CATDOLL : CATDOLL: Beanworm breeding technology and guidance (Beanworm breeding process)

1. Xuzhen bean worm breeding technology?

1. Set up breeding fields

Find a field with high terrain, sunny and windproof, well-drained and ventilated as a breeding field. Set up a breeding field about 3 meters long and wide. Then surround the field with a fine net, generally more than 1 meter high. If it is less than 1 meter, it is easy for the slugs to escape. After selecting the land, prepare the land at the end of May, and plant soybeans in June after fertilizing.

2. Seed collection

You can go to the wild to catch mature larvae and then raise them in the field. About 80 wild larvae should be raised in 1 square meter of breeding field. Then the larvae can feed on the soybeans planted, and after a period of feeding, they will begin to hibernate in the soil in September. Then cut the soybeans, do not plow, and maintain the environment. You can also directly buy larvae and raise them.

3. Pupation, egg laying, hatching

In April, the temperature rises and the insects pupate in the soil. During the pupation period, soybeans should be planted again. In June, they will emerge as adults and then start to lay eggs. The eggs are usually laid on the back of soybean leaves. Adults lay eggs three hours after mating. During this period, they should be prevented from flying away from the breeding fields. An adult insect lays more than 200 eggs at a time. In July, most of the eggs will hatch.

4. Feeding

Plant soybeans for food before pupation. Larvae in a 9-square-meter breeding field need one or two acres of bean leaves for feeding during the entire larval period. The hatched larvae can be raised indoors, just like raising silkworms, in separate pools, covered with gauze to prevent escape, and fresh bean leaves can be picked and spread for feeding. The amount of feeding leaves increases as the larvae age increases.

5. Seed saving

In September, we need to select strong and mature larvae and put them in the breeding field to let them overwinter, and then pupate and hatch new larvae in the next year. This is to save the insect seeds for the next year, and it is necessary to save seeds in this way every year.

To breed bean worms, you need to stay away from the soybeans grown by others and breed them in an isolated area. Breeding bean worms is a new project, which is very suitable for breeding in rural areas and invested as a wealth-making project. At present, the number of breeding is small, but the market demand is huge. Therefore, it is believed that we can get better economic benefits by targeting the wealth-making project.

3. I want to know how to breed bean caterpillars?

If you only want to raise bean worms (bean hawk moths), you don't need to fertilize; if you want to take both into account, then fertilization is still necessary. The following are some techniques: Stocking period: According to field surveys and observations, local bean moth larvae mostly occur from mid-to-late July to early August, and gradually enter the soil to hibernate from the end of August to early September. Because from the perspective of larval individual development, stocking in advance is conducive to the larvae's feeding growth and increasing the individual insect weight. If it is too late, it cannot develop to the 5th instar, the insect body is small, and the larval yield is affected. Comprehensive analysis shows that it is appropriate to stock bean hawk moth larvae in the early soybean pod setting period from late July to early August, and the early ones can be stocked in advance in early and mid-July. At this time, the soybean leaves are growing vigorously and the bean leaves are fully expanded. The l-2 instar larvae that are accessed are small and have little food intake, which has little effect on soybean growth, thereby minimizing the mutual influence between bean pod growth and larval growth and obtaining the greatest comprehensive benefit. Selection of soybean varieties: In order to provide as much bean leaf food as possible, soybean varieties should be selected with tall plants, vigorous growth, many and large leaves and unlimited pod-forming habits, which can increase the amount of insects raised and increase the larval yield per unit area. According to the growth of soybeans, the amount of insects raised can be specifically mastered: soybean fields with good growth and lush branches and leaves can be appropriately raised, otherwise the amount of stocking should be reduced. If too much is stocked, the total amount of insects will increase, but due to lack of food, the insect body is poorly developed, and the economic benefits are poor. From this experiment, it is appropriate to stock 10-15 1-2 instar larvae per square meter. Influence of natural enemies: Under field conditions outside the cage, bean moth larvae will also be parasitized and fed by parasitic flies, mantises, frogs and birds, thereby affecting the yield of larvae. According to field observations, under field conditions, the feeding of natural enemies on bean moth larvae accounts for about 5%-10% of the total amount of insects raised, and the parasitism and feeding rate of 1-3 instar larvae is slightly higher than that of 4-5 instar larvae. The average loss rate is about 80%. Therefore, the stocking amount of young larvae can be appropriately increased under the field strips. Comprehensive benefits: If 10 bean hawk moth larvae are stocked per square meter, 6,670 insects can be obtained per 667m2, with an average single insect weight of 8.15g, and a total of 54.36kg of insects can be obtained. If the natural enemy loss is 8%, the loss of insect weight is 4.35kg, and the actual insect weight is about 50kg. According to the current market price of 10 yuan/kg, the income from raising insects per 667m2 is about 500 yuan. The loss of soybean yield is about 6%. If calculated at 200kg/667m2, the loss of soybeans is 12kg. According to the market price of 2.2 yuan/kg, the loss of soybeans is 26.4 yuan/667m2. Combining the two, the soybean field where bean hawk moth is raised has an increase of 500-26.4=473.6 yuan per 667m2 compared with the ordinary soybean field. In addition, by raising hornworm larvae in soybean fields, there is no need to spray pesticides to control hornworms, which can reduce the cost of medicines and produce soybeans without pesticide pollution, which is beneficial to improving people's health level and provides a new idea and way for the adjustment of agricultural industrial structure.

