Description

Technical Field

[0001] The invention belongs to the technical field of feed processing, and in particular relates to a special feed for wasp larvae in the process of cultivating a standard wasp population. Background Art

[0002] Cultivating standard wasp populations is the most critical link in the large-scale, commercialized, standardized and scientific breeding of wasps. The standard wasp population consists of queen bees, eggs, larvae, pupae, worker bees and other members. Among them, the digestive system of worker bees is degenerate and cannot digest protein and fat. They can only eat nectar, sap, honey, sugar water and other energy foods that do not need to be digested and directly absorbed. The queen bee has a well-developed reproductive system and a degenerate digestive system, and can only eat the rumen of the larvae. The larvae have a well-developed digestive system and digestive glands, and their digestive function is strong. 99% of the larvae's food is food with protein as the main component. At the same time, they also digest and absorb a small amount of vitamins, sap, honey, nectar, sugar water and other foods. The larvae have many types of enzymes that digest and absorb protein foods in their digestive tracts and are highly active. There are no enzymes that digest fat in their digestive tracts, so they cannot digest fat. All the food for the larvae is provided by the worker bees. The worker bees hunt locusts, cabbage worms and other protein foods and nectar and other energy foods from the outside world and provide them to the larvae, and then obtain the rumen nutrition from the larvae's mouth. The larvae in the standard population of wasps maintain a mutually beneficial interdependence between each member through the regurgitated fluid, allowing the colony to develop normally. If there is a problem with the larvae or the regurgitated fluid, the entire standard population will be affected.

[0003] At present, in the process of artificial batch breeding of standard populations, the food for feeding larvae is mainly provided to worker bees through feeding cages outside the nesting room and feeders inserted in the feeding cages. The worker bees then carry the artificially prepared food (feed) into the nesting room to feed the larvae. The food for artificially feeding larvae mainly includes two categories: energy (honey, sugar water) and protein (insects such as locusts, small bees, and various meats). The two types of food are placed in two feeders, which are inserted in the feeding cages. The worker bees take them out of the feeders and carry them into the nesting room to feed the larvae.

[0004] At present, the protein food for artificially fed larvae is mainly the adult insects of artificially bred locusts, bees and other insects, and the lean meat of various animals such as fish. In recent years, due to the increase in the size of the standard breeding population, the demand for protein food has increased. The artificial breeding process inevitably requires the use of feed, additives, hormones, etc. to speed up the production of protein food. Therefore, problems with the types and quality of protein food occur frequently, resulting in digestive tract lesions of the larvae, yellowing, redding, blackening of the body surface, underdevelopment, falling from the hexagonal honeycomb holes, death of worker bees, and queen bee abandonment of the nest. These problems have led to the failure of breeding standard populations, with a heavy loss ratio of about 85%.

[0005] Therefore, in order to completely solve the many problems caused by protein foods in the process of cultivating standard wasp populations, it is of great practical significance to develop a special feed for wasp larvae in the process of cultivating standard wasp populations. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a special feed for wasp larvae in the process of cultivating a standard wasp population. The special feed for wasp larvae in the process of cultivating a standard wasp population prepared by the present invention not only well retains the effective ingredients in the raw materials, but also has a unique flavor.

[0007] The objective of the present invention is achieved through the following technical solutions: A special feed for wasp larvae in the process of cultivating a standard wasp population, comprising the following raw materials by weight: 2-4 parts of wasp pupa cover powder, 1-3 parts of infant amino acid oral liquid, and 4-6 parts of meat paste without fat and hormones.

[0008] Preferably, it comprises 3 parts of wasp pupa cover powder, 2 parts of amino acid oral liquid for infants and young children, and 5 parts of meat paste without fat and hormones.

[0009] The meat paste is one of freshwater fish meat paste, locust meat paste and rabbit meat paste, or a mixture of several of them.

[0010] Preferably, the wasp pupa cover is a white cocoon-like object formed by secretions expelled from the mouthparts of the larvae before pupation.

