The locust is a winged insect that usually lives and moves in large groups (herds). It looks like a grasshopper, however, it differs in the size of the torso and mustache.

This pest has always been dangerous for agricultural crops, since in a short period of time it can eat plants almost at the root, especially for such a species as the Asian migratory.

What do locusts eat?

When forming a huge flock, the insect can eat all the vegetation that it can meet on its way. The total weight of the plants eaten per day is equal to the own weight of the pest, but an average flock destroys 3-4 tons of greenery daily.

In addition, the diet expands over the years - the older the insect, the more omnivorous it becomes.

Maybe have:

    • Reed and reed thickets along the banks of rivers, ponds, lakes, swamps;
    • Any cereals - wheat, oats, corn, rye, barley, millet, sorghum and others. With less appetite, the insect destroys flax, buckwheat, hemp;
    • Vegetable crops - beans, beans, soybeans, beetroot and sugar beets, potatoes and others;

  • Orchards - the pest can eat both the leaves and fruits of plums, cherries, peaches, pears, and gnaw the bark of young trees;
  • Planting grapes - berries, petioles, grape leaves are eaten;
  • Cabbage, melons and gourds - pumpkins, melons, watermelons, sunflower planting;
  • Separate trees, shrubs, grass, including whole forests.

During a locust invasion of a settlement or village, reed or thatched roofs and wooden household items were often destroyed. In arid areas, the pest can feed on any dried grass and leaves.

How does the oral apparatus work?

The locust mouthpiece is gnawing, it is intended for feeding on solid food. This type is primordial, and other forms of the structure of the mouth in other insects come from it. The gnawing apparatus contains the most complete set of elements - the upper and lower lips, and two pairs of upper and lower jaws.

With the help of the upper lip, the insect determines the suitability of the eaten object for consumption. The upper jaws move horizontally, bite off a small piece and grind it into smaller pieces. Strongly mobile the lower jaws push the crushed food into the esophagus.

In addition to the function of feeding, the upper and lower jaws can be used by insects for protection in a fight with the enemy.

Do locusts bite?

It is very often confused with grasshoppers. With a similar appearance, they also have cardinal differences:

  • The grasshopper has a long mustache that helps it find its prey (the locust has a short mustache);
  • The grasshopper is predominantly nocturnal (the locust is a daytime inhabitant).

Since the grasshopper is a predator, it is he who can bite a person quite painfully, very often to the point of blood, with the introduction of a burning composition into the wound.

Do locusts have teeth? This insect has a mouth no teeth - it is herbivorous, not predatory. She will not specifically attack a person and try to harm him.

Nonetheless the jaws are strong enough, necessary for quick nibbling of pieces from hard plants. And when the self-preservation instinct is triggered, the pest can sensitively "pinch" the skin. If this happens, it is recommended to treat the bite site with hydrogen peroxide, iodine.

Locust also cannot sting - stings are not provided for by nature.

This is a huge disaster for all farmers and gardeners. She moves in large flocks, multiplies quickly and feeds on any vegetation that is available to her.

Not only crops can be destroyed, but also trees, shrubs, reed and thatched roofs, and wooden furniture. The locust has a gnawing mouth apparatus designed to bite off and grind solid food. She cannot bite or sting.
