Aphid insect. The lifestyle and habitat of aphids

If we classify insect pests and useful, the second will be much greater. Too much in the nature of such parasitic creatures that like to make money at someone else’s expense. It is to such insects aphids belongs.

This tiny insect can bring incredible damage to large plots of various plantings, as well as all houseplants. For many gardeners aphids-a pest that creates an incredible problem, and sometimes global damage.


These insects are so prolific that their appearance in small quantity for a short time turns green plantation colonies of aphids, get rid of that is not as easy as it may seem to some to be at first glance.

In the unit the Homoptera, which include these insects, there are about 3500 species. Each of them has its own characteristics. What harmful aphids? Her large colonies feed on the SAP of plants, depriving them thus of vital forces between them and spreading virus diseases.

From the parasitism of the aphid plants have significantly slowed growth. If fruit plants, they begin to bear fruit and then stop to give birth. For example, a large number of aphids, which appeared in the Apple orchard, just a month can cause the garden to wither.

The growth of shoots and trees is reduced in 2 times. The aphid itself is not out there where she is, than to profit. This means that a sad end for all living spaces are inevitable. Starting their activities, these small parasitic insects from the first month of spring. And they continue until late autumn.

From the actions of aphids in plants runs out of vitality, they can get a variety of viral diseases transmitted by insects. In addition, plants may experience various abnormalities in development, for example, growths on the root system.

Characteristics and habitat

These insects have a great ability to blend in. Shades takes on the color of plants on which they feed. Green aphids on apples, grapes, house plants, aphids are black in color is observed on cherries, currants and red gooseberries eats the aphid, the insect is yellow with a green tint is parasitic on cucumbers and melons.


In most cases, the aphid has an oval shape. Sometimes there are these insects in the form of a drop, sphere, egg or ellipse. Size aphids are tiny, but to the naked eye it can still be considered. It reaches a length of up to 0.7 mm. In rare cases, can be found among these giants, with the size of about 7 mm.

This insect is among those who eat plant food. They are equipped with a special proboscis, piercing the plant tissue and pull out all the juice. It’s amazing how quickly they can multiply, this is one of the most important features of the aphid. Insects come in from the porch and without.

In nature, there is an interesting circuit to which it is impossible not to pay attention. Aphids from plant SAP gets important for the development and life of the protein compounds and amino acids. Allocated in the process of recycling these nutrients suspension sticky consistency, which is a favorite food of flies and ants.

Scientists have observed strange facts cooperation aphids with ants, which are trying to protect their nurses from possible trouble. Moreover, the ants carry aphids from one plant to another, and their females even hide in my house from the winter chill and frost. After this observation has to contend not only with aphids but also with their «guardians».

The body of the aphid is not protected by a shell, as in many insects, it is soft and is exposed to outside, aphids can be easily crushed. The insect’s long limbs, but it does not mean that aphids are able to move quickly. She does it slowly.

Wingless insects differ visually from the cruise. At first, the proboscis is longer and thicker. From the winged aphids have two pairs of wings, with which it is easily moved in space.


Winged aphids have a slightly different rhythm of life from wingless. In the autumn period is the time of oviposition of the winged fertilized females. Eggs are laid not in all places.

The preference of insects giving wild radish, cress, cabbage stalk. Throughout the winter the eggs are in these plants. With the arrival of spring they turn into larvae, which develop and survive at the expense of cell SAP of green space.

Then they molt after aphids reproduce. By the way, they do it without sex differences. As a result, the light appears a large number of insect larvae. Scientists who observed this process, I was horrified. Within one month one female can produce about 10,000 insects.

Wingless aphids leads a virtually sedentary lifestyle. From birth till his last days, they are at the same place. Using their proboscises aphid feeds on plant SAP gets all the important components of life and well developed.

If not the fight and not try to destroy it, it will continue to parasitize, reproduce, and cause harm to vegetation. Moreover, the presence of males it is absolutely not necessary.

Approximately in the middle of summer in the crowd of wingless females begin to appear periodically winged their representatives. They, in turn, without any problems be moved to the new lands of greenery and with great pleasure are improving there.

Winged aphids plays an important role in the continuation of their kind. Because aphids, which is not able to move at a time can exhaust the food supply and it dies. Migratory aphids immediately at the new location just forms huge colonies of such creatures.


The end of summer is significant for these insects because of them finally appear heterosexual beings, between which the mating occurs. With the parishes of winter frosts the insects die, leaving behind eggs, which with the arrival of spring will be held the same life cycle and die in the winter.

How to determine the appearance of aphids on the plant? If the green areas are gradually beginning to lose its attractive appearance, it is necessary to examine them.

Usually apterous aphids under the leaves of plants. Increased in size of the colony without any hesitation and fear completely cover all the green areas. Leaves after a brief contact with these insects dry out, and after twisting and all die.

All fruit trees are much less bring the harvest. Sometimes their fruit crumble even before its maturation. Shoots and stems of plants bend. In addition, all damaged plants are covered by the sweet secretions of aphids, which gardeners call honeydew dew.

Not eaten honeydew ants causes the plant to infection of sooty fungus. This suggests that the emergence of a large number of ants in the frequent cases indicates that somewhere near the aphid parasite, though not yet seen the fruits of its actions.

The most suitable for these pests, the climate is humid and warm. Only in such conditions it is possible the mass reproduction of aphids. It can be found in many areas, ranging from Europe to Siberia.

Aphids-insect prefers to stay in large colonies. Its favorite habitat on the green leaves and young shoots. Companions throughout their lives are the ants. This tandem brings benefits to both of them. Aphids are protected ant that eats her honey dew.


It is interesting to observe their communication. The ant approaches the aphid and after a gentle tickling gets a portion of sweet liquid. This droplet is passed along the chain to the house of the ant, which often finds shelter aphids in the winter. Do aphids have enemies from which the ant tries her carefully protected. Ladybugs and lacewing can destroy colonies of aphids.

Food aphids

For normal existence and development of the aphid requires amino acids that exist in plants. It is an omnivorous insect not shrink from any vegetation. However many of them have their own preferences in food. For example, grape aphids not visit the Apple orchards and eat their vegetation. Conversely, not found in nature Apple aphids, sitting on the grapes.

The reproduction and lifespan of aphids

There are aphids, which deals with the deposition of eggs. But there are such insects are called viviparous. Parthenogenesis is inherent in many species of these insect pests. Some of the aphids come into the light with wings and heterosexual. Others, on the contrary.


A big role in procreation play aphids winged individuals, which does not allow a death like his hunger, and move into new territory in search of food for themselves.

Scientists noticed that the winged aphid often appears in the case if, for example, on the plot there is a large amount of ladybugs. The whole process is very complicated. But in short try to explain it all is as follows.

Ladybug finds its victim and eats it. As a result, the aphids produced from a specific aromatic substance, which collects all aphids in the colony. From this comes the panic. In such a panic give birth to more aphids with wings. This insect is not long-lived. Live louse can, several days and months. With the onset of frost, it all dies.
