1. I want to raise wasps. How is the current sales? Where are they sold? Is the breeding technology difficult?

It seems that raising hornets is quite troublesome, but it is also a good choice to poke a hornet's nest when you have nothing to do.

2. How many pupae can yellow-legged hornets produce on average per nest when bred artificially?

The price is calculated by kilogram. The price of a late-stage queen bee is at least 300 to 400 yuan, and at most several thousand yuan.

3. How to raise bumblebees?

Medicinal wasps are the whole of Vespidae and Vespa nigrofaciens. Their larvae, honeycombs and venom can all be used as medicine. The medicinal materials are bumblebee (whole), bumblebee larvae, and honeycomb. Medicinal wasps are sweet and spicy, warm in nature, and mainly treat rheumatism and arthritis. Wasp wine can dispel rheumatism and treat acute and chronic rheumatism and rheumatic arthritis; its larvae (bumblebee larvae) have the same effect; honeycombs have the effects of relieving pain, dispelling wind and expelling parasites, reducing swelling and detoxification, and mainly treat epilepsy, rheumatism, furunculosis, toothache, mastitis, stubborn ringworm, cancer, etc.; wasp venom is used to treat inflammation, and has anti-cancer and anti-radiation effects, which has attracted the attention of medical circles in various countries. Medicinal wasps are natural enemies of agricultural and forestry pests. The medicinal insect research group of the Haimen Scorpion Breeding Consultation Station in Jiangsu Province once tried to release a certain amount of medicinal wasps in vegetable gardens and cotton fields for experiments. In 10 days, the cabbage worm and cotton bollworm were completely eliminated, achieving the effect of biological control. Artificial breeding of medicinal wasps is simple and easy, requires little labor and does not require much investment. It only requires catching some female wasps for domestication and breeding. It is a good way for farmers to get rich and should be promoted. The following is a brief introduction.

1. Construction of the Medicinal Wasp Domestication Cage

Generally, the cage for breeding medicinal wasps is made of wood frame, with nylon mesh on the top and sides, and a thickened nylon zipper opening on one side (for management personnel to enter and exit). The cage is usually bottomless, buried in the soil, and fixed with wooden stakes and wire to prevent it from being blown down by the wind. A large number of cruciferous plants and small shrubs are cultivated in the cage.

2. Cultivation of medicinal wasp feed

Generally, when domesticating medicinal hornets, it is easiest to cultivate Pieris rapae. The method is to mash the leaves of cruciferous plants (cabbage leaves are best), apply the juice on a clean piece of paper, and then place the coated paper in the field. Soon many white cabbage butterflies will rush over and quickly land on the paper to lay eggs. When a certain number of eggs are laid, the paper can be taken to the leaves of cruciferous plants in the beehive, allowed to hatch and grow naturally, and provided for the medicinal hornets to prey on.

3. Making of medicinal wasp catching tools

To capture wild female bees for domestication, you can use a homemade bee-catching net. The net consists of a handle, a net ring, and a net bag. The length of the handle is about the same as your height, and you can use a bamboo pole or a wooden stick with a diameter of 2 cm. The diameter of the net ring is 35 cm, and it is made of thick iron wire, with both ends folded into right angles and fixed on the handle. The handle is made of dark nylon gauze, and the length of the net bag is about twice the diameter of the net ring. If it is convenient, you can also go directly to the fishing gear store to buy a landing net and replace the nylon gauze.

4. Methods of catching medicinal wasps

The medicinal wasps that are active in the wild in spring have all mated before hibernating in winter. They can be domesticated after being captured. The capture method is as follows. 1. If you find a medicinal wasp flying in the air, just wave the bee-catching net. After the bee enters the net, quickly swing the bottom of the net upwards, flip the bee upside down, and then put it in the training cage and let it fly out by itself. 2. If you see a medicinal wasp on a flower, you should walk over gently and startle it. When the medicinal wasp flies up, swing the bee net violently, and you can accurately catch the medicinal wasp in the net. This operation can avoid damage to the flowers. 3. If you encounter a medicinal wasp landing on a plant with thorns, you must wait until the medicinal wasp flies up before catching it, otherwise the thorns on the plant will tear the bee net. .

5. Domestication of medicinal wasps

The captured male bees are placed in a training cage, which contains fibrous materials such as rotten wood (for the male bees to build nests), and clean water and liquid feed are fed. The general feeding method is to use absorbent filter paper or absorbent cotton to soak the liquid feed into a saturated state, and then put it into a glass container for feeding. The disadvantages of this feeding method are: it is very easy to evaporate, dry, contaminate, and mold. The most ideal method is to first put water and liquid feed into a bottle, and then invert the bottle in a glass container covered with absorbent filter paper and absorbent cotton. Through osmosis, the medicinal wasps are provided with food, which can avoid the above disadvantages. In the cage, according to the number of captured female bees, hang empty beehives (for the medicinal wasps to build nests). Generally, when the temperature is constant above 17℃, medicinal wasps begin to fly into the empty beehives hanging in the training cage to build nests and lay eggs. At this time, the female wasps not only build nests and lay eggs, but also have to bear the task of catching and feeding larvae. After the larvae become pupae, they can emerge as bees in about 15 days. The first generation of adult bees will be responsible for building nests and feeding larvae. The original male bees only bear the task of laying eggs. At this time, the medicinal wasps are very attached to the nest and are generally unwilling to leave the nest and fly out. As the bee colonies and larvae on the nest continue to increase, there must be enough cabbage worms to ensure adequate feed supply. If the feed is insufficient, it will cause the medicinal wasps to eat the larvae.

