Wasps, also known as wasps, are known to have more than 5000 species in the world, and more than 200 species have been recorded in China, which are widely distributed in China. Wasp taste sweet, warm, mainly for rheumatism arthralgia. Honeycomb can be used as traditional Chinese medicine, with pain, deworming, detumescence and detoxification effect, the main treatment of epilepsy, wind arthralgia, mastitis, toothache, stubborn ringworm, cancer and so on. Wasp wine can dispel wind and dehumidification, treat acute, chronic rheumatic pain, and rheumatoid arthritis. Wasp venom can treat arthritis and has high medicinal value, which is of great significance to the development and production of new medical products. At present, more than 20 kinds of wasp venom are sold in the international market, and their prices are very expensive. In addition, wasp larvae and pupae are rich in nutrients, which can develop a variety of nutritious foods. Therefore, breeding wasps has high economic benefits and broad development prospects.

The wasp's life includes four insect states: egg, larva, pupa and adult. There are three generations in a year, the first generation adult Eclosion in mid-June, the second generation from mid-June to early July, the third generation Eclosion from mid-July to early-August, mating in late October and overwintering. Most of the drones appeared in the third generation, died after mating and had a short life span. Overwintering drones are clustered and often gather together to survive the winter to resist the cold. In spring, female bees build nests by looking for food alone, and usually build nests in trees or in tree holes. Adults prey on Lepidoptera larvae and eat fruit juices and tender leaves.

Wasp breeding equipment

1. Beehive. Made of wood or made of iron gauze, the volume is about 0.03 to 0.04 cubic meters, so that it has full room for movement.

2. Bee shed. The size depends on the number of beehives harvested. Large glass greenhouses, large factories or special beekeeping sheds can be used. The beehive uses iron and wood as support and iron window screen as purse seine, with a general area of about 100 square meters and a height of 2m. Corn, soybeans, cotton and other crops that are easy to access insects are planted in the shed, and there is a screen door on one side of the shed. Small plates containing honey, fruit, melon peel and other fodder should be hung in the shed so that the bees can feed and move freely after they are put in.

3. Beehive. It is made of wood, with 15~20cm on the side, and a cover and bottom made of thin wood. The cover is equipped with hooks, a screen window is hung around it, and a trap door is left on one side.

Feed for wasp culture

Fruits, such as ripe apples, peaches, vegetables with more moisture, molasses, melon peels, etc.

The living habits of wasps

Wasps are insect groups with social behavior. The species of the family Carpinidae usually have no nests and live freely. During spawning, the female bees build a mud chamber or choose a suitable bamboo tube, lay eggs in it, and store the larvae or spiders of other insects anesthetized by stings after being caught. One egg in one chamber is sealed separately, and the larvae hatched by the eggs feed on the stored prey. After pupation and Eclosion into bees, they bite through the nest mouth and fly out.

Other species of wasps live in nests all their lives. There are differences between queen bees, professional bees (or worker bees) (females) and drones in the colony. The queen bees are the females who mated and fertilized with the drones after the autumn of the previous year. They stored their sperm in seminal vesicles and used them in different stages during mating. Drones die soon after mating. When the weather is getting cold, fertilized female bees leave the nest one after another to look for places such as cracks in the walls and haystacks to stay together for the winter. In the spring of the following year, the surviving females went out in groups to find suitable places to build nests and lay eggs. The fertilized eggs they lay form females and the unfertilized eggs form drones. Due to the increase in the number of professional bees, the hive is gradually expanding. Professional bees are responsible for nesting and feeding larvae. There are three peaks in central China every year. After autumn, the number of drones in the nest accounts for about 1 / 3 of the total, which is the period of the year with the most drones.

In general, wasps stung at 12: 13 ℃, nesting began at 16: 18 ℃, and overwintered when the temperature dropped to 6: 10 ℃ after autumn. Activities are most frequent when the temperature is high at noon in spring and hot at noon in summer, and activities are often suspended. Return to the nest at night. Have the habit of liking light. The wind stops when the wind is above force 3. It is most suitable for activities when the relative temperature is 60% ~ 70%. Stop going out on rainy days. Wasps are addicted to sweet substances. Within 500 meters, the wasp can clearly identify the direction and return to its nest smoothly, while more than 500 meters often get lost.

Wasp culture management

The key problem of raising wasps is to protect female wasps safely through winter, and to guide early nesting and more nesting in spring.

1. Collection. At the end of September and the beginning of October every year, wasps begin to break away from their old nests and migrate to suitable places for the winter, when it is the most appropriate time to collect wasps. At night, the insects are collected in the overwintering place of the bees and raised in the beehive. Each beehive is put into 300 to 500 heads, shaded by black cloth and placed in a dry, ventilated and undisturbed chamber to reduce activity and promote it to go into hibernation ahead of time. In order to avoid that the colony is not easy to find after leaving the nest, it can also be harvested on the original nest in the middle of September and placed in a cage or box, making use of the upward habit of the swarm bees to put ripe apples, peaches and water-rich green vegetables at the bottom of the cage. When the temperature is high at noon, bask in the sun for 3 to 4 hours, make it active and feed, postpone the dormancy period, not only replenish the nutrition, but also make it safe to survive the winter. Wasps are semi-hibernating insects, and the lower the temperature is, the tighter the clump is. When the temperature is higher than 7 ℃, the wasp begins to break up, and the survival rate after overwintering is mainly related to the quality of clumping. Therefore, during the overwintering period, the hugging condition should be checked frequently and once in the cage 10-15 days. If you find that the group is scattered, you should cool down in time and thicken the shading coat.