4. What is the whole process of bean worm breeding?

If you want to grow bean worms, you must first build a greenhouse in a relatively high place with good drainage. When choosing bean worms, you must choose those that are about to be buried in the soil or have already been buried in the soil. Then you need to deep plow and shallow harrow the soil in the greenhouse and make ridges after leveling. The film and net should be buried deep in the soil, with a depth of 15-20cm. Put the selected bean worms in the ridges and cover them with soil. The depth of covering should be 10-15cm.

1. Bean Dan breeding technology

1. Site selection

Taking the cultivation of bean worms in greenhouses as an example, the greenhouses are generally built in places with relatively high terrain and good drainage.

2. Seed selection

(1) When selecting the source of bean worms, you must choose bean worms that are about to be buried in the soil or have already been buried in the soil as the source of seeds.

(2) In terms of characteristics, it is generally necessary to select beans with a ring-shaped or straight stick-shaped shape. Do not choose beans with strong vitality as seed sources.

3. Breeding management

(1) Land: The soil in the greenhouse needs to be deeply plowed, shallowly harrowed, and leveled before making ridges.

(2) Covering with film and net: Generally, the film and net should be buried deep in the soil, at a depth of 15-20 cm, to prevent the bean worms from escaping.

(3) Depth of soil covering for bean worms: Place the selected bean worms in the bed and cover them with soil. The appropriate depth of soil covering is 10-15 cm. If the soil covering is too thick or too thin, it will affect the growth of bean worms.

(4) Soil nutrients: After the bean worms enter the soil, the moisture content in the soil must be maintained. When the soil moisture is insufficient, water should be sprayed in time to replenish it, but there should be no stagnant water in the soil.

(5) Temperature: In winter, the temperature of the greenhouse should be maintained at around 10-25°C; in March and April, the temperature should be maintained at around 25°C; when the bean sprouts are about to enter the pupation period, the temperature of the greenhouse needs to be above 25°C.

4. Prevent and control natural enemies

(1) Generally, during the winter, the main control measures are ants and other natural enemies. Ants can be killed by luring them with cooked meat, while other natural enemies can be killed by mixing wheat bran with agricultural trichlorfon.

(2) In the first 20 days of soybean emergence and after soybean planting, natural enemies such as blind bugs, ladybugs, and mantises need to be controlled. When using pesticides, be careful not to use pesticides that soybeans are sensitive to.

5. Induce Bean Dan to lay eggs

(1) Because the bean pods lay eggs irregularly and in large numbers both in the shed and on the ground, it is necessary to induce the bean pods to lay eggs.

(2) During the bean larvae's egg-laying period, a sweet and sour solution should be evenly sprayed on the bean leaves to allow the bean larvae to lay their eggs on the leaves, which can increase the survival rate of the larvae.

6. Planting soybeans

(1) Choosing soybean varieties: Choose soybean varieties with high protein content, tall plants and large leaves, such as Dongxin No. 3.

(2) Sowing period: The sowing period of soybeans should be determined according to the emergence and egg-laying period of soybeans. Generally, soybeans should be sown 40 to 50 days before the emergence and egg-laying period.

(3) Planting density: The soybean planting density is 5,000-8,000 plants per mu, and the row spacing is not less than 67 cm.

