Problems solved by technology

Many farmers have low breeding efficiency, often due to improper breeding methods. The existing methods of breeding Tenebrio molitor are mostly wheat bran. Due to the single feed, the insects grow slowly and the individuals are small. The breeding cycle is about 4-6 months, which is long. And the output is low, the waste of feed is large, and the benefit is low

Embodiment 1

[0024] 1. Culture of early stage larvae

[0025] Tenebrio molitor larvae hatched from eggs have a body length of about 2 mm. In addition to eating part of the egg shell, they mainly feed on wheat bran, corn flour, and bean cake powder (70% wheat bran, 15% corn flour, and bean cake powder. 15% as concentrate feed). Each box can raise about 250,000 birds. The larvae in this period grow slowly and need less feed. Keep the concentrate feed 1 cm thick. The concentrate feed and green feed are fed at a weight ratio of 10:1. Sprinkle some finely crushed green feed (grass) on the concentrate feed, about one month The left and right small larvae eat up the concentrated feed, and when the larvae are transformed into ringworm feces, some concentrated feed is sprinkled. The insect excrement should be removed every 15 days, and the feces should be screened out with a 0.5 mm mesh sieve. The temperature of the feed is controlled at 27°C, the relative humidity of the air is controlled at 65...

Embodiment 2

[0042] Different from Example 1, the first stage early stage larva: the ratio of concentrated feed is 60% of wheat bran, 30% of cornmeal, 10% of bean cake powder, and the ratio of concentrated feed to green feed (vegetables) is 12:1. The temperature of the feed is controlled at 27°C, the relative humidity of the air is controlled at 70%, and the water content of the feed is preferably 15%.

[0043] Second stage mid-stage larvae: the ratio of concentrated feed is 70% bran, 15% cornmeal, 15% bean cake powder, and the ratio of concentrated feed and green feed (vegetables) is 7:3. The temperature of feed is controlled at 23 ℃, and air relative humidity is controlled at 65%.

[0044] The third stage late stage larva: concentrate feed and green feed (vegetables) are each 50%, and the ratio of concentrate feed is 50% oil bran, 50% straw powder. The larva grows to more than 25 mm, and the concentrated feed is fed with 70% bran, 15% cornmeal, and 15% bean cake powder for 15 days, and ...

Embodiment 3

[0046] Different from Example 1, the first stage early stage larva: the ratio of concentrated feed is 65% of wheat bran, 20% of cornmeal, 15% of bean cake powder, and the ratio of concentrated feed and green feed (green vegetables) is 15:2. The temperature of the feed is controlled at 23°C, the relative air humidity is controlled at 65%, and the water content of the feed is preferably 16%.

[0047] Second stage mid-stage larvae: the ratio of concentrated feed is 75% bran, 15% cornmeal, 10% bean cake powder, and the ratio of concentrated feed and green feed (melons and fruits) is 8:2. The temperature of feed is controlled at 23 ℃, and air relative humidity is controlled at 70%.

[0048] The third stage late stage larva: concentrate feed and green feed (vegetables) are each 50%, and the ratio of concentrate feed is 60% oil bran, 40% straw powder. The larva grows to more than 25 mm, and the concentrated feed is fed with 75% bran, 15% cornmeal, and 10% bean cake powder for 15 day...

Abstract

The invention provides an effective breeding method for a tenebrio molitor L. A tenebrio molito L is bred by adopting fine fodder with different proportions according to the front period, the middle period, and the late period, simultaneously, straw power and green fodder are adopted as batches, which are reasonably matched in each stage, and nutrition is balanced, the growing speed of a tenebrio molito L is fast, the worm body is large, and the method saves time, labor, and fodder, and the breeding periodic time lasts about 3-4 months, and the method has the advantages of short periodic time, high output and high efficiency, and is suitable to be popularized and bred in a large area.

Description

technical field [0001] The invention relates to a method for cultivating insects, in particular to a method for cultivating Tenebrio molitor. Background technique [0002] Tenebrio molitor is also called mealworm. The larvae are soft and juicy. The body contains 56.58% protein and 28.20% fat. It also contains phosphorus, iron, potassium, sodium, calcium and other macro elements and various trace elements and amino acids necessary for animal growth. It is rich in nutrition and is the best protein material for humans and precious animals. Tenebrio molitor has strong adaptability, has no strict requirements on environmental conditions, and does not require complicated equipment for breeding, and the breeding technology is easy to master, with low cost and high economic benefits. Therefore, the prospect of Tenebrio molitor breeding is promising. [0003] The main purpose of raising Tenebrio molitor is to obtain a large number of larvae, which can be used as live feed for medic...