[0011] The preparation method of the feed comprises the following steps: in a sterile environment, bee pupa cover powder, amino acid oral liquid, and meat paste without fat and hormone are mixed in proportion, processed into round particles with a diameter of 0.1-0.2 cm, and stored in an environment of minus 20°C after bagging.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the process of cultivating standard wasp populations, the traditional food for feeding larvae is lean meat such as locusts, bees, and beef, which has many hidden problems, such as locusts and bees carrying bacteria and viruses, beef carrying fat and hormones, and residual fat and hormones in the digestive tract of locusts (in order to speed up the growth of locusts, locust farmers feed locusts with feed containing fat and hormones, or feed locusts with black vein grass with a large amount of chemical fertilizers and sprayed with growth hormones), etc. The worker bees carry these problematic foods into the nesting room to feed the larvae, causing problems in the larvae's digestive tract and regurgitation fluid, causing the larvae to become sick, and the disease will be quickly transmitted to the worker bees and queen bees (the worker bees and queen bees in the wasp colony mainly feed on the larvae's regurgitation fluid), resulting in the serious consequences of larvae falling from the hexagonal honeycomb (falling off the nest), worker bees dying, queen bees abandoning the nest, and ultimately the death of the standard population during the cultivation of standard wasp populations. The special feed of the present application is processed in a sterile environment to avoid infection by pathogens and viruses. The meat paste of fish, locusts, rabbits, etc. used is raw materials without fat and hormones raised by farmers themselves, avoiding the influence of fat and hormones, ensuring the quality of food in the standard population breeding stage. It was tried out in 36 bases for breeding standard hornet populations in Yunnan Province in 2023 and 2024. There was no phenomenon of larvae turning yellow, red, black, underdeveloped, falling from hexagonal hive holes, death of worker bees, queen abandoning the nest, etc. The success rate of standard populations was above 90%, ensuring the income of farmers breeding standard hornet populations and farmers raising standard hornet populations, laying a solid foundation for the development of the hornet industry. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with embodiments, but the present invention is not limited to the embodiments.

[0014] Example 1 1. Standard population: We define a bee colony consisting of a healthy queen bee, several eggs, several larvae at different developmental stages, several pupae, more than 20 worker bees, and two small bee cakes as a standard population.

[0015] 2. Place a queen bee in the nesting room, put the formula feed in feeder A, and put honey or sugar water in feeder B (energy feed for the activities of queen bees, worker bees, and larvae). After 60 days of artificial feeding and management, a queen bee will develop into a standard population. In the early stage of cultivating the standard population of wasps, there is only one queen bee in the nesting room. The queen bee eats the honey and sugar water in the feeder B in the feeding cage to obtain energy, and eats the feed in the feeder A in the feeding cage to start building the first cake nest and lay the first batch of eggs. The eggs hatch into early-stage larvae in about 5 days (the egg stage is about 5 days). The queen bee uses her mouthparts to take the feed from the feeder A in the feeding cage and carry it into the nesting room to feed the early-stage larvae. This formula feed is larval feed, not queen bee feed. The queen bee only eats the ruminated fluid of larvae and worker bees, and does not eat granular food. After about 26 days, the larvae will not eat or move after pupating (about 21 days in the larval stage). About 40 days, the pupae will emerge and become the first batch of worker bees (about 14 days in the pupal stage). After the first batch of worker bees emerge, the new worker bees carry the formula feed from the feeder A into the nesting room to feed the larvae. This formula feed is larval feed, not worker bee feed. Worker bees only eat the ruminated fluid of larvae, and do not eat granular food. It takes about 40 days from the queen bee building a nest and laying eggs, the eggs hatching into larvae, the larvae pupating, to the pupae emerging as the first batch of worker bees.

[0016] 3. The granular feed is placed in feeder A of the feeding cage. Before the first batch of worker bees come out, the queen bee lifts the granular feed from feeder A of the feeding cage into the nesting room to feed the larvae. The larvae eat the granular feed, digest the granular feed to obtain nutrition, grow and develop normally, and secrete ruminant fluid to feed the worker bees and the queen bee.

[0017] 4. The granular feed is placed in feeder A of the feeding cage. After the first batch of worker bees come out, the worker bees that are constantly emerging will carry the granular feed into the nesting room to feed the larvae in the hive. The larvae will continue to develop and pupate, and the pupae will continue to emerge as worker bees. The worker bees will continue to carry the granular feed to feed the larvae, and the larvae will continue to pupate and the pupae will continue to emerge. In about 60 days, a standard bee colony with more than 20 worker bees will be generated (it takes about 20 days for the first batch of worker bees to emerge and have more than 20 worker bees).

[0018] 5. During the cultivation of standard wasp populations, the food for the larvae also includes honey or sugar water placed in feeder B in the feeding cage. Honey and sugar water mainly provide energy for the larvae, queen bees, and worker bees. Energy food is also carried from the feeder into the nesting room by the queen bee and worker bees to feed the larvae. The granular feed mainly provides protein and amino acid nutrients for the larvae. Artificial provision of high-quality protein and energy nutrient feeds can ensure the normal growth and development of the larvae and the secretion of high-quality ruminant fluid.

[0019] 6. Take the pelleted feed out of the minus 20 degrees environment, restore it to normal temperature in the packaging bag, and then put it into feeder A of the feeding cage.

[0020] 7. In the process of cultivating standard wasp populations, there have always been problems such as high labor intensity, low work efficiency, and difficulty in continuously ensuring the sanitary quality of the feeding area when using live locusts, bees and other insects for feeding. The shape and size of the granular feed are designed according to the mouthparts of the worker bees for easy biting, which is convenient for the worker bees to carry the larvae into the nesting room and for the larvae to feed. At the same time, it is convenient for manual delivery and the feeding area is clean and hygienic, which improves the work efficiency of both workers and worker bees and reduces labor costs and labor intensity.