(4) Managing soybeans: Before soybeans bloom, regularly inspect the soybean fields to ensure ventilation and light penetration between the rows, increase the number of green leaves, and make the leaves larger, thicker, and of higher quality.

7. Feeding and management

(1) Because adult bean moths lay eggs unevenly, when the larvae are in the 2nd or 3rd instar, it is necessary to sparsely plant the leaves so that the larvae can eat enough leaves in time.

(2) At the same time, the larvae’s exercise volume should be reduced to lower the nutrient consumption in the body.

8. Harvesting Bean Dan

(1) Considering the quality of the bean curd, it is generally necessary to harvest it in time before it enters the soil at the fifth age.

(2) Considering the market situation, the bean larvae can be harvested when they are in the fourth instar.

(3) Generally, when harvesting, you should choose larvae with flat heads. Larvae with pointed heads have low nutrition and are not edible.

9. Things to note when raising the next batch of bean curd

(1) Before breeding the next batch of red beans, the greenhouse should change the crop rotation to reduce the base number of insect pests, which is conducive to breeding the next batch of red beans.

(2) If the crop rotation cannot be changed in time, it is also necessary to remove all the films and nylon nets in the greenhouse, then deep plow and water, and repel insects to reduce the pest coefficient.

5. What are the techniques for breeding bean worms in greenhouses?

Kaiyi Internet of Things provides modern agricultural services. Let me answer this question.

What are the things worth paying attention to in the greenhouse breeding technology of bean worms?

(1) Choice of greenhouse

When using a greenhouse or plastic shed to breed bean moth, the site should be selected at a relatively high terrain, and the area around the greenhouse should be conducive to drainage.

(2) Leveling and making ridges

The soil in the greenhouse should be deeply plowed, shallowly harrowed, and leveled before making ridges.

(3) Select the source of bean worms

The key to artificial breeding of bean worms is to improve the survival rate of bean worms. The survival rate of unselected bean worms buried in the soil is only 5% to 10%. If selection and rejuvenation are carried out, the survival rate of bean worms can be increased to more than 85%. In the selection of seeds, bean worms that are about to be buried or have been buried in the soil must be selected as seed sources. From the characteristics, it is better to select bean worms with a ring or straight rod shape, and bean worms with strong vitality cannot be selected as seed sources.

(4) The edge of the shed where the upper film net is placed should be buried at least 15 to 20 cm deep to prevent bean worms from escaping.

(5) Soil coverage depth for bean worms

The selected bean worms are placed in the beds inside the shed, and the depth of soil covering should be 10 to 15 cm. If the soil is too thick, the soil temperature will be low and the development and pupation will be slow; if the soil is too shallow, the soil surface temperature will be too high and the surface moisture will easily evaporate and run away, making it easy for the bean worms to drill out and run to the surface, reducing the moisture in their bodies and causing their death.

(6) Soil nutrients

The soil moisture should be maintained at an appropriate level when bean worms are buried in the soil to ensure the water requirements of the bean worms' bodies. If the soil moisture is insufficient, water should be sprayed in time to replenish it, but the soil should not be waterlogged.

(7) Temperature requirements

The temperature in winter should be kept at around 10~25℃. In principle, the temperature in March and April should be kept at around 25℃. When the emergence period is approaching, the temperature in the greenhouse should be kept above 25℃, which is conducive to the emergence of bean worms.

(8) Preventing bean insects from being harmed by their natural enemies

There are many natural enemies of bean moths. During the winter, we mainly control ants and other natural enemies. Ants can be killed by luring with cooked meat, and other natural enemies can be killed by luring with wheat bran (wheat bran) mixed with agricultural trichlorfon. After soybean planting, we control blind bugs, ladybugs, and mantises 20 days before the emergence of bean moths. When using pesticides, we should pay attention to prohibiting pesticides that are sensitive to bean moths.

(9) Inducing the concentrated egg-laying of the bean moth

The bean moth lays eggs irregularly in the greenhouse and on the ground. Therefore, during the egg-laying period of the bean moth, the sugar and vinegar solution should be sprayed on the bean leaves to concentrate the eggs of the bean moth on the bean leaves, so as to increase the survival rate of the hatched larvae.

(10) Selection of soybean varieties

The soybean variety should be Dongxin 3, which has high protein content, tall plants and large leaves.

