Rider - an insect that provides indisputable help to a person

Rider - an insect, different from othersrepresentatives of their class place laying eggs. When it comes time for reproduction, the female is looking for a victim. Having noticed a suitable larva, it thrusts an egg deposit into the body of the victim and instantly lays an egg. One attempt is not enough - and she has to attack several times, enduring an open, dangerous battle, which the hulking victim, as a rule, loses to the brisk adversary.

Insect Rider can strike and openlyliving larvae, and leading a hidden lifestyle, for example, in wood or stalks. In such cases, the female oviposition, like a drill, punches an obstacle. Some riders do not lay eggs in the victim’s body, but on its surface. The newly born larva, firmly holding itself, gnaws through the outer shell of the victim and feeds on its juices.

Rider - an insect with a thin body, with an elongatedabdomen, with a long needle-shaped ovipositor at the end. The thickness of the ovipositor is comparable to horsehair. Inside it there are three filament-like villi, during the movement of which the egg moves. A distinctive feature is the long antennae, which probes the surface and catches the slightest vibration rider (insect). The photo shows it well.

Dinocampus coccinellae is interesting(an insect rider with a size of about 4 mm, belonging to the braconid family), parasitizing on a seven-point ladybug. A laid egg begins to develop in the victim's body. Egg larva

coming out in a few days.She begins to feed on adipose and connective tissues, without affecting the internal organs of the ladybird, which does not seem to notice the changes that have occurred. This lasts about 25 days.

When it is time to leave the carrier’s body,the rider larva gnaws on the nerves going to the limb of the ladybird so that it cannot escape. Getting out of the body, the larva is located between the legs of its "canned", i.e. under her body, weaves a cocoon, which develops further. Amazingly, the ladybug is alive all this time. A pupa grows for about a week and then leaves the cocoon. Scientists at the University of Montreal proved that in every fourth case the carrier remains alive, moreover, after this incident, it returns to normal life.

Currently known about 40 thousand species of equestrians. Despite their large numbers, people rarely come across them. This is due to the fact that

insects choose habitats poorly populated,calm They vary in size (from a few millimeters to 5 cm), by habitat, by color and by behavior. They have different victims too. They can be asparagus rattles, bedbugs, cotton weevils, codling moths, and many others. But no matter how behaved and wherever the rider lived, the insect always provides its offspring with food. Considering that the overwhelming majority of their victims are insect pests of agricultural crops, destroying them, the horsemen provide undoubted assistance to man, preventing them from spreading. It is on this unusual breeding method that the biological method of controlling many pests is based.
