Aphids on carrots
Carrots are one of the most common root crops among gardeners. Carrot fruits are juicy and healthy due to their high carotene content. To obtain a high-quality harvest, it is necessary to protect plants during the growing season from the attack of various pests and diseases. One of the worst pests for carrots is aphids. It is very important for summer residents to know how to deal with these insects, because they do not just eat your plantings, but can be carriers of various diseases.
Varieties of aphids
Almost in all places where they are engaged in agriculture, they know about small pests - aphids. Aphids not only eat carrots, but also spoil trees, flowers and other garden crops. The pest multiplies exponentially. Carrots are attacked by three main types of aphids, how they differ, we will find out later.
Insect pest - carrot aphid
The most common carrot aphid, there are individuals, both with wings and a demon. She prefers to settle on the umbrella. Insects with wings can fly and capture new territories to destroy plants, without wings they take an active part in reproduction already on the attacked plant. On average, the size of aphids is about one and a half millimeters.
The first individuals appear with the onset of warming; the eggs spent the whole winter on unharvested green shoots or on wild roots. The mother is green with a blue head, no wings. In the spring, the aphid finds a suitable plant and reproduces asexually. Virgin individuals begin to appear, they also do not have wings. They give birth to the main offspring, with wings and without wings.
Individuals with wings
Insects with wings are needed to spread over other plants, they fly from plant to plant. Such insects have to find the places where the carrot grows, the lower parts of the carrot tops fall under the attack. The head and chest are black, the abdomen is blue. They also destroy plants, feed on their sap.
In the autumn, a full-bodied generation ripens. With the help of it, bisexual individuals are born asexually, they can reproduce sexually. Fertilized eggs are laid by females in the tops or on wild plants.
Insect pest - hawthorn aphid
The next type of aphid is the hawthorn aphid. Such aphids have two owners, the first owner is a hawthorn bush, the insect lives there in winter. The second owner is already directly carrot plantings, aphids fly to them at the beginning of summer.
Description of appearance
Usually, an adult is no more than two millimeters in length, has a black, greenish or brown body. Each stage of the life period is distinguished by the morphological structure of the body.
During the season, asexual individuals that do not have wings appear from the main individual, they are already giving birth to the next generation - cloned females. Female clones are the generation that gives birth to live individuals, during this period there are most aphids. About twenty such "chains" can change over the spring and summer.
In the summer, winged, but sexless individuals are born. Such individuals begin to appear if insects torture the plant on which they live too much. Insects begin to search for new, not yet touched plants to organize new colonies, either carrots or hawthorns.
In the onset of autumn, detachments of winged stripes appear, their main task is to return to the hawthorn and give rise to new individuals. The new generation consists of winged males and females without wings. The winter of the laid female eggs passes in the hawthorn and then all generations repeat again.
Insect pest - willow-carrot aphid
The final type of carrot pest living on the edges of the leaves is the willow-carrot aphid. Individuals also come with and without wings. Insects without wings have a green body, small whiskers (they are half the size of the body), the average size is about three millimeters. Wintering of this species takes place in the bark of willows and on various buds, then they hatch in the spring. At first, individuals live on willow and absorb the juices of buds and young leaves.
Individuals with wings
It is the winged individuals that fly to carrots, also to dill and parsnips. The whole body is usually green and there are faint specks on the sides. During the warm season, a certain number of generations of aphids change. If individuals return to willows closer to autumn, the last generation of females will appear from them. These females reproduce and lay eggs that will endure the winter.
Importance of processing
It is very important to observe the plants and start processing from them in a timely manner, then it will be much more difficult to do this. For different types of aphids, the same control methods remain.
How to determine the presence of aphids and how they can cause damage
Where do carrot aphids live?
Habitats of carrot aphids:
1) the lower surfaces of the leaves;
The most favorable weather for rapid and multiple breeding is hot and dry. During rains and cold snaps, aphids reproduce much more slowly. Aphids quickly capture plants in spring and adapt to life on them.
The root crop itself is aphid, as food is not interesting, they feed on the juice of the tops. If you notice a thin whitish film on the leaves - the first sign of the appearance of insects.
What can cause aphids on carrots
Basically, aphids enter the plant through ants, so a large number of them next to carrots will not be a favorable neighborhood.
Evidence of presence
On the petiole, and especially on the backs of the leaves, you can easily see hordes of aphids. Individuals are close to each other.
Where is it better not to plant carrots
It is better not to plant carrots in the immediate vicinity of good-smelling trees: 1) linden; 2) bird cherry; and 3) viburnum, they can lure insects. Also, aphids are impressed by the presence of: 1) petunias; 2) begonias; 3) nasturtium; 4) poppies; 5) mallow; 6) cosmic; and 7) glue. Of course, the aphids will not mind sucking the juices out of them. In the presence of such plants nearby, reproduction will accelerate.
What harm can it do
In fact, the main harm from aphids is infection with possible diseases that are carried by insects. An important consequence is the wilting of plants due to the fact that aphids on carrots suck their juice. Often because of this, the root crop cannot be fully formed. The leaves often change and change color, and the very tops on young shoots can become hard.
What happens to the plant
The breathing process becomes difficult due to lack of air, this happens "due to" the formation of a film on the leaves.These secretions are also a good breeding ground for fungal infections; they cover the leaves with an impenetrable film. Because of the same layer, photosynthesis cannot work at full strength and this is already one factor due to which the condition of carrots worsens.
With the right choice of aphid control method, you will overcome. Sooner or later, many are faced with the problem of pests, one must be prepared to repel the attacks of harmful insects.