6. Field release of medicinal wasps

When the first generation of adult bees emerge, the beehives can be moved directly to the field. They do not need to be managed by humans or fed with any feed. The adult bees will catch all kinds of pests for food. General management During the period of yellow-tailed brood borer, be sure to close the door of the beehive at night to prevent yellow-tailed brood borer from entering the hive to lay eggs at night and harm the larvae of medicinal wasps.

7. Wintering Management of Medicinal Wasps

In early October, bring the beehives in the field into the beehive cages and feed them with lepidopteran insects and sugars to increase the nutrition of the bees and replenish their physical strength. When the temperature drops below 6°C, the medicinal wasps will enter the beehives and huddle together for the winter, not eating or moving. At this time, the beehives should be placed in a dry and ventilated empty room. When the temperature rises above 6°C, the medicinal wasps begin to disperse. When the temperature is constant at above 13°C, the medicinal wasps begin to go out one after another, and at this time they should be put in the beehive cages for feeding. When the temperature is constant at above 17°C, the medicinal wasps enter the nesting state.

8. Collection of medicinal wasp products

1. Collection of adults and larvae. For artificially raised medicinal wasps used to control agricultural and forestry pests, collection should be done when pest control is about to end. Generally, collection is done in October when the beacon boxes are taken back from the fields to the beehives, and sufficient female bees can be guaranteed for the next year. Then the excess adult bees and larvae are collected, scalded to death with boiling water, and dried in the sun or in an oven to become Chinese medicinal bumblebees and bumblebee broods, which are stored in dry porcelain or jars. 2. Collection of beehives. Collection of beehives is relatively convenient and easy. Collection should be done when medicinal wasps huddle together for wintering. The honeycombs in the beehives are removed and dried in the sun to become Chinese medicinal dew beehives. 3. Collection of medicinal wasp venom. Medicinal wasp venom is a kind of venom stored in the venom sac of the bee. It is a highly complex mixture of pharmacological and biochemical activities and can be obtained by electrical stimulation. Before collecting the venom, first move the beehives in the field into beehives at night, and place the venom collector at the entrance of the beehive after daybreak. When the medicinal wasps touch the stimulator of the venom collector, they are electrocuted and release venom. After collection, dissolve it in distilled water, centrifuge to remove dust, and then freeze-dry to obtain venom dry powder, which is then stored in a refrigerator.

IX. Control of natural enemies of medicinal hornbeam

1. Yellow-tailed brood borer. Yellow-tailed brood borer belongs to the order Lepidoptera and the family Pyralidae. The first generation of adults occurs in mid-to-late May. The adult body is 7.5 mm long and has a wingspan of about 17 mm. The male moth is slightly smaller than the female moth. After the adult emerges, it quickly mates and flies to the nest of medicinal wasps at night to lay eggs. The adult moth dies after 3 days. The larvae of the yellow-tailed brood borer eggs hatch in about 5 days. They are grayish white and move flexibly in the hive, eating the larvae of medicinal wasps. The larvae of the yellow-tailed brood borer pupate in about 12 days, and the second generation of yellow-tailed brood borer adults emerge after about 11 days of pupal stage. The yellow-tailed brood borer has a generation of about 30 days, has a very strong reproduction rate, and is active at night. The medicinal wasps are active during the day and rest on the nest at night, allowing the yellow-tailed brood borer to lay eggs in the hive. It can be seen that once the yellow-tailed brood borer invades the beehive, it is very likely that a large number of beehives will be in danger of being destroyed. Prevention and control methods: According to the characteristics of the yellow-tailed brood borer that it is not good at flying high, the beehive of the medicinal wasp is generally higher than the ground, and the beehive door is closed every night to prevent the yellow-tailed brood borer from entering the beehive to lay eggs. The damper is opened the next morning to let the medicinal wasps go out. 2. Mice. Mice mainly harm the medicinal wasps that huddle together for the winter. If there are mice in the overwintering beehive, they often eat up the overwintering huddle bees in the whole box, so prevention must be taken as soon as possible.

10. Economic Value of Medicinal Wasps

Wasp nests are traditional Chinese medicinal materials. The state purchase price is 17 yuan per kilogram. Each wasp nest is generally about 50 centimeters in diameter. It is not a problem for an ordinary worker to raise thousands of nests of medicinal wasps. On average, 250 grams of wasp nests can be collected from each nest, and the economic benefits are considerable. In recent years, domestic and foreign reports have shown that wasp venom has anti-inflammatory, anti-cancer and anti-radiation effects, which has attracted the attention of the medical community. In the world's largest toxin company, Sigma, the price of one ounce of wasp venom is as high as about 30 US dollars. Medicinal wasps are natural enemies of agricultural and forestry pests and can be used for biological control to eliminate pests. In grain, cotton and cash crop fields, raising a certain amount of medicinal wasps can save the cost of pesticides for insect control, increase production and increase income. Putting medicinal wasps in vegetable gardens can reduce the pollution of pesticides to vegetables.

11. Precautions for breeding medicinal wasps

1. When collecting the venom of medicinal wasps, they are extremely violent and are most likely to sting people. It is necessary to close the beehive door at night and then put the beehive into the cage. After dawn, open the beehive door and turn on the electricity to collect the venom. People must observe from outside the cage. After dark in the evening, take out the collected venom, close the beehive door, and then put the beehive back into the field. 2. Two types of wasps that are not suitable for breeding. ① Golden-ringed wasp. This wasp has a violent temper and often attacks humans and livestock in groups. It is extremely toxic. If it stings a buffalo, it can make the buffalo anesthetized and lie on the ground. If a person accidentally pokes a golden-ringed wasp nest, a large group of golden-ringed wasps will fly over and attack, causing serious injuries or even death. ② Tussah wasp. This wasp specializes in preying on tussah silkworm larvae. It is a pest and is not suitable for breeding. It should be killed. (
