must be disposed of outside ofyour site of a stump of a plant, after you cut off the forks. Thus, you will significantly reduce the risk of spring cabbage fly generation in the next year. Do not forget to systematically plow the land where you grew cabbage. This will destroy most of the larvae that have already pupated.
Certainly, a formidable opponent is a cabbage fly. Of course, the methods of combating this insect are not limited to one prophylaxis. What else can you do?
Alternative control measures
Some experts recommend selectionsoil from the plant before the procedure of hilling. To do this, remove the top layer of the earth, located within a radius of 10-15 cm from the plant, and to this place bring the soil from another place within the boundaries of your garden (for example, from the territory where you planted onions or carrots last year).
So, we found out that the cabbage fly is still vulnerable. Control measures against this insect can be successfully combined and combined.
A certain part of specialists in the fight againstinsects advise to enclose each cabbage fork with paper. First you have to prepare the paper from the paper, the diameter of which is 15 centimeters. In the middle, you need to cut a hole for the cabbage stalk, after which we make a cut along the radius of the circle to its center. The next step is to put the workpiece on the stem and lay it on the soil. Thus, you will do your best to ensure that the offspring of the cabbage fly is not on the stem of the seedling or the soil near it, but on a paper structure. Naturally, the eggs on the circles will soon die, never turning into larvae.
Another part of the experienced truck farmers effectively destroys the pest by treating the plant with naphthalene or tobacco dust. Some use a color trap, treated with special glue.
