Problems solved by technology

However, due to the destruction of forest vegetation, changes in the natural environment, the reduction in the planting area of ​​leguminous plants and cucurbitaceous plants, and the disorderly capture of a large number of human beings, the wild resources of mylabris are constantly decreasing, which is far from meeting the medicinal needs of the market. One of the most scarce animal medicinal materials, the conditions for artificially synthesizing cantharidin are very difficult (need to be carried out under extreme high pressure 1.520Gpa), which leads to a more intense contradiction between the supply and demand of cantharidin. Therefore, the artificial large-scale breeding of cantharidin insects is The key to resolving this contradiction
[0003] At present, there are very few documents on the research on the breeding technology of mylabris, and there is no report on artificial large-scale breeding in production practice.
Tracing it to its main reason, it is mainly that the mylabris larvae are difficult to raise, and the mylabris larvae have a single feeding habit, have natural dependence and specificity on locust eggs, and the larvae have the habit of cannibalism in the growth process; secondly, the mylabris insects are mostly in the wild. One generation occurs in one year, and about 6-7 months of life are in the stop development stage, and the life cycle is relatively long, which greatly reduces the reproduction speed of mylabris
At present, most domestic scholars use locust eggs to raise mylabris larvae, which greatly increases the cost of breeding. Therefore, the research and development of a reasonable formula for artificial rearing of mylabris larvae is the key to the success of artificial large-scale breeding.
But the biggest problem in the breeding process is that the survival rate of young larvae is very low in artificial breeding

preparation example Construction

[0036] The invention provides the preparation method of the artificial feed of described mylabris larvae, comprises the following steps:

[0037] 1) Mix components other than water and agar powder with 35% to 40% of the total mass of water, and homogenize to obtain a homogenate;

[0038] 2) dissolving agar powder and remaining water at 100°C to obtain agar liquid;

[0039] 3) the agar liquid obtained in the step 2) is mixed with the homogenate obtained in the step 1) to obtain artificial feed;

[0040] There is no time sequence limitation between the steps 1) and 2).

[0041] The invention mixes egg liquid, milk powder, bee larvae, pollen, honey, glucose, cholesterol and 30% to 50% of the total mass of water, and homogenizes to obtain a homogenate.

[0042] In the present invention, the rotation speed of the homogenate is preferably 10000-12000 rpm, more preferably 11000 rpm. ; Homogenization time is preferably 2-3 minutes, more preferably 2.5 minutes. The present inventio...

Embodiment 1

[0054] The preparation method of above-mentioned yellow and black small mylabris larva artificial feed is carried out in the following steps:

[0055] 1. Weigh the following components:

[0056] Egg liquid 10g, milk powder 3.0g, bee larvae 10g, rape pollen 3.0g honey 2.5g, glucose 3.0g, cholesterol 0.010g, vitamin C 0.025g and water 60g.

[0057] 2. Stir the above-mentioned egg liquid, milk powder, bee larvae, pollen, honey, glucose, cholesterol and one-third of the total mass of water in a high-speed homogenizer and set aside.

[0058] 3. Dissolve the agar powder in the remaining water, pour it into a container containing the above-mentioned substances after the agar powder is completely dissolved, stir evenly, then pour it into a plate, and divide it into small pieces with a thickness of 1cm after cooling.

[0059] The artificial feed is placed for 2 to 3 months for later use.

Embodiment 2

[0061] The preparation method of above-mentioned yellow and black small mylabris larva artificial feed is carried out in the following steps:

[0062] 1. Weigh the following components:

[0063] Egg liquid 15g, milk powder 2.5g, bee larvae 15g, rape pollen 2.5g honey 3.0g, glucose 2.5g, cholesterol 0.015g, vitamin C 0.020g and water 65g.

[0064] 2. Stir the above-mentioned egg liquid, milk powder, bee larvae, pollen, honey, glucose, cholesterol and one-third of the total mass of water in a high-speed homogenizer and set aside.

[0065] 3. Dissolve the agar powder in the remaining water, pour it into a container containing the above-mentioned substances after the agar powder is completely dissolved, stir evenly, then pour it into a plate, and divide it into small pieces with a thickness of 1cm after cooling. The artificial feed is stored for 2-3 months for later use.

Abstract

The invention provides artificial feed for blister beetle larvae and a preparation method and application thereof and belongs to the technical field of insect feeding. The artificial feed for blisterbeetle larvae comprises the following components in parts by weight: 10-15 parts of egg liquid, 2.5-3.0 parts of milk powder, 10-15 parts of bee larvae, 2.5-3.0 parts of rape pollen, 2.5-3.0 parts ofhoney, 2.5-3.0 parts of glucose, 0.010-0.015 part of cholesterol, 0.020-0.025 part of vitamin C, 1-3 parts of agar powder and 60-65 parts of water. The artificial feed provided by the invention is obtained by mixing the components suitable for the digestive system of blister beetle larvae and capable of providing sufficient nutrients required. Compared with natural feed, the artificial feed has less difference in the aspects of the growth development condition at a larval stage and the body weight of the larvae, the artificial feed can completely substitute the use of the natural feed, and a higher survival rate of the fed blister beetle larvae is achieved.
