CATDOLL : CATDOLL: Requirements for the construction of grasshopper breeding greenhouses (Standards for the construction of grasshopper breeding greenhouses)

1. How to build a locust breeding shed?

Before building the shed, eliminate all ants and mole crickets on the ground.

Methods such as capturing, trapping, and scalding can be used.

The above-mentioned insects are natural enemies of locusts. They can prey on locusts and destroy locust eggs, so these animals must never be allowed to exist in the shed.

To facilitate drainage during the rainy season, the floor of the shed should be 10-15 cm above the ground. Sandy loam is best used as it is not easy to clump and is convenient for laying and collecting eggs.

In mid-April, crops such as wheat can be planted on the ground where the shed is built to prepare food for the young locusts.

The construction area of ​​the shed is determined by the number of locusts to be raised. If you want to raise 10,000 locusts, 15 square meters is enough.

You can make use of the vacant space inside and outside the yard and build a shed support with iron wire, wooden sticks, bamboo strips, etc. according to your own conditions. Then, according to the size of the shed, use edged cloth (gauze cloth) to make a shed cover like a mosquito net, hang it on the shed, bury the bottom edge underground, leaving a door, and install a zipper on the door.

This device is designed to prevent locusts from escaping and to facilitate entry and exit for feeding management.

(It can also be built into an arched shed) The height of the shed can be 1.5-2 meters. In order to keep warm and prevent rain, plastic sheeting can be covered outside the shed.

When the temperature is high and the locusts are large (older), and are not afraid of rain, plastic sheeting is not required.

If you use natural conditions to breed locusts, the construction of the shed must be completed before the end of April, and it is best to choose a place with plenty of sunlight.

2. How many sheds can be built with a length of 80 meters and a width of 6 meters to raise grasshoppers on four acres of land?

Usually, three greenhouses can be built for one acre of land for raising grasshoppers. Generally, if one acre of land is about 200 square meters, the length of the greenhouse for raising grasshoppers is about 6 meters, so three greenhouses can be built. However, the specific construction area depends on the number of grasshoppers.

3. How big should a grasshopper shed be?

The economical materials for building grasshopper sheds are generally sticks, gauze, bamboo poles, bamboo pieces, etc. You can also use abandoned vegetable sheds, idle houses, etc. It is recommended to build an arched shed, which has strong wind resistance and simple structure. The scale of the shed can be adapted to local conditions. The length of the shed is generally not more than 15 meters, the width is not more than 6 meters, and the height is 2 meters.

4. How to manage a grasshopper shed in winter?

1.

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

2.

To 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.

The ground of the ground 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.

The area of ​​the density shed depends on the number of locusts. Generally, 600-800 adults can be raised per square meter.

5. Is it too late to build a shed in June for raising grasshoppers?

It is not too late. The best time to breed locusts in the north is from February to mid-October of the lunar calendar, while in the south, they can be raised all year round. The breeding techniques are introduced as follows:

1. Construction of locust breeding shed and preparation of shed ground. The shed ground should be 10 to 15 cm higher than the surrounding ground to facilitate drainage in the rainy season. Sandy loam is the best soil for easy egg laying and egg collection. Single-leaf crops such as wheat should be planted on the shed ground to prepare for young locusts to eat.

2. Hatching and management of locust eggs. When the temperature reaches 25 to 30 degrees Celsius, they can hatch. It is best to have more than 12 hours of light and keep the humidity at about 15%, because under such conditions, locusts are most active, like to eat, and are conducive to growth.

3. Feeding and management of locusts from the third instar to adults. At this time, it is necessary to ensure that there is sufficient food in the shed. First, if the locusts are not full, it will affect their normal growth. In addition, the strong will eat the weak and the big will eat the small.

4. Management of locusts before and after laying eggs. In order to concentrate the eggs and facilitate egg collection in the future, part of the ground in the shed can be covered with plastic cloth as an egg-laying area. The humidity in the shed is maintained at about 15%.

5. Overwintering management of locust eggs. The overwintering of locust eggs is very simple. The locust eggs in the shed can be kept overwintering in situ. After winter, some weeds can be added to the locust egg-laying area to keep warm.
