CATDOLL : CATDOLL: Do you want to grow native grasshoppers in flowers?

1. Can you raise native grasshoppers in flowers?

The soil in the flower pot will not breed grasshoppers. The grasshoppers in the soil in the flower pot are hatched from the grasshopper eggs in the pot soil. After mating, the female locust will insert the ovipositor into the soil 10cm deep and lay about 50 eggs.

2. How do locusts gather into hundreds of billions in such a short period of time?

The reason why locusts can reach a huge number of hundreds of billions in a short period of time is mainly due to the local climate and the locusts' super strong reproductive capacity. As the old saying goes, "after a severe drought, there will be a locust plague." When the land is dry to a certain extent, it is very suitable for locusts to lay eggs in large numbers. Locusts will lay a large number of eggs in a specific area that they have chosen. On land with suitable humidity, hundreds of thousands of locust eggs can be laid per square meter. After 20 days, these eggs will hatch into locusts. It is not surprising that hundreds of billions of locusts gather in some drought areas.

Locusts are very powerful. Locusts are what we call grasshoppers in rural areas. They are small-looking but powerful animals. First of all, they have strong hind legs and sharp serrated spikes on their legs, which can easily pierce people's fingers and cause bleeding. Secondly, their mouthparts are very sharp and powerful, which can gnaw animal bodies and various crops, plants, etc. They are a kind of animal with a strong feeding habit and can eat everything. Therefore, they have caused great damage to crops and plants in history. There are even records of attacks on humans in ancient books. Once they gather in large numbers, they will pose a great threat to human survival. In addition, their wings are well-developed, and they can fly a long distance before landing. Humans can't catch up with their speed at all, so it is not easy to kill them.

Locusts have a strong reproductive capacity. Each female locust can lay 50 to 100 eggs at a time, and after 21 days, the eggs will hatch into small locusts. The reproduction cycle is very short. And if the conditions are right, the female locust will lay eggs many times, so the number of locusts will form a doubling efficiency, so the locust population can grow rapidly in a short period of time.

There is an old saying about the breeding environment of locusts: "When drought is extreme, locusts will appear." In the case of long-term large-scale drought, it becomes the best season for locusts to eat and reproduce, especially when the water content in the soil is relatively low, between 10% and 20%, which is the most suitable time for them to lay eggs in the soil. In the soil of rivers and lakes where the drying area has shrunk, locusts lay particularly many eggs, and can even lay 200,000 to 400,000 eggs per square meter of soil.

First, with its super breeding ability, a magnetic locust can produce 200,000 eggs. Second, the climate is hot and there are many green plants, which are suitable for its survival. Third, the locust has a powerful mouth-digging device and is a social insect.

Locusts can gather in the tens of thousands in a short time, mainly due to the local climate and the locusts' super reproductive capacity. There is an old saying that "after a severe drought, there will be a locust plague". When the land is dry to a certain extent, it is suitable for locusts to lay eggs in large numbers. When the land humidity is suitable, locusts will choose a piece of land to lay thousands of eggs. The locust growth cycle is short, which is 20 days. After 20 days, these eggs will become locusts. Therefore, it is easy to gather thousands of locusts in a short time.

This is where exponential explosion comes in. Locusts have a very strong reproductive capacity, and a locust can lay up to 1,000 eggs in its lifetime, which means that a locust produces an average of 10 offspring a day. After exponential reproduction, the number of locusts has reached hundreds of billions.

By analyzing the differences between the gregarious and solitary types of the East Asian migratory locust, the researchers found that among the volatiles on their body surface and feces, they identified a specific volatile odor, 4-vinylbenzyl (4VA), which is more often emitted by gregarious locusts. The researchers proved that the 4VA pheromone has a strong attraction to locust populations; in field experiments, the compound can not only attract locust populations in the wild, but is also not affected by the background density of locust swarms in the natural environment. Usually, only a few locusts emit 4VA pheromones, and a large number of locusts will participate in the gathering or migration of large groups.

3. Why do some animals have two legs and some have four legs?

Grasshoppers, commonly known as locusts, are recognized pests. The suitable temperature for grasshopper development is 25-32℃, relative humidity is 85%-92%, soil moisture content is 15%-18%, and when the temperature is lower than 14℃ or higher than 40℃, grasshoppers gradually stop eating and die. When the temperature reaches 28-30℃, grasshopper eggs begin to hatch. First, prepare non-toxic soil and sawdust powder in a ratio of 1:2, with a moisture content of 20%-30%. Spread 3-5 cm of soil in a container and pat it, then spread the grasshopper eggs on the soil and cover it with about 1 cm thick mixed soil. Finally, cover the container with a layer of film and check it once every half a day. When the grasshoppers are found, use a soft brush to brush them onto the food in the shed cavity. The grasshoppers will hatch after 10-15 days. The newly unearthed grasshoppers like to eat fresh monocotyledonous plants such as wheat seedlings, corn seedlings, and weeds, but their appetite is very small. Grasshoppers aged 1 to 3 should be protected from rain. It takes about 27 to 35 days for grasshoppers to emerge from the soil and become adults. During this period, they shed their skin every 5 to 7 days, for a total of 5 times. Grasshoppers after the 5th instar gradually begin to mate and lay eggs, and each grasshopper lays about 70 to 100 eggs. In order to feed and lay eggs, grasshoppers like to live in groups and migrate.

Originally they all had four legs, but later some used the front two for other purposes, so they could only use the back two to walk.
