What are the effects of natural predators and winter temperatures on locust growth?

At the beginning of 2020, the locust army, which crisscrossed about 50 kilometers, began to expand from East Africa to Asia. Locust infestations have also occurred in India and Pakistan. Locusts are everywhere in violent storms, large quantities of crops are eaten and destroyed, and there is also a food crisis in some countries in Africa.

According to statistics, the number of locusts reached 400 billion, which is 51 times the current population of the world. According to experts, if the number of locusts is not controlled, the size of the locusts will be even larger, possibly up to 200 trillion. Because the locusts have entered the breeding season.

<> why did the locust infestation happen? One of the main reasons why locusts are prone to infestation is that locusts are very felive. The locusts reproduce every three weeks and have very small spawning grounds, leaving offspring almost at any time as long as the soil is soft.

The eggs are in the ground, so they are not easily destroyed It is estimated that the female birds of locusts lay about 100 eggs per one, and there are 300,000 eggs in 1 square meter of soil. Therefore, locusts can multiply on a large scale as long as the conditions are good, and the number of individuals can increase rapidly. Depending on the serotonin, the locusts that live in a person live in swarms, and the color of the body changes from green to brown, and the damage to the place where the locusts eat and fly occurs.

The occurrence of locusts is linked to the occurrence of climate change, especially drought. There is an old saying about "dry locusts". Locusts breed in a dry environment, and drought forces locusts to move in large numbers.

Due to their high fecundity, locusts are not picky eaters, and a wide variety of plants, including crops, become feeders. The locusts are very capable of flying and can fly for hours on end, up to 150 kilometers. Locusts fly 1,000 kilometers a week.

So, how should humans respond to locust attacks? What are locusts afraid of?

First of all, the locust plague can be cured from the locust breeding action. Locusts prefer drought and can increase vegetation cover, and the relatively humid environment prevents locusts from laying eggs in the soil. Therefore, it not only protects vegetation, but also prevents sand winds and locust disasters.

Next, use the locust's natural predator to fight off the locusts. The natural enemies of locusts include frogs, birds, wandering spiders, poultry, etc., and the number of locusts can be suppressed by raising and protecting the natural enemies of locusts.

Frogs are the natural enemies of locusts; Desert locusts have a tendency to deteriorate because of the favorable climatic conditions for survival, they can destroy local food and crops, such as forage and food crops, the desert locust plague may respond to a humanitarian crisis in the Horn of Africa, in order to protect the appropriate security of livelihoods, the situation of desert yellow populations and to assist countries in their actions and eradication of this pest.

Because its reproductive ability is particularly fast, and the number of reproduction is also very large, plus the adaptability is relatively strong, so locust plagues will occur, and the natural enemy is frogs, or you can also spray some insecticides on the eggs, which can also be killed.

Frogs and chickens are natural enemies of locusts; The reason why locust plagues occur on the earth is because the reproduction ability of locusts is very strong, and many locust eggs are relatively small, and they are very well hidden, and there is no good cleaning to clean up.

Chickens, because they are afraid of chickens, and chickens will eat them as well. Because their upper food chain is gradually decreasing, there are no professional pesticides.

Chickens, because it is afraid of chickens, and chickens will eat it because of the gradual reduction of his grassroots food chain, there are no professional pesticides.

1. Locusts harm grasses, are agricultural pests, natural enemies in nature have frogs and birds, especially frogs, and locusts live in the same type of ecological environment, is the main natural enemy of locusts, in addition to lizards, spiders, praying mantis and other animals also hunt locusts.

2. Almost all frogs are the natural enemies of locusts, frogs and locusts live in the same type of ecological environment, where there are reeds, weeds in low-lying land, pits, ditches, etc., are their good places of survival, so frogs are the vanguard of restricting the locusts to live and reproduce. According to statistics, a frog can eliminate more than 10,000 pests in a summer, and a frog eats an average of 50 pests a day, up to 266, even a stupid toad can prey on nearly 10,000 pests in three months of summer. According to this calculation, an average of one frog in two square meters of crop field is enough to inhibit the survival of the hopper.

The natural enemies of locusts are frogs and birds.

Among them, because frogs and locusts live in the same type of ecological environment, they are the main natural enemies of locusts, and all low-lying land, ponds, ditches, etc., where reeds and weeds grow, are the living places of frogs. According to statistics, a frog can eliminate more than 10,000 pests in a summer, and a frog eats an average of 50 pests a day, with a maximum of 266.

Locust control measures

1. Prevention and control of natural enemies.

Birds, lizards, frogs, praying mantises, ants, beetles, insectivorous flies, etc. are all natural enemies of locusts or insects, and protecting and making full use of the natural enemies of these locusts can effectively control the occurrence of locust plagues.

2. Biological control.

By raising chickens and ducks to control locusts, the locusts hatch for about two weeks is the best time to exterminate locusts, when the locusts will not fly, and the chickens and ducks will eat at the right time.

3. Agricultural prevention and control.

Many species of locusts will eat corn, wheat, sorghum, rice, millet and other branches and do not eat soybeans, alfalfa, fruit trees, etc. Therefore, in the place where the locusts occur, you can try to use as many kinds of beans, alfalfa, fruit trees, etc. Some locust infestion sites are low-lying and can be converted into ponds for fish and shrimp farming.

The natural predators of locusts are frogs.

Frogs and locusts live in the same type of ecological environment, where there are reeds, weeds in low-lying land, ponds, ditches, etc., are their good living places, so almost all frogs are the natural enemies of locusts. According to statistics, a single frog can kill more than 10,000 pests in a summer.

Locusts damage grasses and are agricultural pests, and 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 habits of locusts

1. The feeding habits of adults and locusts are the same, both are herbivorous, and the adult stage has strong nutritional supplementation, accounting for more than 75% of the total food in a lifetime. They bite the leaves and buds of plants with chewing mouthparts into gaps and holes, and in serious cases, they eat up the leaves and buds of large areas of plants, causing major economic losses in agriculture, forestry and animal husbandry.

2. Locusts feed on plant leaves, and like to feed on reeds, barnyard grass, white grass, dogtooth grass and artemisia plants, shrimp grass and samphire seeds. Some locust species are omnivorous and also eat insect carcasses, even those of their own kind.

3. Locusts do not have the habit of swarming and migrating, they often live in one place, generally scattered in the fields and grasses, and eat grasses, so they will also have certain harm to rice and bean crops.

<> locusts generally do not hibernate. Locusts generally belong to facultative diapause insects, mostly overwinter in the oocysts in the soil, most of the adult locusts can not overwinter, only a few species such as the Japanese yellow locust and the short-legged spotted locust overwinter as adults.