(11) Planting pattern and density

The soybean planting density is 5,000 to 8,000 plants per mu, and the row spacing is not less than 67 cm. Before the soybeans bloom, the rows should be fully ventilated and light-permeable to increase the number of green leaves of the soybeans, making the leaves large, thick and of high quality.

(12) Sowing period

The sowing period of soybeans should be determined according to the emergence and egg-laying period of bean worms. Generally, it should be sown 40 to 50 days before emergence and egg-laying. The sowing period of soybeans in greenhouses should be sown in early February, and the sowing period of soybeans in greenhouses should be sown around March 20. Pests should be controlled 20 days before bean worms emerge, and they should be caught manually.

(13) Sparseness and density make up for sparseness

Since the egg-laying distribution of adult bean worms is uneven, the density should be thinned out in time when the larvae are in the 2nd and 3rd instar so that the larvae can eat enough leaves in time. At the same time, the larvae's exercise volume should be reduced and the nutrient consumption in the body should be reduced.

(14) Harvest in time

The harvesting period should take into account both the market situation and the weight and quality of the larvae. In terms of quality, bean worm larvae should be harvested in time before they enter the soil at the fifth instar stage; in terms of market situation, bean worm larvae can also be harvested at the fourth instar stage. When harvesting, be sure to select larvae with flat heads. Larvae with pointed heads have low nutrition and basically no edible value.

(15) Rotation

When entering the next crop of bean worm breeding period, the greenhouse and shed should be rotated to reduce the base number of pests, which is conducive to bean worm breeding. If the crop cannot be rotated in time, the film and nylon net in the shed can also be removed, deep plowing and watering can be carried out, and insect repellent can be carried out to reduce the pest coefficient.

The above are the key points of bean worm greenhouse farming technology. I hope it can be helpful to the breeders.

Greenhouse farming is very hard work. Temperature, humidity and light need to be monitored in real time. It takes a long time to stay in the greenhouse. If you are not careful, the production will be reduced. It is recommended that you can equip a small device to monitor the temperature, humidity and light intensity in the greenhouse. The "Shed Doctor" developed by Kaiyi Internet of Things is cheap and convenient. It can be directly fixed in the greenhouse without wiring. You can directly check the monitored data remotely with your mobile phone. It is very convenient. If the temperature and humidity in the greenhouse are abnormal, the system will automatically alarm, without worries. Moreover, it can be charged by solar energy, so there is no need to worry about power outages. It can be said to be a must-have tool for greenhouse friends.

6. What are the technical essentials for off-season bean cultivation?

1. Site selection

Taking the cultivation of bean worms in greenhouses as an example, the greenhouses are generally built in places with relatively high terrain and good drainage.

2. Seed selection

(1) When selecting the source of bean worms, you must choose bean worms that are about to be buried in the soil or have already been buried in the soil as the source of seeds.

(2) In terms of characteristics, it is generally necessary to select beans with a ring-shaped or straight stick-shaped shape. Do not choose beans with strong vitality as seed sources.

(2) Covering with film and net: Generally, the film and net should be buried deep in the soil, at a depth of 15-20 cm, to prevent the bean worms from escaping.

7. Indoor breeding technology of bean worms?

1. Choose the field

Bean worms mainly eat soybean leaves. When breeding bean worms, you need to choose well-drained and sunny land as the breeding field, and then apply decomposed organic fertilizer to the breeding field. Then, in late June each year, plant soybeans in the breeding field and use iron fences or wooden fences to enclose the fields.

2. Collecting larvae

When breeding bean worms, you need to capture healthy larvae that are not contaminated by pesticides from wild soybean fields, and then place them in the breeding fields, waiting for September of each year when the bean worms will sneak into the vicinity of the soybean roots to hibernate. The soybeans must be harvested in October of each year, and care must be taken not to plow the soil to avoid harming the bean worms.

3. Pupation and egg laying

Bean worms will pupate in the soil in May and June every year. At this time, soybeans need to be planted again in the breeding fields to provide food for the bean worms. Wait until late June to early August, when the bean worms will hatch into bean hawk moths and then lay eggs on the surface of soybean leaves. Each female moth can lay 200-300 eggs.

4. Feeding methods

When raising bean worms, you need to wait for the eggs to hatch and then raise the newly born larvae indoors. You need to choose a well-ventilated greenhouse or bungalow as the breeding place, put wooden boxes or cardboard boxes in the breeding place, and then place the bean worms in the box. Feed the bean worms with soybean leaves 1-2 times a day.
