CATDOLL : CATDOLL: What are the conditions for grasshopper breeding (what are the requirements for grasshopper breeding)

1. What kind of soil is needed to raise grasshoppers?

Grasshoppers have the habit of flying, so they must be raised in a shed. The breeding shed should be built in a ventilated and sunny place, and the ground should be 10 cm higher than the surrounding ground for drainage. It is best to use sandy loam that is not easy to clump, so as to facilitate the picking of grasshopper eggs. Monocotyledonous plants such as wheat or corn should be planted in the breeding shed for grasshoppers to eat. Every 10,000 grasshoppers requires an area of ​​15 square meters. You can use the vacant space inside and outside the yard to build the shed support with angle irons or wooden sticks, bamboo poles, bamboo strips, etc. According to the size of the shed, use a gauze to make a shed cover, bury the bottom edge in the ground, and leave a door. Install a zipper at the door to prevent the grasshoppers from escaping.

The height of the shed is 1.5 to 2 meters, and the outside of the shed can be covered with plastic film to prevent rain and keep warm. The shed must be built before the end of April.

2. What are some basic requirements and techniques for raising grasshoppers?

1. Site selection

It is best to choose a place with good ventilation and plenty of sunlight.

2. Eliminate natural enemies

Before building a shed, you should first use methods such as capturing, trapping, and scalding to eliminate all ants, mole crickets, etc. on the ground. Because the above animals are the natural enemies of locusts, they can prey on locusts and destroy locust eggs, so these animals must not be allowed to exist in the shed.

3. Ground

The floor of the shed should be 10-15 cm higher than the surrounding ground to facilitate drainage in the rainy season. Sandy loam is the best soil, which is not easy to clump and is convenient for laying eggs and collecting eggs. The soil should not be too soft, as locusts have high requirements for laying eggs.

4. Density

The area of ​​the shed depends on the number of locusts, and generally 600-800 adult locusts can be raised per square meter.

5. Build a shed

According to your own conditions, you can use sticks and bamboo strips to build a shed frame. Then, according to the size of the shed, use gauze to make a shed cover like a mosquito net, hang it on the shed, bury the bottom edge in the ground, leave a door, and press a zipper on the door. This is to prevent locusts from escaping and facilitate feeding and management in the shed.

The height of the shed can be 1.5-2 meters. In order to keep warm or prevent rain, plastic sheets can be covered outside the shed. When the temperature is high and the locusts are large (more than three instars), they are not afraid of rain, so plastic sheets can be omitted. If natural conditions are used to breed migratory locusts, the construction of the shed must be completed before the end of April.

Grasshopper habits:

1. Incubation

The minimum temperature for hatching eggs is 17 degrees Celsius, the suitable temperature for development is between 26-32 degrees Celsius, and the highest hatching rate is when the soil moisture content is 18-22%. It usually takes 50-60 minutes for the entire egg mass to hatch from the beginning to the end, and the maximum hatching time is from 8 am to 1 pm. There are also differences in the order of emergence during the hatching process.

2. Shedding

Grasshoppers grow by molting. When they grow to a certain length and need to molt, they stop eating. Hang their bodies upside down and molt (with something to attach to). You can eat them after one hour. Locust larvae molt once every 5-7 days after they lay eggs. Strong ones molt quickly, while weak ones molt slowly. One molt is one age. From hatching to adulthood, they need to molt five times before they can become adults.

3. Social nature

First-instar nymphs often gather on plants, while second-instar nymphs prefer to gather on bare ground. The older they are, the more obvious their aggregation becomes. At first, they are small groups, but later they become large groups, crowded and overlapping with each other, and even piled up to several inches high.

4. Migration

Grasshoppers migrate not only for food, but also for the needs of reproductive physiological development. Migration can increase appetite, especially migration from eclosion to egg laying, which can increase the number and quality of eggs. Therefore, locusts should be properly disturbed after egg laying and before egg laying, so that they can fly in the shed to increase the number and quality of eggs.

3. How to breed grasshoppers that are white and yellow?

How to breed white and yellow grasshoppers:

1. Select a site and build a shed

When raising grasshoppers, you should choose a place with flat terrain, plenty of sunshine and good ventilation as the breeding site, then build a breeding shed with wooden sticks and bamboo poles, and cover it with gauze to prevent the grasshoppers from escaping, and then spread a layer of sandy soil on the ground in the shed to increase the soil's drainage and air permeability, which is conducive to the growth of grasshoppers.

2. Seed selection and stocking

There are many varieties of grasshoppers. Before raising them, you need to select suitable varieties according to the local climate and environment. The grasshoppers are required to have a complete body, be energetic, healthy and free of diseases, etc. Then they should be released at a stocking density of 600 to 800 per square meter.

3. Provide food

When raising grasshoppers, you need to feed them nutritious food once or twice a day. You can choose fresh and clean vegetable leaves, wheat, corn kernels and other plant foods, and feed them protein-rich foods to promote the growth of grasshoppers. In addition, the amount of food fed needs to be increased during the breeding period.
