How to catch barley worms, how to raise barley worms

Barley worm is a larva of the family Pseudocarpidae, which was introduced from Southeast Asian countries in recent years. The maximum body length of mature larvae is about 6 cm, which is 3-4 times larger than that of ordinary mealworms, and the yield is 5 times that of mealworms, and the nutritional value is far greater than that of larval crickets and mealworms. Adult females are significantly larger than adult males.

Because it contains a large number of trace elements necessary for the human body, it is believed that it will soon replace mealworms into large hotels and restaurants, and it will be finely processed to become a big meal on people's plates, and will be more popular with people from all walks of life in large and medium-sized cities.

Barley insects are large, the growth cycle and speed are the same as mealworms, the feeding is miscellaneous, the adaptability is wide, mainly bran, vegetables, melons and fruits, the feed is extensive, the feeding cost is low, suitable for residents around our country to raise, its yield is 3-4 times that of mealworms, and the economic and social benefits are very significant. Barley worm breeding started earlier in the international market, and domestic breeding has not yet been reported to be successful in large-scale farming. Since the introduction of this demonstration farm in 2005, through long-term testing and breeding, it has fully grasped its ecological habits and growth and reproduction laws, solved key technologies such as farrowing room setting, feed formula, temperature and humidity control, pupa feathering, etc., and scientifically summarized a set of optimal breeding models, providing a strong bait guarantee for the rapid development of special aquatic animals and rare livestock and poultry.

As a protein source of high-grade bait, barley worms have a very broad market demand at home and abroad. The price of foreign barley worms is 15 cents per piece, and the price is 1,000 yuan based on 700 pieces per kilogram; The domestic market is 100 yuan per kilogram, and there is often a situation of price and no goods, so it has broad market potential and demand. Barley worm breeding technology is roughly the same as mealworm, but in the plant setting, feed formula, temperature and humidity control and pupa feathering and other important links are slightly different, once the farmer has technical training, you can master the essentials, independent operation.

The main equipment of barley worms is mesh sieves and feeding containers. Mesh sieve box: for adult eggs to lay eggs, and is also a tool for separating eggs, insect bodies and bait.

It can be framed with a wooden box with a mesh of 3 mm. Containers: cabinets, boxes, pools, boxes, etc.

The size of the cage depends on the amount of insects, the maximum is 70 cm, 45 cm and 18 cm (we all use this plastic frame for breeding). The inner wall of the container should be smooth around it to avoid barley insects from crawling out and prevent spiders, geckos, praying mantis and other insects.

It is best to choose a place to raise barley worms in a leeward and sunny house, warm in winter and cool in summer, the light should not be too strong, keep warm, the most suitable temperature is 18 30, relative humidity 70%. In summer, when the temperature is high, sprinkle water on the ground to cool down; In winter, it is necessary to keep warm to ensure the normal growth and development of barley worms.

Prepare containers: Prepare mesh sieve boxes and other breeding containers for breeding barley worms. Feed Selection:

To feed barley worms, feed should be prepared, vitamins and pig mixtures should be added to increase the amount of eggs produced. Control the temperature: the ambient temperature is controlled at about 18-30 degrees, and the humidity is 70%.

Precautions: The inner wall of the feeding container should be smooth to avoid being infringed.

1. Prepare the container

Breeding barley worms to prepare a mesh sieve box and breeding container, the mesh sieve box is used for the adult barley worm to lay eggs, but also used to separate the eggs and place bait, the selection of breeding containers is more diversified, the size of the size according to the number of barley worms to choose.

2. Feed selection

Feeding barley worms requires a mix of feed, 50% wheat bran, 4% fishmeal, 15% duck feed, 1% mixed salt, 4% sugar and 26% fermented bran, while adding an appropriate amount of vitamins and pig mixture, which can prolong the life of barley worms and increase the number of eggs it lays.

3. Control the temperature

Breeding barley insects choose leeward, sunny, warm in winter and cool in summer, the light can not be too strong, the ambient temperature is controlled at about 18-30 degrees, the air humidity is 70%, when the temperature is high in summer, water should be sprinkled on the ground to cool down, and the winter is to do a good job of keeping warm.

4. Precautions

During the breeding of barley insects, we must do a good job of epidemic prevention, common geckos, spiders, praying mantises, etc. in daily life are the natural enemies of barley insects, so the inner wall of the feeding container should be smooth to avoid being infringed, and the dead barley insects should be removed as soon as possible to ensure that the breeding environment is clean.

1.Feed formula for larvae: 35% wheat bran, 35% full feed for pigs (or full feed for ducks), 10% soybean cake, 20% after fermentation, 50 grams of compound vitamins for feed (Jinsavi), 80 grams of premix for pigs (100 days of slaughter), and 250 grams of mixed salt for feed.

2.Adult recipe: 50% wheat bran, 4% fishmeal, 15% full feed for pigs (or ducks), 26% fermented straw or bran, 4 sugar, 1% mixed salt.

In addition, 50 grams of feed multivitamins (Jinsaiwei), 80 grams of pig premix (100 days of slaughter), and 250 grams of mixed salt for feed were added. This formula is suitable for adult worms during the oviposition period, which can prolong the life of adults and increase the amount of eggs produced.

The processing method of the above two kinds of feed formula is: mix the various ingredients well, because the fermented straw is added is wet material, it can be fed directly by mixing, barley worms love to eat, and the mixed material should be fed immediately; You can also add an appropriate amount of water to knead it into a ball, press it into a small cake shape, and use it after drying. Farmers with conditions can use the feed pellet machine to puff into pellets.

The above-mentioned feed formula has proved to be very effective, cannibalism rarely occurs, the growth condition is good, and there is no disease at present. Please refer to the relevant information for the treatment method of straw and bran. The above feed is concentrate feed, in addition to the need for concentrate feed, the barley worm also needs a large amount of green feed, melon peel, vegetable leaves, etc., we in addition to these green feed, more is fed to rye grass and royal bamboo grass, royal bamboo grass is best to be simply broken and fed.

The ratio of concentrate feed and green feed is generally about 1:2. The cost of rearing 1 kg of barley worm larvae is preliminarily calculated as:

About kilograms of concentrate feed, about 3 kilograms of green feed. With the maturity of breeding technology, the cost of breeding will be further reduced.
