I would like to ask what is the scientific name of the barley worm? How to raise it 15

Barley worm is an omnivorous insect, and the concentrate can be prepared with 70% wheat bran, 10% corn flour, 5% flour, 3% bean dregs, 10% fine rice bran, and 2% white tang. Green fodder can be used for vegetable leaves, melon peels, radish, potatoes, pumpkin, sweet potatoes, etc.

Feed feeding of larvae and adults: The feeding of larvae and adults is carried out in a standard feeding tray of uniform specifications, but the feed formula used is different according to the purpose of feeding. There are two kinds of larvae breeding: seed retention and production, and adult breeding is only one type of seed breeding.

Egg collection and hatching: A thin piece of rough paper is attached to the bottom of the standard feeding tray, covered with centimeter-thick feed (or insect droppings), and 600 adults (400 females, 200 males) are placed in each box, and the adults lay the eggs evenly on the oviposition paper, and each piece of paper can lay 10,000 15,000 eggs in 2 days.

Collection and feathering of pupae: the feathering rate of barley worms can generally reach more than 97%, and only a very small number of old larvae with very weak constitution or injuries will die during the feathering process, and the pupation should be released alone.

Barley worms eat wheat bran, various fruits and vegetables, artificial feed, vitamins, fish meal, bone meal, and the feed can be vegetable leaves, melon peels, radish, potatoes, pumpkin, and sweet potatoes. The water is mainly obtained through the intake of rhizomes, thick-leaved vegetables and melon peels, so as to avoid the environment being too dry.

Barley worms can also eat putrefaction (a resource of organic waste from industry and agriculture).

Barley larvae and adults like to eat dry feed, and the water content of the feed is about 15%.

The retained population is fed with fermented wheat bran or other mixed concentrates throughout the whole process; The production group was fed fermented wheat bran (jin) within 10 days after hatching, then fed fermented bran powder for 30 40 days (jin), and then fed fermented wheat bran for 10 days (jin).

The ratio of the main feed: 75% wheat bran, 10% corn flour, 2% fish meal

Adult formula: 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.

"Wheat bran, all kinds of fruits and vegetables, and artificial feed can be eaten. At present, artificial breeding uses wheat bran as the main material, adding various fruits and vegetables, plus sugar, vitamins, fish meal, and bone meal; The water is mainly obtained through the intake of rhizomes, thick-leaved vegetables and melon peels, so as to avoid the environment being too dry. ”

Put some cereal, breadcrumbs and everything!

Buy some oatmeal that doesn't have a sweet taste.

(1) bread worms, also called mealworms; The whole body is yellow (just molted is white).

2) Barley worm is a new variety of bread worm and mealworm hybrid, dark brown and light brown in color, and 3-4 times the body size of breadworm.

c) The nutritional value of barley worms far exceeds that of bread worms.

4) Barley worms reproduce 5 times faster than bread worms and 4 times faster than bread worms.

5) barley worm 55 yuan catty; Breadworm 15 yuan catty.

First, the feed.

There is basically not much difference between the two insects in terms of feed, but the feed remuneration is slightly higher than that of mealworms, and the feed for breeding a pound of mealworms is three catties of wheat bran, plus three to five catties of green fodder. The feed amount for breeding one pound of barley worms is four pounds of wheat bran and five pounds of green fodder.

Second, the insect. The provenance of barley worms is in Southeast Asia, there are few wild barley worms in China, and there are only a few farms in China with a small number of provenances, and the breeding technology is not very mature. Mealworm breeding has a long history in China, and the provenance is distributed all over the country, but the quality of the provenance has been greatly degraded due to long-term family breeding.

In order to obtain a good mealworm provenance, it is necessary to undergo distant hybridization, but the provenance of barley worm is currently in its infancy, and the breeding technology is rarely mastered.

3. Larvae. The larvae of barley worms can reach up to five to seven centimeters at length, while the larvae of mealworms can only reach three to three .5 centimeters at the longest, and the diameter of the body wall of mealworms is only one-third of that of barley insects, and the death ratio of the two insects in the larval stage is very different, and the normal mortality ratio of mealworms is 5 to 25 percent.

However, the normal mortality rate of barley worms is only one to two percent, the breeding cycle is basically the same, the feed cost of barley worms is one-third higher than that of mealworms, and the current market price of barley worms is stable at 40 to 70 yuan, while the market price of mealworms is generally in the range of 5 to 10 yuan. In terms of economic benefits, the economic benefits of barley worms are 5 to 8 times higher than that of mealworms.

Mealworms and barley worms have different differences in origin, larval appearance, adult appearance, and nutritional value.

1. The place of origin is different.

Mealworms: Native to North America, China was introduced from the Soviet Union in the 50s of the 20th century and raised.

Barley worm: Native to South Africa and Central Africa, China has only introduced it from Southeast Asian countries in recent years.

2. The larvae have different shapes.

Mealworm: the body is slender, cylindrical, the body length of the mature larvae is (24 29) mm, the first hatched larvae are milky white, and then turn yellowish-brown, the anterior and posterior margins of each segment are light brown, the internodes and ventral surface are yellowish-white, and the body length and head width of each instar larvae are relatively stable, which is the main basis for larval ageing.

Barley worms: larvae are generally 40 60 mm long, about 5-6 mm wide, and a single worm weighs and is cylindrical. Its body wall is hard, yellowish-brown, shiny, with 13 segments, and the joints of each segment have yellowish-brown rings, and the ventral surface is yellow.

During larval growth, the body color first appears white. After the first molt, it turns yellowish-brown, and then molts once every 4 6 days, and molts a total of 6 10 times in the larval stage. The growth period is 60 days.

The larvae begin to molt from the beginning, and their activity begins to decrease before molting, and the larvae that have just molted are milky white and very fragile. Most vulnerable.

3. The appearance of adults is different.

Mealworm: the adult is flattened and oblong as the whole, the body shape is long (, the body ( mm, the elytra of the newly emerged adult is beige, the anterior thorax and dorsal plate are brown, the elytra will turn reddish-brown after 3 hours, and after 3 4 days, the elytra of the adult will change to black-brown and the antennae will be rosary-shaped.

Barley worm: the shell that has just molted is milky white, the head is orange, the carapace is relatively thin, the back becomes black-brown after 1 2 days, the abdomen becomes yellow-brown, the whole is oval, the length is about 25 30 mm, the width is about 8 mm.

Mealworms: <>

Barley Worm: <>

3. The nutritional value is different.

Mealworm: Mealworm dry products contain 30% fat, more than 50% protein, phosphorus, potassium, iron, sodium, aluminum and other macro elements and a variety of trace elements. Because the dried mealworm larvae contain about 40% protein, the pupal contains 57% protein, and the adult contains up to 60% protein, it is called the "treasure trove of protein feed".

Barley worms: The nutritional value far exceeds that of larval crickets and mealworms, and contains a large number of trace elements necessary for the human body.

1. The scientific name of the insect born in the wheat is Gu Xiang;

2. The grain elephant is the main pest of stored grain. Adults feed on the kernels, and the larvae eat the inside of the grains. harm rice, rice, wheat, corn, sorghum, etc.;

3. The grain elephant is oval, reddish-brown wax to asphalt color, and the back is dull or slightly shiny. The head is notched, and the anterior end of the forehead is flattened. The base of the beak is thick, the prothorax is about the same length and width, and the base is broad and narrowed anteriorly.
