Why locust plagues tend to occur in drought years

If you are thirsty, they are thirsty, come out to find water and food by the way.

Locust plagues tend to occur in drought years because of the many benefits of arid conditions for locust reproduction, growth, development and survival. Because arid soils are relatively solid and have a moisture content of 10 to 20 percent, they are most suitable for laying eggs, so they are prone to locust infestations.

Drought causes locusts to multiply and grow rapidly, causing disasters in two ways. On the one hand, in dry years, when the water level drops, the soil becomes more solid, the water content decreases, and the ground vegetation is sparse, the number of eggs laid by locusts increases considerably, sometimes up to 4,000 5,000 eggs per square meter of soil, and there are 50 80 eggs per egg mass, or 200,000 eggs per square meter.

Locust plagues generally occur in summer, summer locusts multiply extremely quickly, after the locust plague, a large number of locusts will swallow the fields, so that the agricultural products are completely destroyed, causing serious economic losses, so that famine occurs.

Locusts are the general name of the Orthoptera locusts, locusts, commonly known as "grasshoppers", belong to the order Orthoptera, including grasshoppers, grasshoppers, and locusts, which are mostly distributed in tropical and temperate grasslands and deserts all over the world. Locust plagues often go hand in hand with severe droughts, and they move in groups from arid areas to low-lying and flood-prone areas. Therefore, there is a saying that "locusts will come when there is a drought" and "locusts will come after a long drought".

There are also many ways to prevent locust plagues, such as food control methods, locusts mainly eat millet, rice, corn, wheat, etc., then we can change the plant, such as planting soybeans and fruit trees. There is also a reduction in their habitat, the main habitat of locusts is low-lying terrain, where the grass grows and the warbler flies, and these areas can be converted into ponds for fish farming, frog farming, etc.

1. Locust plague generally occurs in summer, and locust plague refers to the catastrophe caused by locusts. In the event of a locust plague, a large number of locusts will devour the fields, completely destroying agricultural products, causing severe economic losses and famine due to food shortages.

2. Locusts are locusts of the family Locustaceae, Orthoptera insects. Colloquial name"Grasshoppers"There are more than 10,000 of them in the world. It is found in tropical and temperate meadows and deserts all over the world.

The mouthparts are hard, the forewings are narrow and tough, covered by spikes and hindwings, the hindwings are thin and suitable for flight, and the hind limbs are well developed and good at jumping.
