What are locusts most afraid of? Why? What are locusts most afraid of? How to eradicate locusts?

Why do locust plagues occur?

One of the main reasons why locusts are so easy to infest is that they are very reproductive. Locusts reproduce every three weeks and have very little requirement for a spawning ground, as long as the soil is soft, they can reproduce almost anywhere. Moreover, the eggs are all underground, so they are not easily damaged.

The occurrence of locust plagues is linked to climate change, especially drought. As the old saying goes, "Locusts rise when there is a drought". The drier environment is more conducive to locust reproduction, and drought can force locusts to migrate on a large scale.

In addition to being very reproductive, locusts are not picky eaters and a variety of plants, including crops, are their food**. And the locusts are very capable of flying, they can fly for hours on end, and the flight range can reach up to 150 kilometers. In just a week, the locusts can fly up to 1,000 kilometers away.

So, how should humanity deal with the incoming locust plague? What are locusts most afraid of?

First of all, locust plagues can be managed through the reproductive behavior of locusts. Because locusts are drought-loving, we can try to increase vegetation cover, and the wetter environment makes it difficult for locusts to lay their eggs in the soil. Therefore, the role of vegetation protection is not only to protect against wind and sand, but also to stop locust infestations.

Secondly, the locusts can be exterminated with their natural enemies. The natural enemies of locusts mainly include frogs, birds, migratory spiders and poultry, and the number of locusts can be effectively suppressed by storing or protecting the natural enemies of locusts.

In addition, the number of locusts can be controlled by sanitizing their eggs and larvae. The eggs and larvae of locusts are on the ground and can be killed by chemical control methods. Suppressing the number of locusts at the source can also prevent locust plagues.

However, both of these methods need to be prepared in advance, and they are both long-term preventive methods, for example, locusts have a limited number of natural predators, and they cannot eliminate locust plagues all at once; And if there are too many natural enemies of locusts, it may also have an impact on the ecological environment, which in turn will have a negative impact.

If the locust plague is to be curbed in the short term, the only way to kill the locusts is to adopt some powerful methods. At present, spraying pesticides by aircraft is the most powerful way to kill locusts and can kill locusts on a large scale.

The most feared of locusts should be chickens, because chickens eat this kind of insects, so they are afraid of being eaten.

Locusts are most afraid of birds, because birds feed on insects and will eat them.

It may be a bad environment, locusts fly over, naturally they want to eat food, then if there is a cold environment, etc., then the locusts will naturally not pass, and it is impossible to let themselves freeze to death to eat.

Locust plagues release large quantities of the volatile compound phenylacetonitrile, and when attacked, locusts immediately convert phenylacetonitrile into the highly toxic compound hydrocyanic acid. Therefore the locusts of the plague of locusts are poisonous. The plague of locusts is not edible.

Locusts, commonly known as "grasshoppers", belong to the order Orthoptera, including the species of grasshoppers, grasshoppers, and locusts, there are more than 10,000 species in the world, and more than 1,000 species in China, distributed in the tropical, temperate grasslands and desert areas of the world.

Locusts are most afraid of birds and frogs, ** locusts can be controlled by biological control, physical control methods, physical means can be used to intervene in the voyage mating and reproduction, and locusts can also introduce natural enemies, which are the most commonly used and most effective two methods, usually to plant more trees.

Frogs, toads, and birds, swallows, woodpeckers, owls, are all creatures that locusts are afraid of.

Locusts are most afraid of frogs, birds and lizards, and if you want to ** locusts, you have to put large numbers of frogs and birds in places where locusts are dense to prey on them.

<> locusts are afraid of natural predators such as birds, frogs, chickens, and ducks. The natural enemies of locusts mainly include frogs and birds, such as frogs, toads, sparrows, quails, terns, white-winged gulls, field wrens, swallows, etc., especially frogs, which usually live in the same environment as locusts (generally live in pits and ponds, ditches and other places with reeds and weeds), and can take the lead in restricting the reproduction of locusts.

Locusts are most afraid of frogs and birds. Basically, all frogs are natural enemies of locusts, and like locusts, low-lying areas, ponds, and ditches where weeds such as reeds and dog's tail grass grow are suitable places for frogs to survive. Birds such as white-winged gulls and wrens prey on locusts, especially swallows.

If the locust preyer is in the breeding period, they will need food more and will hunt large numbers of locusts.

The locust refers to other locusts other than the flying locust, which has many species, wide distribution, and miscellaneous diets. Due to the differences in the natural environment, the community results and hazard characteristics are different. Such as Chinese rice locusts, short-fronted negative locusts, etc.

Locusts can feed on the leaves and flowers of wheat, rice, corn, vegetables, reeds, melons and fruits, trees and weeds, and gnaw into holes in the leaves of grains, vegetables and trees.

Locusts are generally facultative diapause insects, mostly overwintering in oocysts in the soil, and only a few species such as the Japanese yellow locust and the short-legged locust overwinter as adults. The number of generations that occur in one year depends on the biological characteristics of the species, the annual effective accumulated temperature, food, light exposure and growth and development of different insect stages in different regions.
